Does the Galaxy Watch6 Classic Wi-Fi 43mm fit your wrist?

The 43mm suits wrists of about 15 cm and up round; the 47mm, 16.5 cm and up. Both work from 16.5 to 21.5 cm, where it is a choice between more skin either side (the 43mm) and a case that fills the wrist (the 47mm). Under 16.5 cm only the 43mm's lugs stay on the wrist.
