18mm Watch Strap Questions

18mm is one of our biggest ranges, with over 500 straps. Most are leather, from smooth calf to alligator, croc and lizard grain, alongside handmade straps for something special. For everyday wear and the outdoors, nylon and military-style straps are hard-wearing, and waterproof options cope with swimming and the gym. If you swap straps often, our quick release straps change in seconds without a tool.

Not sure 18mm is right? Measure between the lugs where the strap attaches. Our guide to measuring a watch strap shows you how. Between sizes? Have a look at 17mm, 19mm or 20mm.
