Sizing notes

  • 18 mm is the gap between the lugs, so a 18 mm band goes in without adapters. Whether it sits flush against a 38 mm case depends on how that case is shaped.
  • Inside the Seamaster Planet Ocean family the lug width is not one number: it runs 18, 19, 20, 21, 22 mm. This reference is the 18 mm one, so a band bought for another Seamaster Planet Ocean may not fit it. Why the size changes inside a family →
  • 18 mm is not a common size: only 3,965 of the 41,485 watches measured take it (9.6%), so ready-made choice at this width is narrower than at 20 or 22 mm. Every watch that takes 18 mm →
