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
- 22 mm is the gap between the lugs, so a 22 mm band goes in without adapters. Whether it sits flush against a 40 mm case depends on how that case is shaped.
- 22 mm is one of the common sizes: 6,971 of the 41,485 watches measured take it, which is why it is the width most bands are cut in. Every watch that takes 22 mm →
