Complete Guide to RubberB Rubber Straps for Rolex
The ultimate Swiss rubber strap — technology, materials, and compatibility deciphered for each Rolex model.
At MisterChrono Paris, we assist watch enthusiasts every day in choosing their strap. Among all the brands we offer in our boutique, RubberB holds a special place. It's not just another rubber strap — it's the result of precise Swiss engineering applied to a watch accessory, designed specifically for Rolex watches.
This comprehensive guide explains everything you need to know about RubberB straps: the material, exclusive technologies, the different series available, and compatibility with each Rolex reference we offer in our store.
The material: 100% pure vulcanized rubber
The first element that distinguishes RubberB from its competitors is the intrinsic quality of its raw material. Every RubberB strap is made from 100% pure vulcanized rubber — no surface coating, no material blends, no glue, and no artificial chemical bonding.
This "pure rubber" approach is significant. Cheap rubber straps are often made from silicone or synthetic blends, sometimes covered with a coating that flakes off over time. With RubberB, vulcanized rubber is worked through and through: there's nothing to peel off, nothing to alter on the surface.
Concrete results:
- The strap does not lose its color over time, even after prolonged exposure to sun or salt water.
- It does not retain dust — a natural property of pure vulcanized rubber.
- It complies with all health standards: non-toxic, non-marking, non-allergenic — exceeding FDA and BVGG specifications.
- It retains its shape regardless of temperature or usage conditions.
Each RubberB strap is handcrafted and finished in Switzerland by professionals who apply the same quality standards as the luxury watch industry.
Exclusive RubberB Technologies
Blocked Integration — perfect integration with the case
Blocked Integration technology is at the heart of RubberB engineering. It involves integrating micro-calibrated solid inserts directly into the strap's structure, which precisely fit the lugs of your Rolex watch.
Practically, the strap does not "hang" from the lugs — it is recessed flush, meaning perfectly even and without play. The visual result is that of an original integrated strap, as if Rolex itself had designed this rubber strap.
This is why each RubberB strap is developed and calibrated reference by reference — there is no "universal for Rolex" RubberB strap. Each model (Submariner ceramic, Submariner non-ceramic, GMT-Master II, Daytona, etc.) has its own micro-calibrated version.
VulChromatic — two-tone fusion
VulChromatic technology is an exclusive RubberB innovation for two-tone straps. It allows two shades of vulcanized rubber to be fused into a single strap, without visible joints, gluing, or stitching.
This technology is particularly popular on the GMT-Master II: the two-tone black/red ("Batman") or blue/black ("Batman") versions are perfectly echoed in a rubber strap with the same shades, fused by VulChromatic.
RubberB's signature "T" design is present on all straps in the range, subtly recalling the brand's identity without ostentation.
RubberB Series available at MisterChrono
Classic Series
The most versatile series. The Classic Series strap fits all wrists, from XXS to XL (14 to 21 cm), and mounts directly onto the original Rolex Oyster clasp. It is the ideal series for a first RubberB experience: immediate comfort, perfect integration, ease of fitting.
Couture Series
RubberB's premium series. It features Gore Tenara thread stitching — the same thread used in the most demanding outdoor equipment, rot-proof and UV-resistant. This high-end finishing detail transforms the strap into a true luxury sports leather good.
Tang Buckle Series
Designed for those who want a RubberB strap with an independent tang buckle rather than the original Oyster clasp. The buckle is made of 316L stainless steel — the same surgical grade used by Rolex for its cases. Ideal for wearers who want a different fastening system or who own multiple watch models.
Rubber Cuff Series
The most original series. The Rubber Cuff strap visually and tactilely mimics a soft textile (like a fine twill) — but it's 100% rubber. Waterproof, ultra-light, available in black, blue, and green. Particularly popular on the Rolex Milgauss.
Compatibility with Rolex models
RubberB offers a specifically calibrated strap for each Rolex reference. Here are the models available at MisterChrono:

Important: For the Submariner, RubberB offers distinct versions depending on the generation of your watch (pre-2010, 2010-2019, 2020 to present). Compatibility with the Glidelock clasp (ceramic Submariner) is also specific. If in doubt, our advisors at our Paris boutique will guide you to identify the exact reference of your watch.
How to install a RubberB strap on your Rolex?
The RubberB strap mounts directly onto your Rolex Oyster clasp — without using the additional links from the original bracelet. This is a simple installation that you can perform at home with a quality spring bar tool.
- Remove the spring bars from the current strap using a spring bar tool.
- Insert the RubberB strap inserts into the lugs of your Rolex case.
- Attach the spring bars to secure the strap.
- Attach your original Oyster clasp to the end of the strap.
If you have never changed your Rolex strap, or if you prefer to entrust this operation to a professional, our team at the Paris boutique offers free installation for any RubberB strap purchased from MisterChrono.
Maintenance and durability
One of the great advantages of RubberB vulcanized rubber is its ease of maintenance:
- After contact with seawater or chlorinated water: rinse with fresh water and dry with a microfiber cloth.
- Regular cleaning: a slightly damp cloth and mild soap are sufficient. Any residue can be easily removed.
- Sunscreen: avoid prolonged contact. Rinse after exposure.
- Storage: keep away from extreme heat and direct light for long-term storage.
