Will a strap close on your wrist?
Set for this watch: 46 mm of case and 24 mm between the lugs. Add your wrist and see where a standard strap would close.
mm
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
- 24 mm is the gap between the lugs, so a 24 mm band goes in without adapters. Whether it sits flush against a 46 mm case depends on how that case is shaped.
- 24 mm is not a common size: only 2,192 of the 41,485 watches measured take it (5.3%), so ready-made choice at this width is narrower than at 20 or 22 mm. Every watch that takes 24 mm →
