21mm Watch Straps

Finding a well-made 21mm watch strap can take a little more searching than other lug widths. We've brought together leather, textile and military G10-style straps from trusted makers including Hirsch, Fluco and Erika's Originals, giving you quality options designed specifically for this less common size. If you're unsure whether your watch requires a 21mm strap, see our Watch Strap Sizing Guide.
