I've had mine about 3 weeks now, and it has been an interesting experience. I like being able to keep tabs on emails and texts, and especially using it as a hands-free phone. Everything works great, and the battery lasts at least two days. I haven't tried going beyond that.

Excellent design with the outer ring of the watch face allowing you to navigate through the various watch options and widgets; Clear bright display with a decent battery life although I would still recommend charging as often as possible as using all wireless functions (GPS, Bluetooth etc) would...

A little easy to scratch so care is needed when wearing

I'm sure there are many features that still need to happen. I'm sure there are developments yet to be made. But aside from obvious pie in the sky pure sci-fi lunacy like motion capture for VR or augmented reality applications, I can't think of anything that's even remotely attainable.

Bright display; Durable; simple usability; "interface feel" extremely satisfying; the freaking watch dial rotates how cool is that

not enough apps; so much utility potential as yet untapped..

The Gear S3 Frontier is a great-looking smartwatch that truly lets you leave your phone at home.

Rotating bezel looks good and works great; Built-in LTE makes it phone independent; Samsung Pay works at MST terminals

Size will be too big for some wrists; App support lacking; Battery life could be an issue for some users

With the Gear S3 Frontier, Samsung did a commendable job building a wearable with a little something for everyone. The device still falls short in a lot of ways, including its overzealous automatic fitness tracking and a limited app selection, even after a year.

Still has the best smartwatch interface; Excellent performance; Respectable battery life; OLED display is bright and crisp

Not many good Tizen apps; Automatic exercise tracking can be weird; Will be too big for some

Smartwatches are experiments. For a taste of the future, you've got to live with compromise on your wrist. But for a lot of people, connected watches are best kept simple. Battery life wins out over tons of features, and ease of use over feature bloat. After all, that's what phones are for. Watches are where we check things quickly.

Samsung's watch survives, for now, as one of the better options for Android phone users.

Well-constructed; attractive design; clever spinning bezel interface. GPS, speakerphone, optional stand-alone LTE phone service and work-anywhere Samsung Pay. Spotify app streams music on the go. Works with most Android phones, and even iPhones to a degree.

It's big; Tizen-based software has less app support than Apple Watch or Android Wear; iOS connection works, but it's very buggy; Few killer apps take advantage of stand-alone LTE services.

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 $349 Samsung Gear S3 Frontier is the first smartwatch that promises a fully untethered experience.

Handsome and durable design; Built-in LTE; GPS; Samsung Pay; Good voice control

Very limited app selection; Heavy

The Gear S2 arrived on a deserved wave of hype, but for some reason we aren't overly excited about this new Gear S3 Frontier. The only thing it actually adds is GPS, and at a £100 cost it'll definitely put some people off.

The Gear S3 Frontier is absolutely attractive, looks catchy and is certainly way ahead of all the smartwatches currently available in the market. In short, with Gear S3 Frontier Samsung has nailed the basics and there are certain features here that are unavailable on other smartwatches.

Premium look; Beautiful and durable design; good call quality; good voice control; S Health

Lack of apps; heavy

I'm blown away by how good this watch really is. Presentable packaging, amazing charging features, the magnetic base is a nice touch. Very easy to use, connects easily to my samsung galaxy s8 and records and keeps track of everything. I had to leave my watch home today, and I feel naked without it.
