"Alterra watch" - Review of Highgear Alterra Altimeter Watch

Programming this watch is pretty difficult, you do not want to set a certain barometer and also the altimeter. Once you have the correct barometer set then the altimeter is fairly accurate. If you want to watch to remain accurate the barometer has to be updated fairly often, about twice a week. I would recommend updated it right before you head out to use it to be the most accurate. There are a lot of nice features on this watch though, graphs of barometric pressure and change in altitude is really nice. Also an altimeter alarm so you know when you hit certain height with out having to always look at the watch. The thermometer is very accurate also. The watch is water resistant to 50 meters, but anyone who would need a watch like this would love to see it be waterproof. The customer service was great though when I had a question about how to initially set the watch functions.
