Watch Strap Size Guide

Measuring Lug Width

The lug width is the distance between the watch lugs where the strap attaches. To find your lug width:

  1. Remove the current strap
  2. Measure the gap between lugs in millimetres using digital callipers or a ruler
  3. Common lug widths are 18mm, 20mm, 22mm, and 24mm but some watch models use odd-numbered sizes.

For most accurate results, use digital callipers. If using a ruler, ensure it's thin enough to fit between the lugs and take care to measure at the exact point where the strap sits.

If you can't remove the strap, measure your current strap's width at the point where it meets the watch case. If the lug width is 20mm, then you should order a 20mm strap.

Strap Length

Standard strap lengths:

  • Small (for 5.5-6.5" wrists): 105/65mm
  • Regular (for 6.5-7.5" wrists): 115/75mm
  • Long (for 7.5"+ wrists): 125/85mm.

The first number indicates the length of the longer piece (with the holes), whilst the second number is the shorter piece (buckle end).

Tip: If unsure, measure your current strap from end to end while laid flat. Order the same total length or slightly longer if you're between sizes.
