I like vintage watches and have girlie wrists, my sweet spot is 36 - 40mm. I have an Omega I picked up a few years ago, solid rose gold case and very pretty, but feels too small at 30mm. I have a small collection of military watches and some of the early ones are tiny by modern standards. I have three working WWI trench watches and some parts and projects. By random chance I have two the same and of that pair the one in less good condition gets fairly regular wrist time.
Large, I’ve grown to like 44mm Pams, I have a couple at 47, but feel a bit self conscious in them. I have a B-uhr homage. 55mm. Even the strap is so big, I could probably wear it around my thigh. It was designed to go over gauntlets though.
