Will a strap close on your wrist?
Set for this watch: 43 mm of case and 22 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
- 22 mm is the gap between the lugs, so a 22 mm band goes in without adapters. Whether it sits flush against a 43 mm case depends on how that case is shaped.
- Inside the Sport Luxury family the lug width is not one number: it runs 18, 20, 22, 23 mm. This reference is the 22 mm one, so a band bought for another Sport Luxury may not fit it. Why the size changes inside a family →
- 22 mm is one of the common sizes: 6,021 of the 39,834 watches measured take it, which is why it is the width most bands are cut in. Every watch that takes 22 mm →
