I haven't worn a watch in what must be fifteen years now. But, if I was to wear one, it would be something like:
Kinetic Chronograph
or
Kinetic Perpetual
They are geeky, powered by humans, and are reasonably simple looking.
As mentioned, you could also try Citizen's Eco-Drive watches. I checked the site, some have titanium straps and most seem to have anti-reflective sapphire glass.
