That said, wristwatches are generally very very long lived. I own a Citizen marinaut which is powered through a solar cell in the face of the watch. I've been wearing it pretty much every day for 15 years now and I never had to charge or service it. Only the occasional shortening of the metal wristband.
I find on cheaper watches like this the band eventually breaks, and you can't really find replacement bands which are much cheaper than a whole new watch.
