Good to know
- GOTCHA: "42mm" means two different things. The 42mm case of Series 10/11/12 takes SMALL-group bands (Apple sells current 42mm bands as fitting 38/40/41/42mm). The 42mm case of Series 1-3 takes LARGE-group bands (Apple: bands for 42mm, 44mm and 45mm cases are compatible with each other).
- A "42mm band" bought new from Apple today is a small-group band: it will NOT fit a Series 3 (or earlier) 42mm watch.
- Small-group and large-group bands are not interchangeable.
