The Omega × Swatch MoonSwatch ships on a Velcro strap, and while that's part of the watch's playful identity, it also means a lot of owners are looking for alternatives almost immediately. This collection gathers 20 mm replacement bands that work with the MoonSwatch's case geometry — a combination of Swatch's standard 20 mm lug width and the bioceramic case's slightly rounded lug shoulders.

**Sizing and compatibility** The MoonSwatch uses standard 20 mm straight lugs, which means any quality 20 mm strap is technically compatible. However, the short lug-to-lug distance on the case means very thick or heavily tapered straps can look awkward. Flat or lightly tapered straps — rubber, leather, nylon — sit cleanest. If you're unsure, our [watch band size guide](/pages/watch-band-size-guide) includes the MoonSwatch case profile with recommended taper ranges.

**right strap options by use-case** For casual daily wear, a two-piece rubber strap in a matching Mission colorway preserves the original look with more comfort and structure than the stock Velcro. For a dressier configuration, a slim flat leather strap (especially in beige or sand tones for Moonshine Gold editions) transitions the watch to evening wear. NATO and nylon weaves add durability for active or travel use — see our full [NATO strap selection](/collections/design-natos). Original-style Velcro replacement bands are also available here if you want to match the stock look with fresh hardware.

**A note on the stock strap** Swatch's Velcro band is 20 mm wide but uses a proprietary curved spring bar that differs slightly from standard straight-bar setups. Most 20 mm aftermarket bands with standard spring bars fit without modification.
