20mm Watch Strap Questions

Most of our 20mm range is leather, from smooth calf and suede to croc and alligator grain, so there's something for a dress watch and something for every day. If you like to switch your look, our quick release straps change in seconds without a tool. For the gym, the beach or a wet walk, silicone and nylon cope with water and sweat. And if a standard strap doesn't quite reach, try an extra long version. You can also browse all our men's watch straps or ladies' watch straps.

Not sure 20mm is right? Measure between the lugs where the strap attaches. Our guide to measuring a watch strap shows you how, and which way round a strap goes covers fitting it. Between sizes? Have a look at 19mm, 21mm or 22mm.
