If you know the exact model of your watch a quick google search will usually reveal your watches lug width. Alternatively measure the width of your old strap at the point closest to the spring-bars or measure the distance between the lugs. If you are unsure, drop us a line at hello@notostrapstore.com. If you do order the wrong size by mistake, don't worry just pop it back in the post to us and we will swap it for the correct one for you.
