Sizing notes

  • 21 mm is the gap between the lugs, so a 21 mm band goes in without adapters. Whether it sits flush against a 44 mm case depends on how that case is shaped.
  • 21 mm is an odd size: most ready-made bands are made in even widths, so this reference needs one cut to measure or a band that runs in odd sizes. Why some watches take odd sizes →
  • 21 mm is not a common size: only 2,956 of the 41,485 watches measured take it (7.1%), so ready-made choice at this width is narrower than at 20 or 22 mm. Every watch that takes 21 mm →
