Will a strap close on your wrist?

Set for this watch: 41 mm of case and 20 mm between the lugs. Add your wrist and see where a standard strap would close.

Your wrist

Watch length, lug to lug

Filled in with the case diameter, which is what we hold for this reference. Measure the watch tip to tip for the exact answer: it is usually a few mm more.

Enter your wrist measurement to see whether a standard 75/115 mm strap closes on you, and where.

Sizing notes

20 mm is the gap between the lugs, so a 20 mm band goes in without adapters. Whether it sits flush against a 41 mm case depends on how that case is shaped.
Inside the Defy Skyline family the lug width is not one number: it runs 18, 20, 22 mm. This reference is the 20 mm one, so a band bought for another Defy Skyline may not fit it. Why the size changes inside a family →
20 mm is one of the common sizes: 15,081 of the 41,485 watches measured take it, which is why it is the width most bands are cut in. Every watch that takes 20 mm →
