Nice! Eco-Drive.... she must really like you!!!
I recieved a Citizen Eco Drive from my boss last summer when I started bar-tending.
It'* a little bit of a nuisance to wear, but I love it. No batteries, no winding.
One thing sucks though about mine -I scratched the face right in the center back in October and it'* been bugging the hell out of me.
eco-drive run off of any light source, not just the sun.
the ones that wind from the movement of your hand are annoying, if you dont wear it for awhile, its annoying as h*ll to recharge. and even so, theres no guarantee that its charging while youre walking because its so particular.
my fiance'* eco-drive doesnt work any more. it lasted for 7 years. the one she got me is still running strong though.
