Will a strap close on your wrist?
Set for this watch: 36 mm of case and 18 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
- 18 mm is the gap between the lugs, so a 18 mm band goes in without adapters. Whether it sits flush against a 36 mm case depends on how that case is shaped.
- Inside the Grand Complications family the lug width is not one number: it runs 16, 17, 18, 19, 20, 21, 22 mm. This reference is the 18 mm one, so a band bought for another Grand Complications may not fit it. Why the size changes inside a family →
- 18 mm is not a common size: only 3,965 of the 41,485 watches measured take it (9.6%), so ready-made choice at this width is narrower than at 20 or 22 mm. Every watch that takes 18 mm →
