Sizing notes

  • 28 mm is the gap between the lugs, so a 28 mm band goes in without adapters. Whether it sits flush against a 53 mm case depends on how that case is shaped.
  • Inside the ProMaster family the lug width is not one number: it runs 18, 20, 22, 27, 28, 29 mm. This reference is the 28 mm one, so a band bought for another ProMaster may not fit it. Why the size changes inside a family
