About 21mm watch straps

Our 21mm straps are Saffiano Lux leather, with a fine cross-hatched finish that resists scratches and keeps its shape. There are 10 colours, from classic black, brown and grey to bolder blue, red, yellow and orange, so it's easy to dress a watch up or give it a brighter look. Have a look at our premium watch straps for more like this.

Not sure 21mm 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 20mm or 22mm, where you'll find a much wider choice.

21mm Watch Strap Questions

What watches take a 21mm strap?

Some dress and sports watches, usually with cases around 40–42mm. Case size is only a rough guide, though, so it's always worth measuring the lug width.

Can I fit a 20mm or 22mm strap on a 21mm watch?

It's best not to. A strap that's too wide won't fit between the lugs, and one that's too narrow leaves a gap and lets the watch move about. It's worth sticking to 21mm, and if you can't find a style you like, get in touch and we'll help.

Will a 21mm strap fit my 21mm lugs?

Yes. The width is measured where the strap meets the watch, so a 21mm strap fits a 21mm 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.
