Great watch. For running: nothing to say, already a lot of comments about it. I use it a lot for the swimming pool. It sets the distance of the basin: 25 or 50 meters. Mini 20 meters. Possible to keep the heart rate strap provided not to swim too fast. Personally, I do sequences of 45 minutes breaststroke casting, and it can track its progress. Initially, I was 1,500 meters. I am now at 1800 meters. The configuration of the screens on the watch is customizable. We can show what we want during the swimming session. Heart rate, average speed in the 100 meters distance. On PC, you can see the number of movements of basin length arms. It's very precise. Detection of bends is fairly accurate. Between 0 and 2 misses a session. If we mark a pause between each length (1-3 seconds): 0 misses. I appreciate alerts inactivity during the day, and the percentage of activity on the day, week or month. This motivates to play sports, or move. The swimming pool is involved in this activity% provided you have the cardio belt. Synchonisation with PC, and Android / iOS smartphone very easy ... You just press a button for 3 seconds. At the time of the Apple Watch, this waterproof watch has a bright future ahead of her. The update allows you to receive notifications from their iPhone / iPad. By cons, we see only the beginning: the Team or BFM without further detail. So, I deleted. The impact on the autonomy looked very weak air. Moreover, the autonomy of the watch is very good. I recharge on average 1 to week, but I have this weekend about 80%. I think autonomy is therefore envirion one month. We are far from charging 1 / day. For skiing, can do better. The distance is seen. By cons, we can not differentiate rise and fall: so we climb and descent distance. Too bad. It has average speed ascent and descent, maximum speed (downhill course). In short, I've had three months, and I love it. Design great. Maybe a little too thick. Difficult for everyday wear with a shirt, but hey, I'm with.
