Bands that fit
Cut and stitched in Milano, in the width this watch takes.
Sizing notes
- Any 18 mm band fits this reference, in leather, rubber or fabric.
- Inside the Speedmaster family the lug width is not one number: it runs 18, 19, 20 mm. This reference is the 18 mm one, so a band bought for another Speedmaster 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 →
