About 20mm watch straps

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.

20mm Watch Strap Questions

What watches take a 20mm strap?

Lots of men's watches with cases around 38–42mm, including plenty of divers, field watches and dress watches. Case size is only a rough guide, though; the lug width is what counts, so it's always worth measuring.

Do the straps come with spring bars?

Yes, every strap does. Quick release straps come with quick release spring bars.

Will a 20mm strap fit my 20mm lugs?

Yes. The width is measured where the strap meets the watch, so a 20mm strap fits a 20mm gap between the lugs. Most straps narrow towards the buckle, and each strap's size guide shows its width at the buckle.

Do your straps come with spring bars?

Yes, every strap comes with spring bars. Quick-release straps have quick-release spring bars fitted, so you can swap them without a tool.
