Collection: 20mm

20 mm watch straps

All our straps that measure 20 mm at the case end, in every material. One of the most common lug widths, found on many dive watches and chronographs.

Check that your watch is 20 mm

The lug width is the gap between the two lugs of the case, where the strap attaches. Measure it with callipers, or read the width often stamped on the back of your current strap. The method is in How to measure your watch strap size.

20-18 mm or 20-16 mm: the width at the buckle

The second figure is the width of the strap at the buckle: the smaller it is, the more the strap tapers. In 20 mm we offer 20-18 mm and 20-16 mm. If you reuse your buckle, keep the second figure of your current strap.

Frequently asked questions

What does 20-18 mm mean? 20 mm between the lugs of the watch, 18 mm at the buckle.

Will a 20 mm strap fit 19 or 21 mm lugs? No. On 19 mm it is forced and deforms; on 21 mm it leaves a gap on each side. Take the exact width: 19 mm or 21 mm.

Should I change the spring bars with the strap? Yes if they are bent or if their ends no longer spring out cleanly. Replacement spring bars are chosen by lug width.
