Bands that fit
Cut and stitched in Milano, in the width this watch takes.
Will a strap close on your wrist?
Set for this watch: 40 mm of case and 20 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
- 20 mm is the gap between the lugs, so a 20 mm band goes in without adapters. Whether it sits flush against a 40 mm case depends on how that case is shaped.
- Inside the Heritage Collection family the lug width is not one number: it runs 13, 20, 21 mm. This reference is the 20 mm one, so a band bought for another Heritage Collection may not fit it. Why the size changes inside a family →
- 20 mm is one of the common sizes: 15,081 of the 41,485 watches measured take it, which is why it is the width most bands are cut in. Every watch that takes 20 mm →
