Will a strap close on your wrist?
Set for this watch: 45 mm of case and 23 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
- 23 mm is the gap between the lugs, so a 23 mm band goes in without adapters. Whether it sits flush against a 45 mm case depends on how that case is shaped.
- 23 mm is an odd size: most ready-made bands are made in even widths, so this reference needs one cut to measure or a band that runs in odd sizes. Why some watches take odd sizes →
- Inside the Pilot family the lug width is not one number: it runs 18, 20, 22, 23 mm. This reference is the 23 mm one, so a band bought for another Pilot may not fit it. Why the size changes inside a family →
- 23 mm is not a common size: only 655 of the 41,485 watches measured take it (1.6%), so ready-made choice at this width is narrower than at 20 or 22 mm. Every watch that takes 23 mm →
