Sizing notes

  • Any 20 mm band fits this reference, in leather, rubber or fabric.
  • Inside the Alpinist family the lug width is not one number: it runs 18, 19, 20 mm. This reference is the 20 mm one, so a band bought for another Alpinist 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 →
