Will a strap close on your wrist?
Set for this watch: 23 mm of case and 6 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
- 6 mm is the gap between the lugs, so a 6 mm band goes in without adapters. Whether it sits flush against a 23 mm case depends on how that case is shaped.
- Inside the PrimaLuna family the lug width is not one number: it runs 6, 8, 9 mm. This reference is the 6 mm one, so a band bought for another PrimaLuna may not fit it. Why the size changes inside a family →
