Will a strap close on your wrist?
Set for this watch: 53 mm of case and 28 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
- 28 mm is the gap between the lugs, so a 28 mm band goes in without adapters. Whether it sits flush against a 53 mm case depends on how that case is shaped.
- Inside the ProMaster family the lug width is not one number: it runs 18, 20, 22, 27, 28, 29 mm. This reference is the 28 mm one, so a band bought for another ProMaster may not fit it. Why the size changes inside a family →
