Tissot T-Touch is a pretty good adventure watch. My complaint is that they seem relatively fragile. I had two of them and they both broke down approx a year after I bought them, after the warranty expired. Good for Tissot, bad for me. After I got them repaired I sold them away to my cousins who were going to University. While they worked, they were fun to use; but they were not robust and didn't work when wet.
The Casio Pro-Trek is a better choice for somebody who will use it in the field. I have a friend that uses one, strap broke but the watch still works.
I agree though, if you are really going to rely on something as important as a compass - it really should be a real separate one. The watch compass is a fallback novelty.
