The computer technology of Garmin is stable, reliable, and lasts forever. I used this watch for running, cycling, swimming, xc skiing and many other workouts. I upgraded and no longer need this one but would highly recommend for anyone looking for a great watch. It easily connects to all phone's. *Note: there are a nicks on the watch edge that don't affect the functionality.
