I've got a Seiko 5 watch with Military Blue Strap, you can get one with metal strap - but I personally prefer the more casual look. Anyway, they can be had for around 30 to 40quid. Fully automatic, great price, great built quality. I've got one for over a 14months so far and still loving it.
Not too expensive that you've got to baby it either.
Only downside about kinetic Automatic watches are, if you stop using it, the spring will unload and stop ticking after awhile. In the case of the Seiko 5, it's about 48 to 60 hours. I put mine on pretty much everyday so no issue there.
