Samsung Smartwatches Gear S3 - Wearables | Samsung US. I have both Gear S3 Frontier and Classic Smartwatches. I got the Classic both for styling, and because it has an LTE phone chip in it. But, these watches are still under $400 and the ability to change watch faces on a whim, and the regular software updates make them new again all the time. Even if you are a watches are just to tell time person, you probably paid a couple of hundred dollars for the one on your wrist. A watch that gently vibrates on your arm to remind you of calendar events, an incoming text, email or phone call, and that can measure your steps, heart rate, and much more, is certainly well worth another couple of hundred dollars. If you are concerned about microwave radiation in cell phones, taking a call on your watch is a no brainer.
