Will a strap close on your wrist?
Set for this watch: 25 mm of case and 13 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
- 13 mm is the gap between the lugs, so a 13 mm band goes in without adapters. Whether it sits flush against a 25 mm case depends on how that case is shaped.
- 13 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 Flagship family the lug width is not one number: it runs 10, 12, 13, 15, 16, 18, 20, 21 mm. This reference is the 13 mm one, so a band bought for another Flagship may not fit it. Why the size changes inside a family →
- 13 mm is not a common size: only 487 of the 41,485 watches measured take it (1.2%), so ready-made choice at this width is narrower than at 20 or 22 mm. Every watch that takes 13 mm →
