Bands that fit
Cut and stitched in Milano, in the width this watch takes.
Sizing notes
- Any 16 mm band fits this reference, in leather, rubber or fabric.
- Inside the Tank Must family the lug width is not one number: it runs 16, 19, 23 mm. This reference is the 16 mm one, so a band bought for another Tank Must may not fit it. Why the size changes inside a family →
- 16 mm is not a common size: only 3,009 of the 41,485 watches measured take it (7.3%), so ready-made choice at this width is narrower than at 20 or 22 mm. Every watch that takes 16 mm →
