Other features include app-based auto time setting correction and other features for more efficient timekeeping, and an Auto LED Light to facilitate workouts in areas where lighting is dim. Back wings on the inside of the bands where they connect to the case, a new band ring shape that prevents sliding, and more band holes to allow better tightness adjustment, all add up to a more comfortable fit.
