The watch is comfortable, with a large display screen, making it easy to see the time.
Initially the watch is confusing to operate, however with practice it becomes second nature.
When in exercise mode, measuring your heart rate if you're not running, but doing strength exercises such as push ups and pull ups etc. the movement of your wrists against the buttons generally turns the exercise mode off. This is a disappointing feature.
Whilst running, there is no feature for the watch to take lap times, a basic functionality I assumed the watch has.
Further to this, the watch does not contain a stop watch unless you enter the exercise mode. Another feature I find quite disappointing.
The application suunto uses (movescount.com) is extremely basic, with minimal functionality. One may as well not use it.
However, when entering exercise mode, ones heart rate is picked up relatively quickly and I believe it to work quite accurately.
Overall this watch is extremely basic. It does what you need it to do - Tell the time, monitor your heart rate, and times your exercise duration.
If you're new to heart rate monitors and are seeking a basic heart rate monitor, I would recommend this watch, however for the same price I'm sure you can get better watches with more functionality.
