Does the Uwatch 3 fit your wrist?
The 41.6mm suits wrists of about 15 cm and up round; the 44mm, 15.5 cm and up. Both work from 15.5 to 21.5 cm, where it is a choice between more skin either side (the 41.6mm) and a case that fills the wrist (the 44mm). Under 15.5 cm only the 41.6mm's lugs stay on the wrist.
