Sizing notes

  • 20.05 mm is the gap between the lugs, so a 20.05 mm band goes in without adapters. Whether it sits flush against a 42 mm case depends on how that case is shaped.
  • Inside the Chronomat family the lug width is not one number: it runs 16, 18, 20, 20.05, 22 mm. This reference is the 20.05 mm one, so a band bought for another Chronomat may not fit it. Why the size changes inside a family →
