I love this watch. You can track most sport on it, including swimming which was a must for me as it tracks pace, stroke, efficiency and effort (continuous heart rate monitoring). It alsp has GPS so can track any runs that you do.You can connect apps easily and customise the look of the watch easily too.One thing I really like is the fact you can download your Spotify account allowing you to use bluetooth headphones whilst out running/at the gym without the need for carrying your phone around. Messages don't work without phone nearby though.The watch also looks really sleek, i think its really stylish. Its very comfortable, I forget I'm wearing it most of the time.The only areas where there are downfalls for me are that you don't get messages unless connected via Bluetooth (although I know this would require the watch to be connected to a network of its own, so isn't very practicable). The other thing is the battery life, it can probably go about a day and a half without charging but I charge it every night as I don't track my sleep so it's never been an issue for me.If you're looking for a stylish watch that has a huge number of features to help you track your fitness and sporting activities, this is the watch for you.
