$100 · Samsung Gear S3

Can you finally leave your smartphone at home? With its own LTE, heart-rate monitor, Wi-Fi and GPS — not to mention mobile payments and voice control — the Samsung Gear S3 Frontier is the first smartwatch that promises a fully untethered experience. This timepiece also happens to be gorgeous and pretty durable. The Gear S3's stainless-steel case is attractive. I especially liked the serrations on the rotating bezel, which not only look great but make it easier to turn. It looks the part of a high-end timepiece.
