Aaron Robertswrote a review of Suunto Core Altimeter Watch on April 18, 2010
I bought this watch a little over a month ago and it has gotten quite a bit of use in that one month. Living in Utah in Spring, you get a lot of opportunity to ski and hike. I got to put this to the test. All in all, there is nothing negative I can say about this watch. The Altimeter works great, very little discrepancy from the actual altitude (as long as the weather holds). It is very easy to change the reference points though so if the Barometric Pressure does change you can get it reference again very easily. I love the Storm Alarm feature, I was hiking in southern Utah a few weeks ago in some slot canyons and couldn't see the sky. Suddenly my watch started beeping and I was able to see that a storm was approaching. I was able to get out before it started raining which was great. The alarm is quite loud for such a small unit. 100% waterproof, me being the gear junkie I am, I tested this out. I submerged it for around 5 minutes and there were no problems with water getting into the housing. The only really negative thing (which isn't a big deal) is the strap on the one I got. I know I'll have to replace it soon as it's already starting to show some signs of wear, with me wearing it pretty much 24/7. not a big deal though, the replacements are cheap. Battery life has been immensely improved in the newer models. I've seen complaints about the thermometer not working either...you need to take it off of your wrist for it to be accurate. If not it will just pick up the heat from your body and give an inaccurate reading. All in all, the best altimeter I've ever used.
