Glad the info helped acdc girl. Can't go wrong with a 410 (or a 405cx depending on price diff & offers for Xmas, other slight difference, 410 comes with the newer hr comfort strap).
Literatin, 210 is a current model, not an old one. Quite a few women at club with a 110 or 210, both are same size... But short some features you might want later on.
It does the basics & main things very well though.
The 4xx models look fine on female wrists too - but you do get a fabric replacement strap with the 405cx (and 410 I think) in the box. Makes it less bulky on some wrists.
The wireless syncing (so no scramble to find a cable) is a big plus to me. Watch doesn't even have to be in the same room, and still syncs sometimes,
