watch purchased in February 2015, amateur level, practice swimming and running (3 times per week). Positives: good wife she ergonomics wrist, wide bracelet is comfortable to wear, it is light and well finished. Its GPS is effective, the satellite capture is done quickly (QuickGPS) for me it captures even indoors. Cardiopulmonary function works perfectly and provides you wear a chest strap while running. Aesthetically I find it pretty, it is not too thick, the screen is visible even with strong sunlight. Bad: tristounet screen (no colors), obligation to go through the internet to transfer the clock data on the computer, the site is poorly designed tomtom: you will feel good only forum dedicated to shows, I ' asked a technical question there 10 days and no response from staff, other users also complain about the lack of responsiveness of the mark with respect to its users. On the show you can put 3 data on one screen, though the 2 data from the top of the screen are too small for the rest you have to scroll: I would have preferred a screen cut into four for example. For indoor swimming sessions careful to have a smooth and regular swimming and clearly mark your stops when you get in the end if the watch adds lengths and no opportunity to correct the error on the spot when you remember which is quite annoying: suddenly we check each length counting is good which limits the value of the watch for coup..pour sixty lengths I have a margin of error of 10 and 15 lengths if we are many on the water line, much less when there are fewer people. The GPS does not work in swimming mode even outside the distance is calculated based on the number of swimming pool lengths calculated by the watch. In the end I am satisfied with this watch for its fast and accurate gps and his cardio. Its price seems well placed me in view of the competition. By cons for swimming, the website and forum the brand still has progress to make. A color screen would also be welcome there I sometimes feel my casio watch for it 20 years ago ..
