Combines the classic look of an analog watch but adds the functionality of a smartwatch. The watch can use vibrations and hand movements to alert you of app notifications, calls, and texts from your phone. Built-in activity tracker, calories burned, distance, and sleep patterns. Compatible with Android OS50 and IPhone 9. Via Fossil Q App I just replaced the Battery…..that was $20… I didn’t use this much, don’t have original box or directions. It looks lovely on!
