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 39 mm case depends on how that case is shaped.
  • Inside the Ocean family the lug width is not one number: it runs 20, 22 mm. This reference is the 20 mm one, so a band bought for another Ocean 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 →
