Bands that fit
Cut and stitched in Milano, in the width this watch takes.
Sizing notes
- Any 21 mm band fits this reference, in leather, rubber or fabric.
- 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 →
