Cut and stitched in Milano, in the width this watch takes.
Sizing notes
- Any 20 mm band fits this reference, in leather, rubber or fabric.
- Inside the Heritage family the lug width is not one number: it runs 14, 15, 18, 19, 20, 21 mm. This reference is the 20 mm one, so a band bought for another Heritage 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 →
