Bands that fit

Cut and stitched in Milano, in the width this watch takes.

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 Speedmaster family the lug width is not one number: it runs 18, 19, 20 mm. This reference is the 19 mm one, so a band bought for another Speedmaster 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 →
