You can choose more than one option. FREAKS. ;-)
Help me choose, for the vote:
When I'm working in the yard (and know I'm not gonna' bang my wrists against something hard), I'll either: 1) wear two of three Citizen Eco-Drives on each wrist if the weather's particularly sunny; or 2) an auto'-wind on each wrist if I haven't worn either for a while.
When I had more autos than I did winders (the former still not a lot; and at the time I had 0 winders anyways), I would wear my fav' model at the time and carry one auto in one front pocket of my pants and another in the other front pocket. Wearing, technically, yes, three watches at one time (time to call Ripley's?).
Heh, 'zat what you're looking for?
I don't know if this practice is necessarily in public or private. My place, private, I guess, but, can see in from the street. So, I dunno.
