Great durable multifunction watch.

Voted 5/5

I bought this primarily to use only in the outdoors, however once putting it on it's now on my wrist all the time. The watch is very durable, in the four years of use it's held up very well. The altimeter functions via barometer, so some adjustment will be needed, however once calibrating at known altitudes at the beginning of each hike/climb, it's very simple to check altitude along the way with fairly accurate readings.

The main gripe about this watch is that every 3 years on average you will have to replace the 4 lithium batteries the watch requires. Since this watch is water-resistant, this means that you will have to take the watch in to a service center to have it re-sealed. On average the battery replacement is around $30 to $40. Otherwise this is a great watch.
