UK brand & UK support
Built around 20mm wearers
20mm done properly, not as a one-size afterthought.
Our 20mm straps are profiled and colour-matched, not stamped out of a generic mould — so they sit clean on slim cases like MoonSwatch as well as chunkier 20mm sports watches.
True 20mm spring-bar fit
Built to standard 20mm lug width with quality spring-bar tolerance, so it drops in and stays put on any 20mm-lug watch.
Soft-touch premium silicone
Comfortable on long wears, sweat- and water-resistant, with a tactile finish that works on both casual and sports cases.
Honest, UK-trusted claims
Sold as compatible replacement straps — never branded as official product from any watch maker. Supported by a UK team.

20mm strap FAQs
Everything UK 20mm buyers ask before ordering.
- How do I know if my watch is 20mm?
- Measure the gap between the lugs (where the strap meets the case) in millimetres. Common 20mm watches include the Omega × Swatch MoonSwatch, the AP × Swatch, many Swatch New Gent style cases, and most modern sport / dress watches.
- Will a 20mm StrapWatch strap fit my MoonSwatch or AP × Swatch?
- Yes — both the MoonSwatch and AP × Swatch use a 20mm spring-bar fit, so our 20mm straps drop in cleanly on either.
- How do I change a 20mm watch strap?
- Use a basic spring-bar tool to compress the spring bar, lift the strap, and drop the new one in. The whole swap takes under two minutes.
- Are these official watch brand straps?
- No. StrapWatch is an independent UK brand making compatible 20mm replacement straps. We are not affiliated with Omega, Swatch Group, Audemars Piguet or any other watchmaker.
- How fast is UK delivery?
- Orders are picked, packed and dispatched tracked from the UK, with delivery options and pricing shown securely at checkout.
