Should you take a 38mm or a 42mm?
Most jewelers and watch specialists would argue that a wrist size between 15.3cm (or 6") and 17.8 cm (or 7") would suit both a 38mm and a 42mm.
This means, that if your wrist is smaller than 6", the 38mm is the best fit for you. If your wrist is significantly larger than 7" however, most would advise going with the 42mm.
