How to find your Watch Strap Size
You can find your strap size number on the underneath of the buckle end of your leather watch strap.
Look for a two digit number like 18, 20, 21 etc then type this into the “choose option box”.
If you cant see a number e-mail me a picture of the front and back of your watch so we can match the strap to firstname.lastname@example.org
