Suunto Vector.
You've got the regular watch (chrono, timer, alarms, calendar...), plus :
- altimeter
- barometer
- digital compass (0,5 degrees precision)
That's what I use and it's great. Nice big digits. Great light. Works well with a 5 meters resolution (more than enough). As every altimeter, it's relying on athmospheric pressure, so when weather changes, the altimeter's screwed up by a few meters. That's true for all altimeters that rely on air pressure... The vector is a nice one. Best thing is that you don't have to send it back to the company to have the battery changed (unlike many other models).
A great thingy about the vector is the ascent/descent rate you can read onit while on altimeter function. I use this a lot when hiking with people that are less in shape than me. I find their ascension rate and I stick to it with the help of the watch.
Cheers,
