Find your lug width
Lug width is the distance between the inside edges of your watch lugs — the gap where the strap sits. Measuring correctly ensures a snug, secure fit.
How to measure
- Remove the current strap from your watch.
- Use a ruler (mm) or caliper to measure the gap between the inside edges of the two lugs.
- Note the measurement in millimetres and select the matching width when ordering.
