Sizing notes

  • 24 mm is the gap between the lugs, so a 24 mm band goes in without adapters. Whether it sits flush against a 43 mm case depends on how that case is shaped.
  • Inside the Eco-Drive family the lug width is not one number: it runs 6, 7, 10, 12, 13, 14, 15, 16, 18, 19, 20, 21, 22, 23, 24, 26 mm. This reference is the 24 mm one, so a band bought for another Eco-Drive may not fit it. Why the size changes inside a family
  • 24 mm is not a common size: only 2,107 of the 39,834 watches measured take it (5.3%), so ready-made choice at this width is narrower than at 20 or 22 mm. Every watch that takes 24 mm
