Compatible with Android and iOS, Samsung is surprisingly open-minded with its selection of supported smartphones with the Gear S3, but it very much works to its favor.

The Gear S3 is an improvement on the Gear S2 in all ways but one: the design. Or at least we think so; you might disagree and prefer that bigger, bunkier look. While it might look more like a classic watch than the S2, it's also much bigger - 46mm wide.

However that larger body affords it a screen where Tizen can really shine, and a bigger battery, from which we've managed to squeeze an average of three days from - much better than anything in the Android Wear stable or from the Apple Watch. Like the Apple Watch, Samsung treads between smartwatch and fitness tracker, also packing in a heart rate sensor along with that GPS and its much-improved Samsung Health software. There's the option of LTE too if you wish for an untethered connection, with a standalone speaker for taking calls on the watch.
