Yeah, it just turns out that all the things that require my wrist to be moving around on top of my desk I do with both hands. Dragging a wristwatch around gets old fast.
I would go as far as saying I am cross dominant, but I certainly have a weird mix in that regard. I tend to take watches off as soon as I am stationary (I've lost a few F-91W's this way). I guess you could just take the watch off when you sit down like myself.
Though to refer to your original comment I don't think you are too concerned either way.
