Bands that fit
Cut and stitched in Milano, in the width this watch takes.
Sizing notes
- Any 19 mm band fits this reference, in leather, rubber or fabric.
- 19 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 →
- Inside the Prospex family the lug width is not one number: it runs 16, 19, 20, 21, 22 mm. This reference is the 19 mm one, so a band bought for another Prospex may not fit it. Why the size changes inside a family →
- 19 mm is not a common size: only 1,919 of the 41,485 watches measured take it (4.6%), so ready-made choice at this width is narrower than at 20 or 22 mm. Every watch that takes 19 mm →
