Luxury watch straps are often judged first by their material, color, or appearance. Yet on a precisely engineered sports watch, the most important details are frequently the ones that are least visible.
The connection between the strap and the watch case. The geometry surrounding the spring bars. The transition from the lugs to the wrist. The taper toward the buckle. The location of each adjustment hole. Even the relationship between the rubber and the metal hardware contributes to how the completed watch feels and performs.
The Rubber B Tang Buckle Series approaches the traditional pin-buckle watch strap through this engineering perspective.
Rather than treating the strap as a universal accessory attached according to lug width alone, Rubber B develops model-specific configurations for compatible luxury watches. The result combines the familiarity of a traditional tang buckle with the precision fit and Swiss-Made vulcanized rubber construction associated with Rubber B.
It represents a different philosophy from the Rubber B Classic Series.
Where compatible Classic Series straps are designed to integrate with an original manufacturer’s deployant clasp, the Tang Buckle Series creates an independent strap-and-buckle system.
The buckle may be traditional.
The engineering surrounding it is anything but.
What Is the Rubber B Tang Buckle Series?
The Rubber B Tang Buckle Series is a collection of Swiss-Made vulcanized rubber watch straps designed for compatible luxury watch references and fitted with a traditional tang-style buckle configuration.
On many models, the system incorporates Rubber B’s proprietary Blocked Integration™ engineering at the watch case. The strap is calibrated specifically for the dimensions and geometry of the intended watch rather than being designed as a generic rubber strap based only on lug width.
At the opposite end of the strap, the Tang Buckle Series uses the familiar pin-and-frame closure found on traditional leather and rubber watch straps.
Many current configurations include a Rubber B tang buckle manufactured from 316L stainless steel, while certain models use specially proportioned Fine Tang Buckle or Flared Tang Buckle designs according to the requirements of the watch and strap.
This gives the series a distinctive architecture:
model-specific integration at the watch case combined with a traditional buckle closure at the wrist.
Why Create a Tang Buckle Series?
For decades, luxury sports watches have frequently been delivered on metal bracelets or deployant-style straps.
The deployant clasp offers its own advantages, and Rubber B’s Classic Series was developed around the idea of preserving compatible original manufacturer clasp hardware while changing the material surrounding the wrist.
The Tang Buckle Series takes another approach.
Instead of relying on the watchmaker’s original deployant clasp, the strap operates as its own complete closure system.
This allows the original bracelet and clasp to remain together while the watch is worn on rubber.
For collectors who periodically transition between bracelet and strap configurations, this can simplify the experience. The factory bracelet does not necessarily need to be separated from its clasp simply to install the rubber configuration.
The result is also visually different.
A tang buckle gives the watch the appearance and wearing characteristics associated with a conventional strap rather than recreating the feeling of a bracelet-style closure.
This distinction is fundamental to understanding the Tang Buckle Series.
It is not simply the Classic Series with different hardware.
It represents a separate approach to how a luxury sports watch can be worn on vulcanized rubber.
Tang Buckle vs Deployant Clasp
A tang buckle is one of the most established closure systems in watchmaking.
Its principle is straightforward.
A metal frame surrounds one section of the strap. A movable pin, traditionally called the tang, passes through one of several adjustment holes in the opposite strap section. One or more keepers then secure the remaining length of the strap against the wrist.
A deployant clasp works differently. Instead of passing a pin through the strap each time the watch is worn, hinged metal sections unfold and close around the wrist.
Neither architecture is universally superior.
They simply create different wearing experiences.
Tang Buckle
A tang buckle offers:
- straightforward operation;
- conventional strap adjustment;
- a compact closure;
- a traditional watch-strap aesthetic;
- independence from many original bracelet clasp systems.
Deployant Clasp
A deployant clasp can offer:
- folding metal closure architecture;
- reduced need to pull the strap through a buckle;
- familiar operation for owners accustomed to metal bracelets;
- integration with compatible original manufacturer hardware.
Rubber B therefore offers different strap architectures according to the desired configuration rather than treating every watch and wearer identically.
Classic Series vs. Tang Buckle Series
The distinction between the two collections becomes particularly clear when examining how each interacts with the watch’s original hardware.
Rubber B Classic Series
Compatible Classic Series configurations are engineered to work with the original manufacturer deployant clasp.
For certain Rolex applications, for example, this allows the watch to transition from its metal bracelet to vulcanized rubber while retaining the appropriate original Rolex Oyster deployant clasp.
The clasp remains part of the wearing system.
Rubber B Tang Buckle Series
The Tang Buckle Series replaces the need for that deployant configuration with a traditional tang-buckle closure.
This creates a more independent strap system.
The watch case remains precisely integrated with the Rubber B strap, while the opposite side terminates in its own buckle rather than relying on the original bracelet clasp.
Both systems therefore begin with the same broad question:
How should a rubber strap integrate with a luxury watch?
But they arrive at different answers.
Engineering the Strap From Case to Buckle
A high-quality tang-buckle strap requires more than attaching a metal buckle to a molded piece of rubber.
The entire strap must function as a system.
At the watch case, the strap must match the dimensions and shape of the intended reference.
Around the wrist, the rubber must bend predictably without creating unnecessary bulk.
Toward the buckle, the strap must taper according to the proportions of the watch.
The adjustment holes must be positioned appropriately.
The buckle must correspond with the thickness and width of the strap.
The keepers must retain the excess strap securely while allowing it to move naturally when the watch is fastened.
The surface must remain comfortable against the skin while maintaining the structural characteristics necessary for repeated wear.
These details are particularly important with a tang buckle because the same areas of the strap are repeatedly flexed as the watch is put on and removed.
Material formulation and geometry therefore become inseparable.
Blocked Integration™ at the Watch Case
One of the defining principles behind many Rubber B collections is Blocked Integration™.
Rather than leaving a visible gap between the strap and the watch case, compatible Rubber B straps are engineered to follow the contours of the specific watch for which they were designed.
Internal structural components can be incorporated around the attachment area to help stabilize the strap where it meets the case.
The goal is a controlled and precise connection rather than the movement that can occur when a conventional straight-ended strap is installed between curved watch lugs.
This distinction is particularly important on modern luxury sports watches.
Cases such as the Rolex Submariner, GMT-Master II, Daytona, Explorer, Sea-Dweller, and Tudor Black Bay each possess their own proportions and lug geometry.
A strap designed only according to nominal lug width does not account for all of those differences.
Blocked Integration™ treats the watch case itself as part of the engineering equation.
The result is one of the defining contrasts within the Tang Buckle Series:
The buckle follows traditional watchmaking principles, while the connection at the case is model-specific and highly engineered.
The Rubber B Signature T Design
Many Tang Buckle Series straps incorporate Rubber B’s recognizable signature T design.
This visual architecture helps define the transition of the strap as it moves away from the watch case and toward the wrist.
The design is not simply decorative.
Proportion plays an important role in how a large luxury sports watch appears once it is removed from its original metal bracelet.
A strap that remains excessively broad from the case to the buckle can make the watch appear visually heavy.
A strap that tapers too aggressively can create the opposite problem, making the watch head seem disproportionate to the closure.
The transition must therefore be carefully controlled.
Rubber B uses model-specific proportions and tapering to create a visual relationship between the watch case, the strap, and the buckle.
This is especially noticeable on substantial sports watches such as the Submariner, GMT-Master II, Sea-Dweller, and Daytona.
The 316L Stainless-Steel Tang Buckle
Many Rubber B Tang Buckle Series configurations are supplied with a buckle manufactured from 316L stainless steel.
316L has long been associated with premium watch and jewelry applications because of its balance of strength, corrosion resistance, and finishing capability.
That makes it particularly appropriate for a component that comes into frequent contact with:
- perspiration;
- humidity;
- water;
- changing temperatures;
- repeated mechanical movement.
The buckle also plays a structural role every time the watch is fastened.
The tang must enter the selected adjustment hole cleanly.
The frame must support the strap without excessive movement.
The proportions of the buckle must correspond to the taper and thickness of the rubber.
These considerations demonstrate why the closure should be viewed as part of the complete strap architecture rather than as a separate accessory.
Fine Tang Buckle and Specialized Configurations
The Tang Buckle Series is not limited to one identical buckle architecture across every watch.
Certain references require different proportions.
For example, Rubber B offers configurations using a Fine Tang Buckle, including an 18 mm 316L stainless-steel version used with selected watches such as the Tudor Black Bay 58.
Other configurations have used a Flared Tang Buckle Series, including applications developed for larger watches such as the Rolex Deepsea.
These variations illustrate an important Rubber B engineering principle.
The objective is not to force a universal buckle system onto every watch.
Instead, strap width, taper, case diameter, wrist presence, and watch architecture can determine the most suitable closure proportions.
A Tudor Black Bay 58 should not necessarily require the same strap geometry as a Rolex Deepsea.
Model-specific engineering continues beyond the lugs.
Why Vulcanized Rubber Matters in a Tang-Buckle Strap
The material requirements of a tang-buckle watch strap are demanding.
Each time the watch is put on, the strap bends around the buckle.
The tang enters an adjustment hole.
The excess length passes through the keeper system.
The rubber then curves around the wrist for hours at a time.
When the watch is removed, the process occurs in reverse.
This cycle can happen thousands of times during the life of the strap.
Rubber B manufactures its principal rubber straps in Switzerland using vulcanized rubber formulated specifically for wristwatch applications.
The material is not simply chosen because rubber is water resistant.
Its role is structural.
A tang-buckle strap must balance flexibility with dimensional stability.
It must bend without feeling excessively soft.
It must maintain the definition of its adjustment holes.
It must retain its shape around the buckle and keepers.
It must remain comfortable when exposed to heat, perspiration, and water.
The properties of the rubber therefore influence every part of the wearing experience.
Rubber B Is Not Silicone
The distinction between vulcanized rubber and silicone is particularly relevant within the luxury watch strap market.
The terms are sometimes used interchangeably by consumers, but they describe different materials.
Rubber B’s principal strap collections are made from vulcanized rubber rather than silicone.
This distinction matters because the physical behavior, density, tactile characteristics, finishing possibilities, and long-term performance of the materials can differ significantly.
For Rubber B, the rubber formulation is part of the product engineering itself.
The strap is developed to complement the requirements of a specific luxury watch rather than functioning as a generic silicone accessory produced in standard sizes.
Adjustment and Wrist Ergonomics
One of the defining characteristics of the Tang Buckle Series is conventional hole-based adjustment.
The wearer selects the opening that provides the desired circumference and secures the excess strap through the keeper system.
This simplicity offers several advantages.
There is no deployant clasp mechanism occupying a large section underneath the wrist.
The wearer can immediately understand how the strap is adjusted.
The closure remains compact.
The buckle position also allows the rubber to maintain continuous contact around a larger portion of the wrist.
However, achieving comfortable fit still requires careful strap design.
The location and spacing of the holes, strap length, taper, thickness, keeper positioning, and flexibility of the rubber all influence where the buckle ultimately rests.
A properly engineered tang-buckle strap must therefore be considered three-dimensionally.
It is not simply a flat object with holes punched through it.
It must curve naturally around the wrist.
The Tang Buckle Series and Rolex
Rolex sports watches represent some of the most recognizable applications of the Rubber B Tang Buckle Series.
Compatible configurations have been developed for multiple references across the brand’s professional and sports collections.
These include watches from families such as:
- Submariner;
- GMT-Master II;
- Cosmograph Daytona;
- Explorer;
- Explorer II;
- Sea-Dweller;
- Deepsea;
- Yacht-Master;
- Oyster Perpetual.
Each presents different design requirements.
The Daytona has a comparatively streamlined sports-watch profile.
The Submariner and GMT-Master II require a strap capable of visually supporting their substantial ceramic-bezel cases.
The Deepsea presents significantly greater case dimensions.
The Explorer family has its own lug and case proportions.
This diversity demonstrates why Rubber B does not approach Rolex straps as a single universal product category.
Compatibility is determined by specific watch architecture.
Rolex Submariner: Integrated Sport Architecture
The Rolex Submariner is perhaps the clearest demonstration of the Tang Buckle Series concept.
The Submariner was conceived as a professional diving watch, and modern references possess substantial case architecture and highly recognizable proportions.
Removing the Oyster bracelet significantly changes the appearance of the watch.
A model-specific Rubber B strap fills the visual space between the lugs and follows the case profile, helping the rubber appear as an intentional extension of the watch rather than an unrelated accessory.
The tang buckle then creates a more traditional strap configuration around the wrist.
This combination makes the Submariner a useful example of the central Tang Buckle philosophy:
precise case integration without dependence on the original deployant clasp.
Rolex GMT-Master II: Color and VulChromatic®
The GMT-Master II provides another important Tang Buckle application because color has become central to the identity of the collection.
Modern GMT-Master II references are frequently identified by their two-color ceramic bezels.
This creates an opportunity for the strap itself to interact with the watch’s color palette.
Rubber B’s VulChromatic® technology allows different colors of vulcanized rubber to coexist within a single strap construction.
Rather than applying a superficial painted color layer, VulChromatic® uses separately colored rubber masses combined during manufacturing.
The result allows the strap to introduce contrasting interior and exterior colors while maintaining rubber construction throughout.
On watches such as the GMT-Master II, this can create a visual relationship between the strap and the bezel without abandoning the technical characteristics of vulcanized rubber.
What Is VulChromatic®?
VulChromatic® is Rubber B’s proprietary approach to producing multi-color vulcanized rubber straps.
Two distinct rubber colors are incorporated into the construction rather than relying upon paint, adhesive films, or surface coatings to create the contrast.
This process opened another direction for the Tang Buckle Series.
Where earlier rubber straps were frequently monochromatic, VulChromatic® allowed the inside and outside of the strap to interact with the color identity of the watch itself.
Combinations such as black with blue, red, green, or other contrasting tones can complement bezel accents, dial details, or personal preference while retaining an integrated luxury-watch fit.
The technology demonstrates how Rubber B has continued developing the Tang Buckle platform rather than treating it as a static product.
Rolex Daytona: Classic Series or Tang Buckle?
The Rolex Cosmograph Daytona illustrates particularly well why both the Classic Series and Tang Buckle Series can coexist.
A Daytona owner who wants to retain a compatible original Rolex deployant clasp may prefer a Classic Series configuration designed around that hardware.
Another wearer may prefer to keep the original bracelet and clasp completely assembled while changing the watch to rubber.
For that owner, a Tang Buckle Series configuration creates a separate strap system.
The resulting aesthetic is also different.
The deployant configuration maintains a stronger connection to Rolex bracelet architecture.
The tang buckle provides a lighter, more traditional strap appearance.
The choice therefore involves more than functionality.
It influences the entire character of the watch on the wrist.
Tudor Black Bay 58: Traditional Proportions Meet Modern Rubber
The Tudor Black Bay 58 represents another particularly suitable Tang Buckle application.
The Black Bay 58 draws heavily from the proportions and design language of historical dive watches.
A traditional tang buckle therefore fits naturally within its aesthetic.
At the same time, the strap can incorporate modern Rubber B integration and Swiss-Made vulcanized rubber construction.
Selected Black Bay 58 configurations use an 18 mm Fine Tang Buckle manufactured from 316L stainless steel.
The combination creates an interesting contrast:
vintage-inspired watch proportions paired with contemporary rubber engineering.
This is an example of the Tang Buckle Series working not only as a practical closure system but also as part of the design language of the watch.
Beyond Rolex: Tudor, IWC, Omega and More
Although Rolex played a major role in the early development of integrated Rubber B products, the Tang Buckle concept extends beyond a single watch manufacturer.
Model-specific configurations have been developed for watches from manufacturers including Tudor, IWC, Omega, and others.
This expansion is important because each brand approaches case architecture differently.
An IWC pilot’s watch does not possess the same lug geometry as a Rolex Submariner.
A Tudor Black Bay does not share the same proportions as an Omega Speedmaster.
A successful integrated rubber strap must therefore account for those differences.
The broader Tang Buckle collection illustrates how the basic concept can be adapted while remaining consistent:
precision at the watch case, Swiss-Made vulcanized rubber around the wrist, and traditional buckle closure.
SwimSkin® and the Expansion of Tang Buckle Design
The Tang Buckle platform also created opportunities to move beyond the appearance of conventional smooth rubber.
Rubber B developed SwimSkin®, a vulcanized-rubber technology designed to reproduce the visual texture of materials traditionally associated with luxury watch straps.
Depending on the application, SwimSkin® can produce an appearance inspired by alligator leather, ballistic textile, or other luxury strap textures while retaining rubber construction.
This becomes particularly interesting with a tang buckle.
Historically, traditional leather straps have almost always been associated with pin-buckle closures.
SwimSkin® can reproduce aspects of that visual language while using vulcanized rubber instead of animal leather.
A watch may therefore retain the sophisticated appearance associated with a traditional textured strap while gaining the water-friendly characteristics of rubber.
The Tang Buckle Series becomes the natural closure architecture for this design philosophy.
Traditional Closure, Contemporary Material
This relationship between traditional design and modern material is central to understanding the Tang Buckle Series.
The tang buckle itself is not a new invention.
Its value comes precisely from its simplicity and historical familiarity.
Rubber B did not attempt to replace that principle.
Instead, the innovation occurs around it.
The rubber formulation is modern.
The model-specific integration is modern.
The internal structural engineering is modern.
VulChromatic® is modern.
SwimSkin® is modern.
The traditional closure becomes the anchor around which these technologies operate.
Why Model-Specific Fit Matters
Many rubber watch straps are produced according to standardized lug widths.
A manufacturer may produce one 20 mm strap, for example, and market it as compatible with dozens or hundreds of watches that share approximately the same distance between their lugs.
This approach can be practical, but it treats compatibility largely as a two-dimensional measurement.
Luxury sports watches are not two-dimensional objects.
The curvature of the case, position of the spring bars, depth of the lugs, case thickness, bezel diameter, and shape of the case flank can all influence how a strap meets the watch.
Rubber B’s model-specific philosophy considers these variables during product development.
This is why a Rubber B Tang Buckle strap designed for a particular Submariner reference should not automatically be assumed to fit another watch simply because both share a similar nominal lug width.
Compatibility depends upon the complete engineering relationship between strap and watch.
An Integrated Strap Is More Than a Curved End
The term “integrated” is widely used throughout the watch-accessory market.
Visually, many products may appear to sit flush against a case.
But integration involves more than molding a curved section of rubber.
The interface must control movement.
The strap must interact properly with the spring bars.
The shape must correspond with the watch case.
The material around the attachment point must support repeated movement and load.
The strap must transition naturally from the rigid metal watch head into flexible rubber.
This requires engineering at a scale that may not immediately be visible in photographs.
The most important elements of an integrated strap are often hidden inside the product.
Preserving the Original Bracelet as a Complete Assembly
One practical characteristic of the Tang Buckle Series deserves particular attention from collectors.
When a compatible Classic Series configuration requires the original deployant clasp, the clasp must generally become part of the rubber strap system.
The Tang Buckle Series can remove that requirement.
The original bracelet and clasp may therefore remain together as a complete assembly while the watch is fitted to the separate Rubber B strap and buckle.
For owners who rotate between configurations, this can make storage and future reinstallation more straightforward.
It also allows the original bracelet to remain in its intended configuration when not being worn.
This should not be confused with a claim about monetary value or resale value.
It is simply a different approach to maintaining and using original watch components.
Water, Heat and Active Use
Rubber has long been associated with sports and dive watches because of its suitability for active environments.
A properly engineered vulcanized rubber strap is not dependent upon absorbent natural fibers or leather.
This makes the Tang Buckle Series particularly appropriate for watches frequently exposed to:
- swimming;
- boating;
- humid climates;
- perspiration;
- travel;
- exercise;
- everyday outdoor wear.
The buckle and rubber must work together under these conditions.
The 316L stainless-steel hardware provides corrosion resistance, while the vulcanized rubber is intended to retain its functional properties during repeated environmental exposure.
This functional relationship is particularly appropriate for professional sports-watch designs originally conceived for demanding conditions.
The Evolution of the Tang Buckle Series
The Tang Buckle Series has existed within the Rubber B catalog for many years and has been documented externally in watch-enthusiast reviews dating back at least to the middle of the 2010s.
Over time, the concept has expanded beyond straightforward monochromatic integrated rubber straps.
Developments have included:
- specialized buckle proportions;
- additional luxury watch manufacturers;
- VulChromatic® dual-color construction;
- SwimSkin® textures;
- new case integrations;
- broader color palettes;
- continued refinement of strap geometry.
Rather than remaining a single product, Tang Buckle became a platform through which multiple Rubber B technologies could be applied.
This evolution mirrors a broader shift within luxury watch collecting.
Rubber is no longer treated exclusively as a utilitarian material for inexpensive sports watches.
It has become an established component of contemporary haute horlogerie and luxury sports-watch design.
Rubber B and the Development of Integrated Rubber Straps
Rubber B was established around the idea that a rubber strap for a luxury watch should be designed specifically for that watch.
That principle helped distinguish the brand from universal aftermarket straps.
The strap became an engineered component rather than a generic accessory.
The Classic Series demonstrates this philosophy through integration with compatible original deployant hardware.
The Tang Buckle Series demonstrates it differently.
It preserves precision at the watch case while creating an independent closure system.
Later technologies such as VulChromatic®, SwimSkin®, and additional Rubber B strap architectures expanded upon the same foundation.
Each represents another answer to the same question:
How should a modern luxury watch interact with rubber?
Tang Buckle Series or Classic Series: Which One Should Be Chosen?
The appropriate configuration depends on the watch, available compatibility, and the desired wearing experience.
A wearer who wants to retain the compatible original manufacturer deployant clasp may prefer the Classic Series.
A wearer who prefers a traditional pin-buckle closure or who wants to keep the original bracelet and clasp assembled may prefer the Tang Buckle Series.
The visual character also differs.
Classic Series configurations generally retain more of the original clasp architecture.
Tang Buckle configurations place greater visual emphasis on the rubber itself and use a comparatively compact traditional closure.
Neither approach changes the fundamental importance of proper compatibility.
Rubber B products are engineered for specific watch references, and the appropriate strap should always be selected according to the exact model.
Frequently Asked Questions About the Rubber B Tang Buckle Series
What is the Rubber B Tang Buckle Series?
The Rubber B Tang Buckle Series is a collection of Swiss-Made vulcanized rubber straps designed for compatible luxury watch references and configured with a traditional tang-style buckle rather than relying upon an original deployant clasp.
Many models also incorporate Rubber B’s proprietary Blocked Integration™ technology at the watch case.
What is a tang buckle on a watch?
A tang buckle is a traditional watch-strap closure consisting of a metal frame and a movable pin. The pin passes through one of several holes in the strap to adjust the circumference around the wrist.
It is similar in principle to the buckle used on many traditional leather watch straps.
What is the difference between the Rubber B Classic Series and Tang Buckle Series?

Similar lug width alone does not guarantee compatibility.
The exact Rolex model and reference should always be confirmed before selecting a strap.
Can the original Rolex bracelet remain together when using a Tang Buckle Series strap?
On configurations where the Rubber B strap uses its own tang buckle, the original bracelet and deployant clasp do not need to become part of the rubber strap assembly.
This can allow the factory bracelet and clasp to remain stored together as a complete unit.
What is VulChromatic®?
VulChromatic® is a Rubber B technology used to create multi-color vulcanized rubber straps.
Different colored rubber masses are incorporated into the strap construction rather than relying upon superficial paint or adhesive color layers.
What is SwimSkin®?
SwimSkin® is a Rubber B vulcanized-rubber technology designed to reproduce the appearance and texture of materials traditionally associated with luxury straps, including alligator-style and textile-inspired surfaces.
The visual texture is created while retaining rubber construction.
Can a Rubber B Tang Buckle strap be worn in water?
Vulcanized rubber is particularly suitable for aquatic and humid environments, and the Tang Buckle Series is frequently paired with sports and dive watches.
Owners should nevertheless follow the water-resistance and usage recommendations of the watch manufacturer and verify the condition and installation of the strap before aquatic activity.
Which watches are available with Rubber B Tang Buckle straps?
Tang Buckle configurations have been developed for numerous luxury watches, including selected references from Rolex, Tudor, IWC, Omega, and other manufacturers.
Availability and compatibility vary according to the exact watch reference.
A Traditional Buckle Reengineered Around the Modern Luxury Watch
The enduring strength of the tang buckle is its simplicity.
It requires no complicated explanation.
For generations, watch owners have understood intuitively how the mechanism works.
Rubber B’s contribution was not to reinvent that principle.
It was to reconsider everything surrounding it.
The connection between the strap and the watch case became model-specific.
The rubber became a Swiss-Made engineered material.
The proportions became calibrated to individual luxury sports watches.
Blocked Integration™ addressed the relationship between strap and case.
VulChromatic® introduced color within the rubber construction itself.
SwimSkin® expanded the visual vocabulary of vulcanized rubber.
Specialized buckle designs allowed the architecture to adapt to watches with different dimensions and personalities.
The result is the Rubber B Tang Buckle Series: a traditional closure transformed into part of a complete contemporary luxury-watch strap system.
For a watch collector, the visible buckle may be the simplest part of the design.
The engineering that connects it to the watch is where the story truly begins.
