Watch strap size guide
Every watch has a lug width — the gap between the lugs in millimeters. Get the right size and you'll find thousands of AliExpress straps starting at $3.
How to measure your lug width
Measure the gap between your watch's lugs with a digital caliper or a ruler. The number in millimeters is your lug width. You can also look up your watch model online — the lug width is always listed in spec sheets. Common sizes are 18mm, 19mm, 20mm, 22mm, and 24mm.
