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

  1. 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.
  2. Clean the crystal. Use a microfibre cloth to remove dust, oils and residue. A single dust particle can create new scratches during polishing.
  3. 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.
  4. Apply Polywatch. Squeeze a rice-grain-sized amount directly onto the crystal. No need for more.
  5. 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.
  6. Wipe clean. Remove all residue with a clean section of the cloth. Inspect the crystal under good lighting.
  7. 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

  1. 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.
  2. Protect brushed surfaces. Use masking tape to cover brushed sections adjacent to the polished area you want to treat.
  3. Take a cloth from the pack. Each pack contains multiple cloths. Remove one — it should be slightly damp and scented (this is normal).
  4. 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.
  5. Wipe with a clean cloth. Use a clean, dry microfibre cloth to remove Cape Cod residue and bring out the shine.
  6. 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.

Watch Strap Gift Guide for Father's Day 2026 – All Budgets | MisterChrono Singapore

Father's Day Gift Guide · Singapore 2026 Watch Straps: The Ultimate Father's Day Gift Guide for 2026 — Every Budget, Every Dad By Pierre-Yves · MisterChrono Singapore, Mandarin Gallery, Orchard Road Father's Day in Singapore falls on Sunday, 15 June 2026 — and if you're still searching for a gift that is genuinely thoughtful, beautifully personal and built to last in our humid tropical climate, a premium watch strap might just be the smartest choice you'll make this year. Think about it: Dad already has his watch. Whether it's a well-worn Rolex Submariner, a trusty Seiko that's been on his wrist for a decade, or a sentimental Omega passed down from his own father — what he probably doesn't have is a strap that reflects who he is today. A new strap transforms a familiar timepiece into something that feels brand new. It's the kind of gift that shows you know him, not just what he's wearing. At MisterChrono Singapore, available in-store at Mandarin Gallery, 333A Orchard Road, we carry an expertly curated range of watch straps sourced from the world's finest manufacturers. And because we know Singapore families come in all shapes — and budgets — this guide covers everything from accessible everyday upgrades to heritage luxury pieces that will make him genuinely speechless. Let's find the perfect strap for your dad. Why a Watch Strap Makes the Perfect Father's Day Gift in Singapore Gift-giving in Singapore often carries an unspoken pressure: it should feel luxurious but not wasteful, meaningful but not overly sentimental. A premium watch strap hits that sweet spot effortlessly. Unlike a bottle of whisky or a restaurant voucher, a fine strap is something Dad will interact with every single day. Every morning he fastens it. Every meeting, every weekend kopi session at the hawker centre, every family gathering — it's there. The gift keeps giving in the most understated, elegant way possible. There's also a deeply practical consideration that is unique to living in Singapore: our equatorial climate is relentless. The heat, the humidity, the sudden afternoon downpours — they take a toll on watch straps, particularly leather. Many Singapore watch enthusiasts actually maintain a rotation of straps: a rubber or tropical-style strap for daily wear and weekends outdoors, and a finer leather or textile strap for the office or formal occasions. Gifting a strap that is suited to Singapore's conditions is not just thoughtful — it's genuinely useful. And finally: the price range is extraordinary. You can spend SGD 80 or SGD 800 and both can be exceptional gifts. Let us guide you through both ends of the spectrum and everything in between. The Singapore Dad Archetypes — Which One Is Your Father? Before diving into products, it helps to think about who your dad actually is. We've identified four profiles we see regularly at our Mandarin Gallery boutique: 🏊 The Active Weekend Dad He runs at East Coast Park before sunrise, coaches his kid's football team on Saturday mornings, and still swims at the condo pool after work. His watch goes everywhere with him and needs a strap that can handle it. Rubber straps and FKM fluoroelastomer straps are his best friends — sweat-resistant, water-resistant, and easy to clean. 👔 The CBD Professional He works in finance, law, or consulting along Raffles Place or Marina Bay. His watch is a statement in the boardroom. He wants something that reads quality instantly — a fine leather strap in black or dark brown, or an elegant alligator-embossed option that quietly signals refinement without being loud about it. 🌿 The Lifestyle Collector He has more than one watch. He reads Hodinkee during his lunch break. He appreciates provenance, craftsmanship, and the story behind the materials. For him, a heritage leather strap from a storied French or Italian manufacture, or a hand-stitched rally strap, is the kind of find that will genuinely excite him. 👴 The Sentimental Dad His watch has been on his wrist since his wedding day, or it was a gift from his own late father. It might be worn, the original bracelet scratched and slightly stretched. He'd never replace the watch — but a beautiful new strap is a way to honour it. Go for something classic: a simple, well-made leather strap in a neutral tone, understated and timeless. Our Gift Picks by Budget — All Available at MisterChrono Singapore Under SGD 120 — The Smart Starter This budget is more capable than you might think. At this level, you can access genuine NATO straps in nylon or G10 canvas, quality rubber sport straps, and entry-level leather straps that are stitched cleanly and built to last. These are excellent for the dad who wants a casual, quick-change strap for weekend outings or sporty use. A NATO strap in a Singapore-inspired colourway — think navy and red, or olive and tan — gives his tool watch an entirely new personality without altering the watch itself. It's also a fantastic conversation starter. NATO straps were originally designed for military use, and the history alone makes the gift more interesting when you tell him about it. Best for: The Active Weekend Dad, younger dads, or a first strap rotation purchase. SGD 120–280 — The Considered Gift This is the sweet spot for many Singapore families — a price point that feels genuinely generous without being reckless. In this range, you access premium rubber straps in FKM fluoroelastomer — the material used by brands like Rolex and Tudor on their own sport references — as well as genuine calf leather straps with high-quality linings and hand-bevelled edges. For Singapore's climate, we particularly recommend a tropical-style or perforated rubber strap at this budget. The perforations allow airflow directly against the wrist — a feature that makes a meaningful difference when you're outdoors at a garden wedding, a Sentosa beach club lunch, or just navigating the heat between MRT stations. Alternatively, a sharp deployant clasp leather strap in this range elevates the presentation considerably. The deployant clasp alone adds a luxury feel that mirrors what you'd find on a factory bracelet — it's a detail that watch enthusiasts notice and appreciate. Best for: The CBD Professional, the Lifestyle Collector, or as a gift from adult siblings pooling together. SGD 280–600 — The Connoisseur's Choice At this level, we enter the territory of genuine horological luxury. Straps crafted from hand-selected alligator or crocodile leather, sourced from French manufactures with generations of expertise, stitched with waxed linen thread and finished with hand-painted edges. This is the kind of strap that watch collectors talk about. A Louisiana alligator strap with matte finish in midnight blue or chocolate brown is breathtaking in person — the scale pattern catches the light in a way that photographs cannot fully capture. Paired with a deployant clasp in brushed steel or rose gold, it is a complete transformation of any dress or sports-luxury watch. In Singapore's social landscape, where gift-giving carries cultural weight — especially between adult children and their parents — this range communicates genuine respect and appreciation in a way that is elegant rather than ostentatious. It's luxury with discretion, which is deeply aligned with Singapore's culture of understated success. Best for: The Lifestyle Collector, the Sentimental Dad whose watch deserves an exceptional strap, or as a landmark gift for a milestone birthday doubling as Father's Day. SGD 600 and Above — The Heirloom Gift This is rare territory, and it is remarkable. Above SGD 600, you are selecting from straps that are essentially small works of art: exotic skins — genuine ostrich, hornback crocodile, or hand-painted custom leathers — crafted by artisans whose workshops have supplied the great Swiss and French Maisons for decades. Some pieces in this range are hand-numbered or bespoke. For a Singapore father who has spent his life building something — a family, a career, a collection — this is a gift that carries that same weight. It's not purchased impulsively; it's chosen with care, and he will know that immediately. We recommend visiting our Mandarin Gallery boutique in person for this tier, where our team can guide you through the textures, colours and combinations. There is no substitute for handling these straps before you decide. Matching the Strap to His Watch — A Quick Reference Guide Not sure which strap will work with his specific watch? Here are some of the most common references we help Singapore customers with at the boutique: Watch Reference Lug Width Recommended Strap Style Rolex Submariner / Sea-Dweller 20mm FKM rubber, NATO nylon Omega Seamaster 300M 20mm Rubber sport, perforated tropical IWC Portugieser / Pilot 20–22mm Alligator leather, deployant clasp Tudor Black Bay 22mm Leather heritage, NATO canvas AP Royal Oak Offshore 26–28mm Rubber integrated, exotic skin Seiko SKX / Prospex 20–22mm Rubber, perforated, NATO Patek Philippe Calatrava 18–20mm Alligator, pin buckle, classic finish Not sure of the lug width? Bring the watch into our Mandarin Gallery boutique and our team will measure it on the spot — no appointment needed. Singapore-Specific Tip: Think About the Climate First This is a point we genuinely cannot stress enough. Singapore sits at 1.3° North of the equator. Our average humidity runs at 84% relative humidity. Our average daily high is around 31–33°C year-round, with no real dry season to speak of. These are not conditions that traditional European leather straps were designed for. This doesn't mean you can't give Dad a leather strap — of course you can, and many Singapore professionals wear fine leather straps beautifully in air-conditioned office environments. But if his lifestyle involves significant outdoor time, consider a rubber or FKM fluoroelastomer strap as the primary gift, paired perhaps with a leather option as a secondary piece for formal occasions. Rubber straps have also evolved enormously in quality and aesthetic. The days of industrial-looking rubber bands are long gone. Today's premium rubber straps feature hand-finished surfaces, subtly embossed textures, bevelled edges and colour gradients that are genuinely beautiful objects. They happen to also be completely impervious to sweat, rain and poolside splashes — which, in Singapore, is a major advantage. At MisterChrono Singapore, we have an excellent selection of climate-appropriate straps — come in and let us show you what has changed in the category over the past few years. You might be surprised. How to Give the Gift Beautifully — Presentation Matters A premium watch strap deserves a presentation that matches its quality. At MisterChrono Singapore, every strap purchase comes beautifully packaged — but here are a few additional ideas to make Father's Day morning memorable: Change the strap before gifting it — if you have access to his watch, ask our team at Mandarin Gallery to fit the new strap. He unwraps his own watch, wearing its new strap, already on the pillow. That moment is unforgettable. Include a handwritten note explaining why you chose that specific strap — the craftsmanship, the colour, what it reminded you of. Singapore fathers are often less sentimental in expression but deeply appreciate being seen. Pair it with a strap-changing tool — available at the boutique, these small spring bar tools make changing straps simple and damage-free. It's a practical addition that encourages him to actually use the strap. Gift a second strap — one rubber for weekends, one leather for the office. Two straps at the SGD 80–120 range can create a more impactful package than one strap at a higher price point. Visit Us at Mandarin Gallery — Or Shop Online Our Singapore boutique is located at Mandarin Gallery, 333A Orchard Road, #02-19, Singapore 238897. We are open seven days a week, and our team is fluent in English, Mandarin and Bahasa — no appointment necessary for strap consultations. If you prefer to browse first, our full collection is available online. You can filter by lug width, material, watch brand compatibility and price — and all SGD prices include local GST with no hidden charges. We offer complimentary local delivery on orders above SGD 80, and same-day dispatch for orders placed before 12PM on weekdays — meaning if you're organised, you can have the gift in your hands well before 15 June 2026. Father's Day is not about the price tag. It's about showing your father that you see who he is — and a strap you've chosen with intention does exactly that, every single day he wears it.

KronoKeeper Squama Watch Straps: Salmon Leather, A French Material of Exception

New collection · Written by Pierre-Yves · MisterChrono Singapore KronoKeeper Squama Watch Straps: Salmon Leather, A French Material of Exception A new KronoKeeper collection crafted from authentic salmon leather, vegetable-tanned in France. Twelve colours across two exclusive finishes: Satin and Gradient. At MisterChrono Singapore, we are proud to introduce a new collection that is particularly close to our hearts: the KronoKeeper Squama collection. Crafted from authentic salmon leather, these watch straps embody artisanal excellence, eco-responsibility and contemporary elegance. This article walks you through the material, the French craftsmanship behind it, the two collection finishes, and all twelve colours now available in our boutique and online. Salmon leather: an exceptional marine material Salmon leather remains an underground material in the watch world, yet it possesses every quality of an exceptional leather: a unique natural scale grain, surprising suppleness, and remarkable resistance to wear. Its distinguishing feature is its origin: every hide is sourced from food industry by-products in France. No animal is farmed for its skin — this is a material fully upcycled from existing supply chains, in a genuinely circular and responsible approach. The result: a leather with fine, regular scales reminiscent of traditional exotic skins (python, alligator) while offering an ethical, local and sustainable alternative. French artisanal craftsmanship Our Squama leather comes from a partner French tannery, based in the Lyon region, specialised in marine leathers. The vegetable tanning process, carried out in France, follows the traditions of fine leather goods: long duration, artisanal know-how, control of every step. This process gives salmon leather its unique properties: Exceptional suppleness — the strap conforms to the wrist quickly Water resistance superior to most terrestrial leathers — especially valuable in Singapore's humid tropical climate Natural scale grain — each piece is unique, no two hides are identical Longevity — salmon leather develops a subtle patina over the years In collaboration with this French tannery, KronoKeeper developed the Squama collection: twelve colours across two finishes, designed specifically for watch straps. Satin finish: eight pure and mineral colours The Satin finish is the matte signature of the collection. The leather is dyed through the core, then lightly satined to reveal the natural structure of the scales without excessive shine. The result is understated, elegant, perfectly suited to both dress and sport-chic watches. Origine Natural undyed, matte finish Carbone Deep contemporary black Spiruline Elegant marine algae green Lie de vin Refined deep bordeaux Bleu Baltique Deep marine blue Verglacé Light mineral grey Moka Warm chocolate brown Nuage Subtle pearl grey Each Satin strap is lined with calf leather and hand-stitched with matching thread, in the pure tradition of luxury straps. Gradient finish: four colours with metallic highlights The Gradient finish represents Squama's contemporary signature. On each scale, two shades blend through an exclusive dyeing process, creating a subtle gradient that catches light differently depending on the angle. The effect is striking — a strap that changes appearance with the movement of the wrist. Odyssée Bright metallic coppery red Encre d'Or Lavish black and gold Bleu Minuit Midnight blue with copper highlights Rouge Impérial Intense deep red These Gradient straps are particularly stunning on watches with understated dials, adding a touch of contemporary boldness. Technical specifications Specification Detail Material Authentic salmon leather, vegetable-tanned in France Lining Smooth calf leather Stitching Hand-stitched, matching thread Available sizes 18-16mm, 19-18mm, 20-18mm, 21-16mm, 22-20mm Available lengths 105/65 mm (standard) or 115/75 mm (long) Leather origin Vegetable-tanned in France · Designed by KronoKeeper Caring for your salmon leather strap Squama leather is resilient and easy to live with, but a few simple practices extend its lifespan — particularly important in Singapore's humid tropical climate: Avoid prolonged contact with seawater or chlorinated pools Condition the leather once or twice a year with a fine leather cream Store away from direct sunlight during long periods of non-wear For light cleaning, use a slightly damp microfibre cloth Which watch pairs well with a Squama strap? The Squama collection lends itself remarkably well to dress watches in steel or gold, but also to sport-chic timepieces. Some pairings we particularly recommend: Rolex Datejust — a Satin Origine or Carbone elevates the jewellery character of the watch Omega Aqua Terra — a Satin Bleu Baltique resonates perfectly with blue dials Tudor Black Bay — a Gradient Bleu Minuit adds refined contrast Patek Philippe Calatrava — a Satin Lie de vin dresses up the classic with daring JLC Reverso — a Gradient Encre d'Or for a spectacular jewel-like effect The Squama collection at MisterChrono Singapore The KronoKeeper Squama collection is available at our Singapore boutique (Mandarin Gallery #03-04, 333A Orchard Road) and on our online store. Our expert advisors can present the colours in natural light, help you choose the shade that will elevate your watch, and fit the strap on site. Salmon leather is especially well suited to Singapore's climate — its natural water resistance and supple grain handle humidity better than many traditional leathers.

Kronokeeper FKM Alligator Watch Strap - Black Rubber Embossed

Kronokeeper unveils an exceptional piece that redefines the watch strap category: the FKM Alligator Black. For the first time, the refined aesthetics of alligator leather meet the extreme durability of FKM rubber — a technical and aesthetic achievement crafted for watch enthusiasts who refuse to compromise between elegance, toughness, and versatility. The elegance of exotic leather, the resilience of high-performance rubber At first glance, the illusion is flawless. The alligator grain is embossed with remarkable precision, instantly evoking the finest exotic leather straps from Place Vendôme ateliers. Every scale is sharply defined, every shadow of the relief carefully shaped to capture the natural depth of genuine hide. Yet this strap is not leather at all: it is entirely crafted from FKM rubber, a technical material used in aerospace and professional diving. This unique fusion delivers a completely new wearing experience: you wear a strap that looks luxurious, yet you can dive into the ocean, expose it to tropical sun, sweat through a workout, or wear it through pouring rain — with zero degradation. What is FKM rubber? FKM (fluoroelastomer) is a high-end rubber originally developed for demanding industrial and military applications: aircraft engine seals, technical diving equipment, chemical industry. It belongs to the same family as Viton®, the global benchmark for fluoroelastomers. Unlike conventional synthetic rubbers, FKM is impervious to: Saltwater and pool chlorine UV rays and tropical climates Oils, solvents, and chemicals Sweat and cosmetics (sunscreen, perfume) Extreme temperatures, from -20°C to +200°C (-4°F to 392°F) It is also a hypoallergenic, completely odorless material that retains its suppleness and shape year after year. A quality FKM strap can last a decade without losing its original appearance. Technical specifications Main material: FKM rubber (high-performance fluoroelastomer) Inner surface: soft rubber lining, micro-textured for optimal wearing comfort, even during heavy perspiration Outer finish: genuine alligator-style embossing, sharp and realistic relief Color: deep black, matte finish with a subtle satin touch Resistance: saltwater, chlorine, UV, sweat, oils, solvents Temperature range: -20°C to +200°C (-4°F to 392°F) Properties: hypoallergenic, odorless, does not yellow, retains suppleness over time Attachment system: standard spring bars, compatible with any pin buckle or deployant clasp Manufacturing: Swiss watchmaking standards Which watches and which uses? The Kronokeeper FKM Alligator strap is designed to suit a wide range of character watches, whether sporty or dressy. Its refined aesthetics make it an ideal companion for: Dive watches: Rolex Submariner, Rolex Sea-Dweller, Omega Seamaster Diver 300M, Tudor Black Bay, Blancpain Fifty Fathoms, Panerai Submersible Sports chronographs: Rolex Daytona, Omega Speedmaster, Breitling Navitimer, TAG Heuer Carrera, Zenith El Primero Dress-sport watches: Rolex Datejust, Omega Aqua Terra, IWC Portugieser, Jaeger-LeCoultre Polaris, Panerai Luminor Due Tool watches: Tudor Pelagos, Omega Planet Ocean, Rolex Explorer The ultimate versatile strap, it adapts to every occasion: office meetings, dinners in town, weekends by the sea, tropical vacations, sports sessions. One strap, every occasion. Why choose an FKM strap over a genuine alligator leather strap? A genuine alligator leather strap is a magnificent piece, but a fragile one. It fears water, does not tolerate prolonged perspiration, degrades under UV exposure, and quickly loses its luster in humid climates. For climates like Hong Kong, Singapore, or southern France in summer, an exotic leather strap demands regular maintenance and constant protection. The Kronokeeper FKM Alligator strap offers the same visual impact — unless you look very closely — with complete freedom of use. It's the rational choice for collectors who actively live with their watches. Care and durability Caring for the FKM Alligator strap is disarmingly simple. A quick rinse with clean water is enough after ocean or pool exposure. For deeper cleaning, use lukewarm soapy water with a soft cloth. No need for wax, oil, or special products. Unlike leather, FKM does not dry out, crack, or require preventive protection. Kronokeeper craftsmanship Kronokeeper is a premium watch strap atelier, an official partner of MisterChrono for several years. Every strap is crafted to Swiss watchmaking standards, with rigorous quality control at every stage: selection of virgin FKM rubber, precision molding, manual embossing, finishing, and final assembly. Kronokeeper also offers made-to-measure leather straps through our Bespoke by MisterChrono program, available in our boutiques in Paris, Singapore, Hong Kong, Manila, and Brussels. Shipping and warranty Fast shipping in secure packaging from one of our MisterChrono boutiques. Every Kronokeeper strap comes with a manufacturer warranty and after-sales service handled directly by our teams. For any question about sizing, compatibility with your watch, or buckle choice, our in-store and online advisors are at your disposal. Kronokeeper FKM Alligator Black — the elegance of exotic leather, the endurance of cutting-edge rubber. The strap that doesn't compromise.
