A simple, but not so ordinary analogue watch (Score 1)

I'd sugest you have a look at the Citizen Eco-Drive watch. I've got the very simple looking titanium diver's version (AP0600-01E). which looks like a British Army watch of old. It runs forever as long as it gets a bit of sun and you're not deeper than 200m underwater. The whole face is a solar panel and the watch is completely sealed - the back is flat with no opening at all - containing a Li-ion battery, I believe. Mine's 2 years old and it's reisted every attempt to dent or scratch it. It's geeky, but subtle geeky.
