Does the ScanWatch 2 38mm fit your wrist?
The 38mm suits wrists of about 13.5–19.5 cm round; the 42mm, 15 cm and up. Both work from 15 to 19.5 cm, where it is a choice between more skin either side (the 38mm) and a case that fills the wrist (the 42mm). Under 15 cm only the 38mm's lugs stay on the wrist; over 19.5 cm the 38mm starts to look small.
