[curious] what's your watch for the rough stuff?

I recently bought my first mechanic watch after having my Tissot v8 for a long time. I wear one of those every day but I still leave them at home for the gym, mountainbiking or ski mountaineering. As I first of all do wear a watch to tell me the time, I would like to get a "beater" how some of you call it. Something that can take some hits, wears lightly and still looks good. I'm thinking of a quartz chronograph, but I wonder what you guys wear for these occasions.

Show me your beater watch.
