Tom Cox wrote a review of Suunto Vector Altimeter Watch on September 16, 2014
Familiarity: I've used it several times
Compared to the Highgear (which is no longer made) this watch stands alone. I've used it on several mountaineering, backpacking and climbing trips and it has yet to fail in any way.
Alarm: Loud enough to wake me up.
Altimeter: Easy to adjust and fairly accurate.
Barometer: Also easy to adjust and use.
Compass: Is also easy to read, use and calibrate.
Data Logs: Haven't really used but they do work and it's pretty cool.
Time: Hey, it also keeps time and date!
Size: Big, but not too big. It is also light on the wrist and looks great.
