It does everything well that it does. Big screen is easy to see.  Tap screen works in the water for laps. Has reminder features for training.  But it doesnt have the pedometer or the settings for customized workouts for age and weight. The manual is non-existent and if you look it up on line, you may be able to find the right one, but not a the Timex site.  I would have rated this watch 5 Stars if it had a complete and easy to use manual and the features that are described on line.  But for what it is, its a great watch.
