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 39.4 mm case depends on how that case is shaped.
  • 20 mm is one of the common sizes: 15,450 of the 39,834 watches measured take it, which is why it is the width most bands are cut in. Every watch that takes 20 mm
