Polywatch and Cape Cod: Complete Guide for Watch Care | MisterChrono Singapore
Expert guide · Written by Pierre-Yves · MisterChrono Singapore Polywatch and Cape Cod: The Complete Guide to Polishing Watch Crystals and Cases Two essential products, two distinct uses. How to use Polywatch for crystal scratches and Cape Cod to restore your watch case — step-by-step instructions for professional results at home. Every watch collects the marks of time: a fine scratch on the crystal, a case that has lost its original gleam, a steel bracelet dulled by daily micro-scratches. The good news: most of these imperfections can be corrected at home, in a few minutes, using two professional products we have recommended to our clients at MisterChrono Singapore for years — Polywatch and Cape Cod polishing cloths. This complete guide explains what each product does, which uses it is designed for, and most importantly how to use it correctly to achieve professional results without risking damage to your watch. Polywatch vs Cape Cod: what is the difference? First, understand this: these are two complementary products, not interchangeable. Using one instead of the other can damage your watch. Criterion Polywatch Cape Cod Form Paste in a tube Pre-treated cloths Primary use Scratches on acrylic (plexi) crystals Micro-scratches on metal (steel, gold) Mode of action Fine abrasion (micro-particles) Chemical action + gentle abrasion Compatible surfaces Acrylic / plexiglass only (standard version) Stainless steel, gold, silver, brass Incompatible surfaces Sapphire, mineral glass, coated surfaces Any crystal, PVD, DLC, brushed finishes Golden rule: Polywatch for acrylic crystals, Cape Cod for metal. Never swap them — Polywatch is too fine for metal and Cape Cod contains chemical compounds that can damage crystal seals and watch gaskets. Polywatch: complete how-to guide What is Polywatch exactly? Polywatch is a polishing paste manufactured in Germany, specifically formulated for acrylic watch crystals (Plexiglas / Hesalite). It contains fine abrasive micro-particles that remove a thin layer of plastic to smooth out scratches and restore crystal clarity. Polywatch comes in two main versions: Polywatch Plastic (red tube): for acrylic crystals (Plexiglas, Hesalite). The most common version. Polywatch Glass (blue kit): for mineral glass crystals. Note: not suitable for sapphire crystals. Watches that benefit from Polywatch Many iconic watches use an acrylic crystal that scratches easily but polishes just as easily with Polywatch: Omega Speedmaster Professional "Moonwatch" (original Hesalite crystal) Vintage Rolex (most references prior to the 1980s) Vintage Seiko (many references) Vintage Tudor and Heuer (sports chronographs) Military watches — acrylic resists shocks better than glass Step-by-step instructions Identify your crystal type. If in doubt, test on a small inconspicuous area. Polywatch does not work on sapphire. Acrylic crystals can be identified by their slight optical distortion at the edges. Clean the crystal. Use a microfibre cloth to remove dust, oils and residue. A single dust particle can create new scratches during polishing. Protect the case. Use masking tape (painter's tape or Washi tape) around the crystal to protect the case from accidental contact with the paste. Apply Polywatch. Squeeze a rice-grain-sized amount directly onto the crystal. No need for more. Polish. Using a soft cloth or cotton wool, rub the paste in firm circular motions for 2 to 3 minutes. Apply firm, consistent pressure and polish perpendicular to the direction of the scratches. Wipe clean. Remove all residue with a clean section of the cloth. Inspect the crystal under good lighting. Repeat if needed. Deep scratches may require 2 to 3 successive applications. Pro tip: if you can feel the scratch when running your fingernail over it, it is too deep for Polywatch alone. You will need to either take the watch to a professional watchmaker, or use a more abrasive method (fine 2000+ grit sandpaper) before finishing with Polywatch. What Polywatch cannot do Remove deep scratches (more than 0.1 mm) Polish sapphire crystals (requires diamond-disc machinery) Polish coated crystals (anti-reflective coating) — polishing would strip the coating Restore cracked or chipped crystals — those require replacement Cape Cod: complete how-to guide What is Cape Cod exactly? Cape Cod polishing cloths are fabric cloths pre-impregnated with a polishing compound, manufactured in the United States. The compound combines a chemical action (which dissolves light oxidation) and a gentle mechanical action (micro-abrasion) to restore the brilliance of precious metals. Unlike Polywatch, Cape Cod does not remove material — it revives the existing surface. This makes it ideal for regular maintenance of 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 reviving the shine Fine jewellery in silver, gold, platinum Step-by-step instructions Identify the polished areas. Cape Cod is used only 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 want to treat. Take a cloth from the pack. Each pack contains multiple cloths. Remove one — it should be slightly damp and scented (this is normal). Polish the surface. Apply the cloth to the polished area and rub in circular motions with moderate pressure. The cloth will gradually darken — this is oxidation and micro-scratches being lifted away. Wipe with a clean cloth. Use a clean, dry microfibre cloth to remove Cape Cod residue and bring out the shine. Store the cloth. Return the cloth to its sealed pack — a Cape Cod cloth is reusable 10 to 15 times. Important: never rinse or submerge your watch after using Cape Cod without first wiping all residue away thoroughly. The product can potentially infiltrate water-resistance gaskets if left in prolonged contact with the watch. What Cape Cod cannot do Remove deep scratches — a professional re-polish is needed Be used on brushed or satin finishes Be used on PVD, DLC or gold-plated coatings — it would damage them Be used on watch crystals of any kind Recommended frequency of use Polywatch: only as needed, when a scratch interferes with reading the dial. Using it too frequently will eventually 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, provided the watch is well wiped afterwards. In Singapore's humid tropical climate, regular Cape Cod maintenance is particularly beneficial — humidity accelerates oxidation on steel cases and bracelets, making more frequent care a practical choice. Mistakes to avoid at all costs Using Cape Cod on a crystal — even mineral glass can be damaged by the chemical components. Using Polywatch on sapphire — ineffective and may leave a cloudy 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 first — dust particles create new scratches. Neglecting to remove residue — especially for Cape Cod, as residue can damage gaskets.

Expert guide · Written by David · MisterChrono Singapore RubberB Straps for Rolex: The Complete Guide to Swiss Vulcanized Rubber Material, Blocked Integration technology, VulChromatic, series overview and full Rolex compatibility — everything you need to know before choosing your RubberB strap. When Rolex collectors decide to replace their Oyster bracelet, the choice of rubber strap matters enormously. Not all rubber straps are created equal — and RubberB, the Swiss manufacturer that pioneered custom rubber straps engineered exclusively for Rolex, has set the benchmark that every competitor is measured against. At MisterChrono Singapore, we carry the full RubberB range for Rolex. This guide breaks down everything: the material science behind RubberB straps, the proprietary technologies that make them unique, the four series available, and detailed compatibility across all major Rolex references. What makes RubberB different: 100% pure vulcanized rubber The most important thing to understand about RubberB straps is the material itself. Every single strap is manufactured from 100% pure vulcanized rubber — with absolutely no surface coating, no synthetic blends, no glue and no bonding agents of any kind. This matters because most competitors use silicone (cheaper, less durable) or rubber composites covered with a surface coating that eventually chips, cracks or discolours. RubberB works the material through the core: what you see is what the strap is made of, all the way through. Why vulcanized rubber outperforms silicone Colour stability: RubberB straps do not fade, even after prolonged saltwater exposure or tropical sun — critical for wearers in humid climates. Dust resistance: Pure vulcanized rubber does not attract dust or lint. The strap stays clean looking. Shape retention: The strap does not stretch, deform or develop a permanent set from daily wear. Hypoallergenic: Non-toxic, non-marking, non-allergen — exceeds FDA and BVGG certification requirements. Swiss manufacturing: Every strap is hand-finished in Switzerland to the exacting standards of the luxury watchmaking industry. Blocked Integration: the technology that changed rubber straps Blocked Integration is RubberB's core engineering innovation — and the reason why their straps look so different from generic rubber alternatives on a Rolex case. The technology works by embedding precisely micro-calibrated solid inserts into the strap's end pieces. These inserts are shaped to match the exact geometry of a specific Rolex case's lug holes, so when the strap is installed, it sits flush against the case — no gap, no wiggle, no movement. The visual result is striking: from the side profile, the strap appears to be part of the watch case itself, integrated like a factory configuration. Collectors often describe it as how a rubber strap "should have looked from Rolex." Important: Because Blocked Integration requires micro-calibration to each specific Rolex reference, there is no single "universal RubberB strap for Rolex." Each strap is engineered for a specific model — and in some cases, a specific generation of that model (e.g., Submariner pre-2010, 2010–2019, 2020–present). Our team at MisterChrono Singapore will identify the exact right version for your watch. VulChromatic: dual-colour rubber fusion VulChromatic is RubberB's patented dual-colour technology. It fuses two distinct shades of vulcanized rubber within a single strap with no visible joint, no stitching between colours and no bonding — the two colours are chemically united during the vulcanization process itself. This technology was developed specifically for the Rolex GMT-Master II family, where the bezel insert sports two contrasting colours. VulChromatic straps mirror this dual-tone identity on the wrist: GMT "Batman" (black/blue bezel): Black and blue VulChromatic strap GMT "Pepsi" (red/blue bezel): Red and blue VulChromatic strap GMT "Sprite" (green/black bezel): Green and black VulChromatic strap Explorer II (orange hand): Black with orange VulChromatic accent stripe All RubberB straps feature the brand's signature "T" design — a subtle identification mark that watch-knowledgeable eyes will recognize, without shouting branding at everyone else. The four RubberB series at MisterChrono Classic Series — the benchmark The original RubberB series and still the most popular. The Classic Series accommodates all wrist sizes from XXS to XL (14 to 21 cm / 5.5 to 8.25 inches) and mounts directly to your existing Rolex Oyster deployant clasp — no additional links or tools required beyond a standard spring bar tool. Available in a wide range of solid colours and VulChromatic dual-colour combinations. Couture Series — elevated refinement The Couture Series elevates the Classic with one critical detail: Gore Tenara stitching running along the strap's edges. Gore Tenara is the same thread used in high-performance outdoor gear — rot-proof, UV-stable and maintenance-free for life. The stitching transforms the strap into something closer to fine leather goods, adding a tailored luxury dimension to the rubber sport aesthetic. Tang Buckle Series — independent buckle system Designed for collectors who prefer not to use their Rolex Oyster clasp as the fastening mechanism — or who own multiple watches and want a strap that works independently. The Tang Buckle Series features a 316L stainless steel tang buckle (the same surgical-grade steel Rolex uses for case construction), offering a clean, traditional strap look with a different wrist feel than the deployant system. Rubber Cuff Series — unique texture, same performance The Rubber Cuff is RubberB's most distinctive creation. It looks and feels like a fine woven textile — the texture mimics soft twill or perforated fabric — but it is 100% rubber, therefore waterproof and maintenance-free. Available in black, blue and green, the Rubber Cuff is most frequently paired with the Rolex Milgauss, where it complements the watch's unconventional character. Full Rolex compatibility guide RubberB produces a dedicated, micro-calibrated strap for each Rolex reference.

Installation requires a standard spring bar tool and takes approximately 5 minutes. The process: Remove your existing bracelet's spring bars from the Rolex case lugs. Insert the RubberB strap end pieces into the case lugs — the Blocked Integration inserts guide the strap into the correct position. Reinstall the spring bars to secure the strap. Attach your Rolex Oyster clasp to the strap's end loop. Complimentary strap fitting: For any RubberB strap purchased at MisterChrono Singapore, our team will install the strap on your watch at no charge. We also verify the correct reference compatibility before fitting. Caring for your RubberB strap After saltwater or pool exposure: Rinse with fresh water and dry with a microfibre cloth. Routine cleaning: A slightly damp cloth with mild soap. Any residue wipes away easily — vulcanized rubber does not absorb stains. Sunscreen contact: Avoid prolonged contact. Rinse after beach use. Storage: Keep away from extreme heat and direct UV light for long-term storage. For daily rotation, no special precautions needed.
