Skip this step. We’ll automatically add the correct {clasp}mm clasp to your cart based on the strap size you select (you can change it in cart).
If you’re using your own clasp, here’s how to find your size:
Method 1
Measure the width of your current strap at the clasp end in mm). Label top part of strap lug end, and bottom part clasp end
Method 2
Measure the inner opening of your clasp; or your current strap where it meets the clasp with a ruler/caliper (mm).
Tip:
Make sure the strap’s second number equals your clasp size.
Examples:
20/18mm → fits a 20mm watch lug and 18mm clasp; 22/20mm → fits a 22mm watch lug, and 20mm clasp.
