For hiking, backpacking and scrambling I like my casio pathfinder, I agree with Nartreb's post, reasonably priced, simple to use, durable and reliable. I had a Suunto but was not satisfied. Suunto's are like the Mercedes or BMW's of watches, whereas Casio's are more on the order of a Toyota or Honda. But it's partly a trick question becuase you really shouldn't wear a wrist watch while doing any technical climbing. I take off my watch and wedding ring when I have to engage my hands/arms with the rock.
