Genuine Alligator Leather Watch Strap in Black on Jet Black Rubber Base

There are many genuine leather watch straps available today, but none with the luxury and comfort of the Structure Series straps by Rubber B. With genuine leather seamlessly fused onto a vulcanized rubber base, our straps are built to be worn daily. Combining the characteristics of rubber and leather on one strap allows the wearer to enjoy their luxury timepiece in any environment.

Anyone with an active lifestyle knows what happens when you perspire while wearing a standard leather watch strap. The moisture penetrates the leather, causing odors and eventually cracking of the skin. Many leather watchbands have cardboard filler pads that deform after contact with elements of daily wear. Our solution for this was to create a strap that benefits from the properties of vulcanized rubber but still has the appeal of a classic leather strap.

Our Structure Series straps are designed to fit timepieces from any brand based on the space between the lugs. If your watch has a lug width of 18mm, 20mm or 22mm, you can browse our selection of straps designed to fit your timepiece in our e-Boutique. In addition to the Jet Black alligator leather strap shown above, we offer straps in Cognac and Saddle Brown. We also offer a Jet Black strap with a Red Devil rubber base, perfect for those with a sporty sense of style.

You can shop all of our straps, including Swiss made rubber straps micro-calibrated for Rolex, Panerai and Patek Philippe, 24/7 at We ship anywhere in the world within 24-48 hours of order placement, with expedited shipping available.

Patek Philippe is the maker of some of the finest timepieces on the market today, with a rich history of horological excellence. Their Nautilus models are instantly recognizable with their porthole-shaped bezel that is hand-polished by experts in Swiss watchmaking. In order to create a rubber strap configuration befitting of such mastery, much attention has to be paid to the finer details so that the integrity of the original piece is maintained.

At Rubber B, we are the makers of the ultimate rubber strap for Patek Philippe. Manufactured in Switzerland by leaders in the watchmaking industry, our straps are made from the highest quality vulcanized rubber available. We micro-calibrate each strap using ‘blocked integration’ engineering for a flush, motionless mount onto the watch case. No detail is overlooked in their execution, including the textured design detail that follows the lines of the case down the middle of the strap.

The colors chosen for our Patek Philippe collection compliment the classic aesthetic of the models they are designed to fit. The photo above shows straps in Espresso Brown and Jet Black, both popular selections. We also offer Chocolate Brown and Charcoal Gray straps that match both yellow and white gold configurations beautifully. For those who prefer to accentuate their nautical aesthetic, we offer Arctic White and Navy Blue straps that add a marine color scheme to the Nautilus models.

Our straps incorporate the deployant buckle that comes on the original leather strap (not compatible with models on metal bracelets). This creates a rubber strap configuration that is both comfortable and secure, with a fully integrated design. Our straps ship anywhere in the world within 24-48 hours of order placement, with expedited shipping available. Visit to browse our entire collection of straps for Patek Philippe timepieces.

Tudor North Flag Reference 91210N

One of the first Tudor models to be equipped with a movement manufactured completely in-house by the watchmaker, the North Flag is a tool watch for the modern adventurer. This stainless steel model is at home in the Arctic Circle, where modern electronics may not be suited to assist explorers and scientists. The self-winding mechanical movement with bidirectional rotor system of the North Flag offers power while the luminescence of the hands and hour markers ensure legibility even in the darkness of winter.

The 40 mm case of the North Flag is made of steel with a satin finish and open case back with a sapphire crystal. It features a double bezel in steel and matt black and a steel winding crown with the Tudor logo in relief. The black dial features Arabic numerals at 12 and 6 o’clock, a date displayed through an aperture at 3 o’clock and a power reserve indicator at 9 o’clock. Its MT5621 movement features a 70 hour power reserve and a frequency of 28,800 beats per hour.

One of the features of the North Flag that differentiates it from other models in the Tudor line is the arrowhead-shaped hour hand. It replaces the snowflake-shaped hour hand that appears on other Tudor models, like the Pelagos and Black Bay. It also has a unique yellow-colored seconds hand that  matches the power reserve indicator, minute scale and the stitching on the black leather strap that is also available on this model.

We are soon to add a collection of Swiss-made vulcanized rubber straps designed for Tudor models to our e-Boutique at Click here to sign up for a notification when these unique luxury straps will be available for purchase.
