The Samsung Galaxy Watch3 is a great smartwatch that is thinner and feels almost like a premium device. There are some sacrifices you’ll have to make, like not as long of battery life as previous watches and a fairly substantial price increase.

  • +

    Slimmer, lighter than the original, Great display, The rotating bezel is intuitive, Solid two-day battery life, Fast performance, Tizen still works well as a smartwatch OS, Good fitness tracking features

  • -

    Battery life is shorter than the previous Galaxy Watch, No MST for Samsung Pay (but there is NFC), Blood pressure and ECG features not available in Canada yet, More expensive, Limited third-party app support

Short battery life is my chief complaint. While the advertising photos of the watch look terrific, in real life, the watch faces definitely look flatter (2D) and less realistic than the marketing images look, so that was a slight disappointment.

Look, I really like this device. But this is the T-Mobile review.T-Mobile has gone the route of pausing updates for this device for the forseeable future.Since it's been so long since the last update, I'm going to return the watch after the weekend.

I'm four days in with the watch and I'm very satisfied with the upgrade from my Gear S2. Samsung has added some nice features to the health options, and improved an alreay good excercise capability.

The watch works as it should but if you are heavily tattooed in your wrist area it will not detect that it is on and will not work correctly I've talked to many other people who have had the same issue so you cant have the only send notifications when on wrist turned on but like i said works...

The Watch 3 had exceeded my expectations. I did not want to have to purchase an additional phone line for the watch because my phone is always with me. If your phone is always with you, then the bluetooth version of the Watch 3 will satisfy your needs.

I love the style, looks, and the function this was has. Great price, especially compared with other brands. Anyone looking for a smart watch, I would recommend this Samsung watch!

Love this watch, battery life could be better. Wear it every day.

5 April 2021

This is very good smartwatch. Both the os-Tizen and battery life fared better than I had thought. However, when it comes to fitness tracking- this watch disappoints. Continuous heart rate tracking is very inconsistent and even the default auto fitness tracker frequently pauses when your right in the...

I have had a couple of Garmin watches and switched from Samsung due to the Gear not being able to keep heart rate. It is great that this one seems to do everything the Garmin did for me but much more interactive with my phone. I do wish I could get more than 3 days on a charge.

6 May 2021

Really like this watch, although 2 frustrations ...1 - I got the watch for primarily heart health monitoring and it's nearly impossible to get a good ECG reading as it always comes back as 'inconclusive', and if it has a blood pressure reading, I have yet to figure out how to get that.
