Sizing Guide
What Is a Lug — and How to Measure Yours
Choosing the right strap starts with one number: your lug width. Get it right and your new strap will fit your watch like it was made for it.
The gap between the lugs = your strap size
Three ways to measure
-
1
Check the spec sheet
Search your watch model + 'lug width'. The manufacturer almost always lists it in millimetres.
-
2
Measure with a ruler
Flip the watch face-down. Measure the inside distance between the two lugs (where the spring bar sits) in millimetres. Round to the nearest even number.
-
3
Measure your old strap
If you have an existing strap, measure its width at the end that meets the case. That's your lug width.
Common sizes
18mm — smaller dress watches · 20mm — most men's watches (Submariner, Speedmaster) · 22mm — larger sport & tool watches
