FYI, here are two 42 mm case watches (OK, one is a cutout) Wrist size is about 177mm. Most watches I know of quote the bezel diameter rather than the case size. The Apple, of course, is almost all crystal.
Still might go 42 for readability and battery, but will look at the 38 in real life before I order.
