Will a strap close on your wrist?

Set for this watch: 40 mm of case and 19 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

19 mm is the gap between the lugs, so a 19 mm band goes in without adapters. Whether it sits flush against a 40 mm case depends on how that case is shaped.
19 mm is an odd size: most ready-made bands are made in even widths, so this reference needs one cut to measure or a band that runs in odd sizes. Why some watches take odd sizes →
Inside the Harmony family the lug width is not one number: it runs 18, 19, 20, 22, 23 mm. This reference is the 19 mm one, so a band bought for another Harmony may not fit it. Why the size changes inside a family →
19 mm is not a common size: only 1,919 of the 41,485 watches measured take it (4.6%), so ready-made choice at this width is narrower than at 20 or 22 mm. Every watch that takes 19 mm →
