Agreed, a watch is a kind of fire-and-forget item: it has to work when you need it and to be forgotten the rest of the time!!! If I need to charge it every night (even every week), I won't use it. But maybe I'm not geek enough... Moreover, I don't see enough added-value in this kind of devices right now. BTW... isn't it possible for that kind of devices to recharge like "forever" watch, only by the move of the hand?
