FKM vs. Vulcanized Rubber Straps: Which One Holds Up Better in Singapore and Hong Kong?
Strap Expertise — by Pierre-Yves FKM vs. Vulcanized Rubber Straps: Which Resists Singapore and Hong Kong's Humidity Better? A question our clients regularly ask us from our Parisian boutique on Rue Danielle Casanova—and one whose answer deserves much more than a simple sales pitch. Among watch enthusiasts who frequently travel to Southeast Asia and those who reside in Singapore or Hong Kong for part of the year, the question persistently arises: which type of rubber strap is truly best suited for an ultra-humid tropical climate? FKM or vulcanized rubber? The debate is serious, the differences are real, and the stakes for your valuable watches are considerable. At MisterChrono, we select our straps with the same exacting standards you apply to your timepieces. In this article, Pierre-Yves offers an in-depth analysis, without compromise or unnecessary jargon, to help you make the most informed choice possible—whether you are in Paris or heading for a week of 90% humidity in the tropics. Understanding the two materials: FKM and vulcanized rubber FKM: high technology on your wrist FKM—for Fluoroelastomer—is a fluorinated elastomer originally developed for the most demanding industrial applications: aerospace, chemistry, petrochemicals. Rolex popularized this material in watchmaking under the commercial name Oysterflex, but today, many brands and aftermarket strap manufacturers offer very high-quality FKM options. Its technical characteristics are impressive: Thermal resistance from -20 °C to +200 °C Exceptional resistance to oils, solvents, UV, and chemical agents Almost total inertness to perspiration and sea salt Estimated lifespan of over 10 years under normal use conditions Smooth, non-porous surface, easy to disinfect In terms of feel, FKM is slightly stiffer than other rubbers, but it perfectly molds to the wrist after a few days of wear. Its distinctive texture—soft yet firm—is instantly recognizable. Vulcanized rubber: the timeless classic Vulcanization is a chemical process invented by Charles Goodyear in the 19th century, which involves cross-linking the polymer chains of natural or synthetic rubber using sulfur, heat, and pressure. The result: a material much more resistant, elastic, and durable than raw rubber. In watchmaking, vulcanized rubber has been used for decades by prestigious houses. It offers several notable advantages: Flexibility and natural comfort from the first wear Elegant matte aesthetic, suitable for both sports watches and dress models Good resistance to fresh and salt water Wide range of finishes (smooth, grained, textured, perforated) Generally more affordable than pure FKM However, it remains more susceptible to body oils and intense perspiration in the long term, and its durability against prolonged UV exposure is slightly lower than that of FKM. Singapore and Hong Kong: extraordinary climatic conditions To understand why this FKM vs. vulcanized rubber debate takes on a particular dimension in tropical Asia, one must first gauge the climatic difference with a city like Paris. In Paris, the average relative humidity fluctuates between 65% and 80% depending on the season. This is already an environment that some leather straps struggle to endure over time. In Singapore, relative humidity constantly hovers around 80% to 90%, with peaks of 100% during daily downpours—and this, 365 days a year. In Hong Kong, the months of May to September combine tropical heat, extreme humidity, and repeated typhoons. Under these conditions, here's what concretely happens with an unsuitable strap: An untreated leather strap can degrade in a few weeks A NATO or textile nylon strap absorbs sweat and bacteria Poor quality rubber softens, discolors, and cracks Even poorly qualified stainless steel can show signs of oxidation Detailed comparison for tropical conditions Criterion FKM Vulcanized Rubber Sweat resistance ⭐⭐⭐⭐⭐ Excellent ⭐⭐⭐⭐ Very Good UV and heat resistance ⭐⭐⭐⭐⭐ Superior ⭐⭐⭐⭐ Good Wrist comfort upon wearing ⭐⭐⭐⭐ Very Good ⭐⭐⭐⭐⭐ Excellent Longevity in humid climates ⭐⭐⭐⭐⭐ 10 years+ ⭐⭐⭐⭐ 5–8 years Ease of cleaning ⭐⭐⭐⭐⭐ Very Easy ⭐⭐⭐⭐⭐ Very Easy Value for money ⭐⭐⭐⭐ Investment ⭐⭐⭐⭐⭐ Excellent Luxury watch compatibility ⭐⭐⭐⭐⭐ Perfect ⭐⭐⭐⭐⭐ Perfect Note: this table represents general trends. The specific manufacturing quality of each strap remains the determining factor—which is why MisterChrono's selection makes no compromises on this point. What we recommend at MisterChrono The question isn't "FKM or vulcanized?" but rather "for what use, in what context, with what watch?". This is always the answer we give to our clients who visit our Parisian boutique at 23 rue Danielle Casanova, and it is the philosophy we uphold at MisterChrono. Opt for FKM if… You travel regularly to Singapore, Hong Kong, or any country with high tropical humidity You wear your watch continuously, including during sports, with significant perspiration Your watch is a significant investment, and you want a strap with the same lifespan You seek maximum resistance to chemical agents (chlorinated pools, seawater, sunscreens) You appreciate minimal maintenance: a simple rinse with lukewarm water is sufficient Opt for vulcanized rubber if… You seek immediate comfort, with no break-in period You wish to vary colors and textures more frequently Your wear is primarily in Europe with occasional tropical getaways You want to combine sporty style with a more controlled budget You collect straps and prefer several options to a single premium strap Pierre-Yves' care tips Whether you have chosen an FKM strap or a vulcanized rubber strap, a few simple gestures can significantly extend their lifespan, even after an intensive stay in the tropics: Rinse your strap with lukewarm fresh water after each exposure to the sea or pool Avoid cleaning products containing organic solvents (acetone, white spirit): they degrade polymers A slightly damp microfiber cloth is sufficient for daily cleaning Store your straps away from direct UV and heat sources above 50 °C For FKM straps, a light cosmetic-grade talc can prevent a "sticky" effect in high heat Regularly inspect the buckles and fastening holes: this is often where premature wear begins Why this debate is particularly relevant for Franco-Asian travelers France maintains strong economic and cultural ties with Singapore and Hong Kong. Many of our Parisian clients are professionals or expatriates who regularly navigate between these two worlds: one Monday in Paris in a suit, one Thursday in Singapore in a light shirt under 32 °C and 85% humidity. In this context, a watch strap is no longer a simple aesthetic accessory—it is a piece of equipment that must perform in radically different environments. And a valuable watch deserves a strap that doesn't let it down. It is precisely to address this reality that our team at 23 rue Danielle Casanova, a stone's throw from Place Vendôme, selects each strap with attention not only to aesthetics but also to material performance under varied and demanding conditions of use. If you're visiting the boutique soon, don't hesitate to mention your destination or lifestyle: we adapt our recommendations to your specific context, as we have done since our opening. The final word: quality trumps material A low-end FKM strap will perform worse than a high-end vulcanized rubber one. And vice versa. The FKM vs. vulcanized distinction is a valuable indication, but it does not replace judgment on the intrinsic quality of the product: material density, buckle quality, precision of perforations, consistency of color throughout. At MisterChrono, we only list straps that have passed our demanding specifications. Every model available on our website has been physically evaluated by our team before being offered to our customers.

Expert Guide · Published by Pierre-Yves · MisterChrono Paris Polywatch and Cape Cod: The Complete Guide to Polishing Watch Glass and Case Two essential products, two distinct uses. How to use Polywatch for glass scratches and Cape Cod to restore the shine of your watch's steel — step-by-step instructions. Your watch bears the marks of time. A fine scratch on the glass, a case that has lost its original luster, a steel bracelet marked by everyday micro-scratches. The good news: most of these imperfections can be corrected at home, in a few minutes, with two professional products that we have been recommending to our customers at MisterChrono Paris for years — Polywatch and Cape Cod cloths. This comprehensive guide explains what each product does, what it is intended for, and most importantly, how to use them correctly to achieve a professional result without risking damage to your watch. Polywatch vs Cape Cod: What's the Difference? First and foremost, understand that these are two complementary products, not interchangeable. Confusing them can damage your watch. Criterion Polywatch Cape Cod Form Paste in a tube Impregnated cloths Main Use Scratches on acrylic glass (Plexi) Micro-scratches on metals (steel, gold) Action Principle Fine abrasion (micro-particles) Chemical action + gentle abrasion Compatible Surfaces Acrylic / plexi only (standard version) Stainless steel, gold, silver, brass Prohibited Surfaces Sapphire, mineral glass, coated surfaces Glass, PVD, DLC, brushed finishes Golden Rule: Polywatch for acrylic glass, Cape Cod for metal. Never reverse — Polywatch abrades too finely for metal, and Cape Cod contains potentially aggressive chemical compounds for gaskets and glass. Polywatch: The Complete User Guide What exactly is Polywatch? Polywatch is a polishing paste manufactured in Germany, specifically formulated for acrylic watch crystals (Plexiglas / Hesalite). It contains abrasive micro-particles that remove a thin layer of plastic to smooth scratches and restore the transparency of the glass. Polywatch comes in two versions: Polywatch Plastic (red tube): for acrylic crystals (Plexiglas, Hesalite). This is the most common version. Polywatch Glass (blue kit): for mineral crystals. Warning: not suitable for sapphire crystals. Affected Watches Many iconic watches use an acrylic crystal that scratches easily but can be polished just as easily with Polywatch: Omega Speedmaster Professional "Moonwatch" (original Hesalite crystal) Vintage Rolex (mostly pre-1980s) Vintage Seiko many references Vintage Tudor and Heuer Military watches — plexi is more shock-resistant Step-by-Step Instructions Check the type of your crystal. If in doubt, test on a small, inconspicuous spot. Polywatch is not suitable for sapphire. An acrylic crystal can be identified by its slight optical distortion at the edges. Clean the crystal. Use a microfiber cloth to remove any dust, grease, or residue. A speck of dust can create new scratches during polishing. Protect the case. Use masking tape (like Washi tape) around the crystal to protect the case from accidental contact with the paste. Apply Polywatch. Dab a rice-grain sized amount directly onto the crystal. No need for more. Polish. With a soft cloth or a piece of cotton, rub in firm circular motions for 2 to 3 minutes. Apply sustained pressure and polish perpendicular to the direction of the scratches. Wipe. Remove all residues with a clean section of the cloth. Inspect the crystal under light. Repeat if necessary. Deep scratches may require 2 or 3 successive applications. Professional Tip: If you can feel the scratch with your fingernail, it's too deep for Polywatch alone. You will either need to entrust the watch to a watchmaker, or use a more abrasive method (fine sandpaper, 2000+ grit) before finishing with Polywatch. What Polywatch cannot do Remove deep scratches (more than 0.1 mm) Polish a sapphire crystal (this requires a machine and diamond discs) Polish a coated crystal (anti-reflective) — polishing would remove the coating Restore a cracked or split crystal — it must then be replaced Cape Cod: The Complete User Guide What exactly is Cape Cod? Cape Cod cloths are polishing compound-impregnated fabrics made in the United States. This compound combines chemical action (which slightly dissolves oxidation) and gentle mechanical action (micro-abrasion) to restore the shine of precious metals. Unlike Polywatch, Cape Cod does not remove material — it revives the existing surface. This is why it is ideal for regular use on polished steel cases and bracelets. Recommended Uses Stainless steel watch cases (polished finish only) Polished steel bracelets (Oyster, Jubilee, President) Buckles and clasps in steel or gold Gold watches (yellow, rose, white) — perfect for restoring shine Jewelry in silver, gold, platinum Step-by-Step Instructions Identify polished areas. Cape Cod is only to be used on mirror-polished surfaces, never on brushed or satin finishes — this would create permanent visible marks. Protect brushed surfaces. Use masking tape to cover brushed sections adjacent to the polished area you wish to treat. Remove a cloth from the pouch. Each pouch contains several cloths. Take one out — it should be slightly damp and fragrant (this is normal). Rub the surface. Apply the cloth to the polished area and rub in circular motions with moderate pressure. The cloth will gradually blacken — this is oxidation and micro-scratches being removed. Wipe with a clean cloth. Use a dry, clean microfiber cloth to remove Cape Cod residues and buff the surface to a shine. Store the cloth. Place the cloth back in its sealed pouch — a Cape Cod cloth is reusable 10 to 15 times. Important: Never soak your watch after using Cape Cod before thoroughly wiping off residues. The product could potentially seep into the gaskets if it remains in prolonged contact with the watch. What Cape Cod cannot do Remove deep scratches — this requires professional repolishing Be used on brushed or satin finishes Be used on PVD, DLC, gold-plated coatings — it would damage them Be used on watch crystals Recommended Usage Frequency Polywatch: only when needed, when a scratch hinders dial readability. Too frequent use will thin the crystal. Once or twice a year is sufficient for most watches. Cape Cod: every 2 to 3 months for regular maintenance. The product acts gently and can be used more frequently without risk, as long as the watch is thoroughly wiped afterward. Mistakes to Absolutely Avoid Using Cape Cod on glass — even mineral glass can be damaged by chemical components. Using Polywatch on sapphire — ineffective and risks leaving an opaque film. Mixing the two products on the same surface. Using Cape Cod on a brushed finish — you will create permanent visible marks. Polishing without cleaning the surface first — dust particles create new scratches. Neglecting to remove residues — especially for Cape Cod, as the product can alter gaskets. Polywatch and Cape Cod at MisterChrono Paris We offer Polywatch and Cape Cod in permanent stock at our Paris store (23 rue Danielle Casanova, 75001) as well as on our online site. Our advisors can also demonstrate the correct usage technique in-store — feel free to visit us with your watch if you have any doubts about the type of crystal or coating. For deep scratches or full case polishing, we always recommend entrusting the watch to a professional watchmaker.

Expert Guide · Published by David · MisterChrono Paris 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: Rolex Model Compatible References Available Series Submariner 114060, 116610, 126610 (ceramic & non-ceramic) Classic, Couture, Tang Buckle GMT-Master II 116710, 126710 (ceramic, Pepsi, Batman, Sprite) Classic VulChromatic, Couture Daytona 116500LN, 126500LN (ceramic) Classic, Couture Sea-Dweller 116600, 126600, Deepsea 116660 Classic, Tang Buckle Explorer 214270, 124270, Explorer II 216570 Classic, Tang Buckle Sky-Dweller 326934, 326935, 326938 Tang Buckle (with notch) Oyster Perpetual 124300 (41mm) Classic Milgauss 116400GV Rubber Cuff Series 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. Why choose RubberB at MisterChrono? MisterChrono is an official and selected reseller of RubberB straps.

Learn moreWhich Watch Bracelet for Your Rolex Submariner? The Complete 2026 Guide
Expert Guide · By Pierre-Yves · MisterChrono Paris Which watch strap for your Rolex Submariner? The complete 2026 guide The Rolex Submariner is much more than a dive watch. It is an absolute icon of modern watchmaking, worn on Parisian terraces as well as in La Défense meeting rooms. And like any icon, it deserves a strap befitting its status. In this 2026 guide, we help you choose the perfect strap for your Submariner — according to your style, your daily use, and the look you want to project. Why change your Submariner's original strap? The Rolex Submariner comes standard with the famous stainless steel Oyster bracelet — a timeless, robust, and instantly recognizable choice. Yet, more and more enthusiasts are choosing to personalize their watch with a quality aftermarket strap. The reasons are many: Personalization and uniqueness: in a country where Submariners are ubiquitous, a different strap allows you to express your personality without betraying the spirit of the watch. Daily comfort: some wearers find steel heavy on long days. Leather or rubber straps offer a lighter and often softer alternative on the wrist. Preserving value: keeping the original bracelet in its box and using an aftermarket strap daily is a smart strategy to maintain your Submariner's resale value. Outfit versatility: switching from a brown leather strap for a city dinner to a colorful NATO for the weekend means having several watches in one. At MisterChrono, we assist Parisian clients with this every week, from our store at 23 rue Danielle Casanova, Paris 1er. Our team knows every Submariner reference — from the vintage 5513 model to the new 126610 references — and will advise you on the strap that perfectly matches your use. The different types of straps compatible with the Rolex Submariner Before you start, it's essential to understand the available options. The Submariner case measures 40 mm (older models) or 41 mm (Submariner Date post-2020), with lugs suitable for a 20 or 21 mm wide strap. Here are the main families of straps we recommend at MisterChrono. 1. The NATO strap: casual elegance Born in the corridors of the British army in the 1970s, the NATO strap is today an essential reference in the world of sports and luxury watches. For the Submariner, it naturally stands out: its robust look, varied colors, and ease of fitting make it the ideal choice for the urban wearer. The most popular versions in Paris remain the classic grey and red (known as "Bond NATO", popularized in James Bond: Goldfinger) and the solid black, very elegant in a professional setting. Expect to pay between 15.90 and 49.90 euros for a seriously good quality NATO depending on the materials — flat woven nylon, satin, or even perlon. Pierre-Yves' tip: For a black Submariner (black bezel and dial), an anthracite grey nylon NATO provides remarkable chromatic coherence without overburdening the wrist. This is the combo I recommend to 9 out of 10 clients looking for a "casual chic" look in Paris. 2. The leather strap: Parisian sophistication We often hear it said: "a Submariner with leather, that's not done". Wrong — and we demonstrate it every day in our store on rue Casanova. A well-chosen leather strap radically transforms your Submariner, anchoring it more in the realm of a dress watch. It's the perfect compromise for those who wear their sport watch to the office. We particularly recommend: Smooth black or dark brown calfskin: absolute sobriety and versatility. Compatible with almost all city outfits. Embossed leather (crocodile or lizard): an extra touch of elegance, ideal for Parisian dinners or cultural outings. Perforated or sport leather: for those who want to keep the adventurous spirit of the Submariner while avoiding steel. Be careful, however: leather and water do not mix well. If you wear your Submariner to the pool or by the Seine, prefer rubber or NATO. 3. The rubber / FKM strap: the connoisseurs' choice Long reserved for professional divers, high-performance rubber straps — especially in FKM (fluoroelastomer) — have conquered the world of luxury watchmaking over the years 2010-2020. And for good reason: it combines exceptional resistance to water, UV, and perspiration, while offering unparalleled comfort. On a Submariner, the result is sporty and modern. Premium brands like Rubber B, or our exclusive MisterChrono selection, offer custom-molded rubber straps for Rolex cases — ensuring a perfect fit down to the millimeter. FKM is also the queen material for active wearers: running around the Bois de Boulogne, playing tennis at the Racing Club, sailing from Brest or La Rochelle — it resists everything without ever deteriorating. 4. The aftermarket metal bracelet: the alternative to the Oyster If you want to stay in the metal register without opting for the original Rolex bracelet (often difficult to find alone and expensive), quality aftermarket metal bracelets are an excellent option. The best references in brushed/polished 316L steel faithfully reproduce the Oyster aesthetic with some subtle variations — modified links, different clasp, exclusive satin finish. These bracelets are particularly appreciated by collectors who wish to vary looks without investing in a second copy. How to correctly measure and choose your strap size? Before any purchase, two measurements are essential: The lug width: for the Submariner, this is 20 or 21mm. All our MisterChrono bracelets referenced "Rolex Submariner" are designed for this width. The strap length: measure your wrist with a flexible tape measure. The majority of French male wrists are between 17 and 20 cm. Our leather straps are available in standard length (approximately 115 mm + 75 mm) and XL size for larger wrists. If you have any doubt, come and see us directly at 23 rue Danielle Casanova, Paris 1er: our team will be happy to measure your wrist and try several straps on your watch before purchase. We have professional installation tools and spring bar guides adapted to each Submariner model. Our 2026 selection: favorite straps for the Rolex Submariner ⭐ Best all-rounder — Premium Nylon NATO 20mm The absolute classic. High-density woven nylon, brushed steel buckle, available in 12 colors.

From 79 € — View the Rubber collection on MisterChrono Frequently asked questions about the Rolex Submariner strap Can I change the strap of a Rolex Submariner without damaging the watch? Yes, absolutely — provided you use the right tools. A good quality spring bar tool and careful handling are enough to remove the bars between the lugs. We offer this service free of charge in-store for any strap purchase at MisterChrono. If you want to do it yourself, we recommend our tutorial available on the website. Does changing the strap affect the resale value of my Rolex? No, if you carefully keep the original bracelet with all its adjustment links. A Submariner presented complete (case + bracelet + papers) retains its full value on the secondary market. This is also the strategy adopted by the majority of our Parisian collector clients. What strap width for a Rolex Submariner? The Rolex Submariner uses lugs designed for a 20 mm wide strap for 40mm models or 21 mm for 41mm models. All our MisterChrono straps referenced for the Submariner respect this standard dimension. Is the NATO strap suitable for professional use? In the 2020s, the NATO has largely outgrown its "outdoor" image to integrate into business casual codes. In France, it is now common to see Parisian executives and managers wearing a Submariner on a NATO in professional settings. Choose a neutral color (grey, navy, black) and a superior nylon quality for an impeccable result.
