Oyster Perpetual and Datejust 31

The Rolex Oyster Perpetual and Datejust models have a tremendous selection of options in the 31mm size.  On the bezel you can opt for a domed, or fluted bezel.  The bezel can also be set with diamonds or have a domed look with diamonds set inside.  There is a two-tone “Rolesor” model made from Oystersteel and Everose gold, or you could opt for a solid yellow, white or pink gold option.

The bracelet options come with either Oyster or Jubilee.  The dial has a tremendous selection including hour markers set in diamond, gold hour markers in roman numeral or classic dash markers filled with luminescence. The actual dial can be a mother-of-pearl or choose from one of the many colors of the Rolex palette.

Although the 31mm is identified as a size intended for a “lady,” the feel and thickness of the timepiece makes it perfect for anyone who wants a lighter and smaller size Rolex.  These models are powered by the high precision caliber 2235 which sports a 48-hour power reserve.  The 2235 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC).

The winding crown has a screw-down, Twinlock double waterproofness system which supports a water-resistance to 330 feet.  The crystal is a scratch-resistant sapphire.  For the datejust models, the cyclops lens is embedded in the crystal over the date at 3 o’clock, to improve the date aperture visibility.

Rolex Cellini Time Reference 50505

The Rolex Cellini Time reference 50505 is an elegant timepiece which combines the Rolex standards with the classic tradition of the round shaped timepiece.  The reference 50505 is designed with pure 18 ct Everose gold which was developed by Rolex in 2005.  The hour hand, minute hand and the hour marker appliques are designed with a double-edged sword look – also in Everose gold.

The hour appliques are split in half with the inner ring indicating minutes or seconds notation depending on which hand you are referring to.  The sole exception is at 12 o’clock, where double appliques represent 0, 60 (minutes and seconds) and 12 (hours) on the dial, and there is no separation as there is on hour markers 1 through 11.  The case is 39 mm with a polished finish.  The Cellini has a double bezel which is domed on the inside and fluted on the outside.  The screw-down winding crown has the traditional Rolex emblem on it.  The timepiece is covered by a domed sapphire crystal.  The traditional white dial beautifully offsets the pink gold and black markings and text.  The Cellini name is uniquely inscribed in cursive on the white dial.

The Cellini is powered by a 31 ruby-clad caliber 3132 which has a bidirectional self-winding perpetual rotor, giving it approximately 48 hours of power reserve.  The reference 50505 has a water-resistance to 165 feet.  The timepiece is fitted with a stitched alligator leather strap with large scales and an 18 ct gold buckle which matches the Everose gold of the watch case.  While many Rolex timepieces serve dual purposes, the Cellini is primarily a dress watch which exudes an air of nobility.

The Short History of Vulcanized Rubber Bracelet Use in Horology

Vulcanized Rubber Band on Rolex Yachtmaster II

Rubber has been around for quite some time.  However, the early excitement of utilizing rubber was tainted by the issues of pure rubber – it would freeze and crack in the winter, and it would melt and become sticky when exposed to the summer heat.  Nathaniel Hayword and Friedrich Ludersdorf discovered that by adding sulfur to pure rubber, it would eliminate stickiness.

However, in 1839, Charles Goodyear, famously linked to the name well-known Goodyear Tire and Rubber Co., elaborated on Hayword’s discovery by developing the vulcanization process, where rubber could be heated by a stove and charred, producing a perfectly cured leather-like substance (yet, in many ways, superior to leather).  The word “vulcanize” comes from the Roman god of fire, Vulcan.  By heating rubber to a specific temperature and then removing it from the heat at the exact right point in time, the rubber would become vulcanized.

The resulting vulcanized rubber substance became extremely strong, weatherproof, and elastic.  Sulfur is an accelerator, which combines and creates bridges in the molecules, allowing natural rubber to be transformed into a substance which can be expertly molded while keeping its shape – free of swelling or melting in spite of hot or cold temperatures. Later enhancements to vulcanized rubber include adding carbon black or zinc oxide to retard deterioration caused by oxygen and ozone.

Vulcanized rubber has several advantages over most any substance in the world.  It has excellent strength and resilience and easily returns to its original intended shape after bending.  It resists wear and tear and oxidation.  It repels fats, oils and other solvents, while also limiting water absorption.  It has a wide temperature range making it flexible and reliable between −80 °C to +250 °C and won’t break down until it hits temperatures above 350 °C.

The watchmaking industry first began adding rubber bands to their timepieces in the 1950’s.  Rolex, Tudor, IWC and Blancpain were some of the early timepieces found with rubber bracelets.  However, it wasn’t until the 1960’s that the use of rubber bands became mainstream, largely due to its usefulness on diver and sports watches.  It’s weather and water proof qualities were perfect for watch owners with an active lifestyle.  The Swiss watchmaking industry adopted and perfected the use of vulcanized rubber bands as an extension to its artistry.  Bands are designed with many colors, even bright colors like orange, red and yellow – enhancing the palette of what is possible.

Vulcanized rubber bands have exceptional properties that make them superior bracelets for fine timepieces.  They are lightweight, compared to steel or gold watchbands.  Not only are they waterproof in both fresh and saltwater, but they feel lighter when being worn in water – making them a perfect complement to a diver or nautical timepiece.  They are durable and resistant to the effects of sunlight and radiation and they do not rust.  They clean easily, are non-toxic and non-allergenic.

Rubber bands are easy to fit and adjust and generally can be worn by both men and women of any wrist size, universally.  They are comfortable to wear and can be designed to fit the deployant buckle of the manufacturer.  Vulcanized rubber bands are scratch resistant and are a low-cost (and in many ways a superior) alternative to steel and gold bands made by the manufacturer.

Probably the most important feature of vulcanized rubber bands is the stylish qualities.  Vulcanized rubber can be forged into millions of beautiful designs and patterns.  They can utilize the blues, blacks, and browns of the boardroom, or the fun colors of spring and summer, giving each timepiece an endless supply of stylish adaptability.  Since it is easy to change a band, a timepiece owner might have a collection of different color rubber bands and be able to adapt the look of their timepiece in minutes.

Rubber B has expanded upon the Swiss Vulcanized Rubber bracelet tradition by developing several enhancements of their own.  Rubber B developed “Blocked Integration” which creates a tight, motionless, rotationless, and gap-free mount to the watch head.  Rubber B has strengthened their straps by infusing carbon fiber molecules into the vulcanized rubber – thus reducing stress while maintaining supple, flexible comfort around the wearer’s wrist. Rubber B has combined industrial strength Velcro Alfatex and Titanium-Enforced loops to create unique rubber bands utilizing a powerful Velcro clasp.  For more information, visit our product pages for a wide variety of vulcanized rubber bracelets made for an active and stylish lifestyle.

Rubber B has several blue-colored bands, solid blue, navy blue (see the Panerai Luminor Submersible below), black straps with blue stripes down the middle (see the Panerai Luminor 44mm below), or two-tone straps with black on top and blue underneath (see the Tudor Heritage Black Bay below).   Rubber B utilizes both a Navy Blue and a Pacific Blue which is a lighter and brighter shade to add interest and to match the luminescent colorings of the timepiece’s components – such as the bezel and hour/minute hands on the Rolex Yachtmaster II.

Another area that Rubber B excels in is in its unique way of attaching to the timepiece’s case.  Many of the bands are engineered with “Blocked Integration” which creates a flawless, motionless flush mount to the case.  This is visible on the Panerai, Tudor and Rolex models.

Rubber B has implemented the blue coloring differently in the Panerai Luminor Marina above and the Tudor Heritage below.  Both utilize a black band with attention drawing pacific blue coloring, but on the bracelet for Panerai, Rubber B utilizes a racing stripe down the center.  The Tudor, on the other hand, has an underlying blue which extends from the case to the buckle and lays against the wrist of the wearer.  The blue peeks through on the end of the band where the buckle is attached.

Rubber B’s Huge Selection of Alternative Bands for the Rolex Milgauss

Rolex Milgauss

Rolex Milgauss

The Rolex Milgauss was the first timepiece of its kind.  Created in 1956 for scientists at the European Organization for Nuclear Research (CERN) in Geneva, the Rolex Milgauss was designed to work without being affected by magnetic fields of 50 to 100 gauss – common for scientists at the CERN laboratory.  The word “Mille” is French for 1000, and Rolex set as its goal to create a timepiece with protection from magnetic interference up to 1000 gauss.

At first, Rolex created a shield inside the Oyster case made of ferromagnetic alloys to protect the movement–an early “Faraday Cage”.  In addition, the stainless steel used on the case is slightly thicker than other Rolex models.  This was quite effective and achieved the goal of reducing magnetic interference on the Milgauss.

However, more recently Rolex has adapted paramagnetic materials, such as the Parachrom hairspring, to dispel interference.  In a timepiece the oscillator is what keeps consistent time.  Rolex developed an oscillator hairspring from niobium and zirconium, which are insensitive to magnetic fields and 10 times more resistant to shocks.  So, not only is the resulting Milgauss resistant to magnetic fields, it is also highly shock resistant.

The Milgauss Ref 116400 features a 40 mm Oystersteel case and steel Oyster bracelet.  It has a twinlock double waterproofness system supports a diving depth of 330 feet.  The white dial has highly luminescent hour markers and minute and hour hands that create a long-lasting orange luminescence in a dark lab setting or diving to murky depths.

The caliber 3131 movement has a power reserve of 48 hours.  Most notably the dial has a bright orange seconds hand that is shaped like a lightning bolt with an arrow at the tip.  Around the dial are markings (for the seconds hand) at 5-second intervals, starting at 5 and ending at 60.  The newest version of the Milgauss has a lime sapphire crystal inside of the polished steel bezel–creating light reflection and preserving optimal legibility.  This is a new enhancement that only adds to the history of “firsts” in the Rolex Milgauss design history.

Rubber B has developed more custom watchbands for the Rolex Milgauss than any other company in the world.  To begin with, Rubber B has developed three types of band closures for the Milgauss – supporting the original Rolex clasp, utilizing a Rubber B 316L Stainless Steel Tang Buckle, or the Industrial Strength Velcro Closure.  In all, Rubber B has 17 custom variations for the Rolex Milgauss and a stunning selection of colors to complement the colorful Milgauss – including bright orange or white bands which match the Milgauss dial coloring.

All of the bands designed for the Rolex Milgauss by Rubber B incorporate Blocked Integration for a tight motionless fit to the case.  The Rubber B alternative bracelets for the Rolex Milgauss are made in Switzerland of pure vulcanized rubber –utilizing NO coating, blends or bonding.

Keeping with the tradition of invention in the Milgauss line, Rubber B has invented a unique Velcro series of bands which utilize a Titanium insert in the attachment loop, to retain optimal strength and performance.  These Velcro clasp watch straps are tortion-tested for extreme strength and security.  For more information on Rubber B’s complete lineup of bracelets for the Rolex Milgauss go to our page here.
