This ultra-thin smartwatch is made by the leading maker of GPS systems, so no doubt it comes equipped with one inside. There's also a built-in sports application with GPS enabled running, biking, golfing, and swimming. The great part is you don't have to have your phone near you to see your stats. The watch gently vibrates with incoming calls, messages, emails, or calendar reminders. The battery power is what hooked us - it lasts up to three weeks with watch/activity tracking and up to 10 hours using GPS.
