Samsung Galaxy Watch 3 buyer’s guide: Everything you need to know



Update: October 2, 2020: We have updated this Galaxy Watch 3 buyer’s guide with details on Samsung’s ECG sensor and a new titanium Galaxy Watch 3. Read on for more details.

Original article: It’s been a couple years since Samsung released its first Galaxy Watch. In that time, the smartwatch landscape has drastically changed. Companies are adding ECGs and oxygen saturation sensors to their wearables, and features we once thought were a far-off future are now commonplace.

Today, alongside the Galaxy Note 20 lineup, the company is finally launching the Samsung Galaxy Watch 3. It’s lighter and much more powerful than the original, and has additional health and safety features that will even give the Apple Watch more competition than before.

Editor’s note: We’ll regularly update this Samsung Galaxy Watch 3 guide with more tips, resources, and details, so stay tuned.

Samsung Galaxy Watch 3 at a glance

Samsung Galaxy Watch 3 The latest and greatest smartwatch from Samsung

The Samsung Galaxy Watch 3 is one of the more versatile smartwatches you can buy. It’s stylish, sporty, comes with plenty of smartwatch features, and has new health sensors that will make the watch better over time.

The Samsung Galaxy Watch 3 is Samsung’s flagship smartwatch for 2020 and the successor to 2017’s Galaxy Watch. While 2019’s Galaxy Watch Active 2 is geared toward, well, active people, the Galaxy Watch 3 is more suited for those who want a smartwatch first and a fitness companion second.

The Samsung Galaxy Watch 3 is for those who want:

  • a versatile smartwatch
  • an alternative to Apple Watch or Wear OS smartwatch
  • a smartwatch that doesn’t skimp on fitness or smart features
  • a wearable to work alongside your Galaxy smartphone

And it may not be a great pick if you need:

  • an inexpensive smartwatch
  • decent third-party app support
  • the most accurate fitness and health sensors

Is the Galaxy Watch 3 worth buying?

Yes, absolutely. If you’re looking for the best smartwatch you can buy that isn’t made by Apple, the Galaxy Watch 3 is it.

It’s one of the most fully featured smartwatches you can get in mid-2020. It has a breadth of fitness tracking features, a good health app, fantastic hardware, equally good software, and onboard music storage with support for popular music apps.

Wear OS is a popular choice for people looking for Android-compatible smartwatches, but Google’s lack of updates leaves us not wanting to recommend any Wear OS smartwatches — at least for the time being. Regardless, the Galaxy Watch 3 has most Wear OS watches beat in many ways, except for lacking third-party app selection.

It’s pricey, though. It starts at $400, with top-end LTE models going up to $479. That’s a high price to pay for any smartwatch. Also, while the Galaxy Watch 3 has many fitness features baked in, it doesn’t track all that accurately. Its GPS and heart rate sensors are still

What reviewers are saying about the Galaxy Watch 3

I’ve already let you know what I think about the Galaxy Watch 3. You should probably buy one, but only if you’re okay with spending hundreds of dollars on a wearable. Here’s what other reviewers around the web are saying about the Galaxy Watch 3.

  • The Verge’s Dan Seifert also praised the Galaxy Watch 3’s rotating bezel and crisp display, as well as its easy-to-use software interface. Overall, though, Seifert drove home the point that the Galaxy Watch 3 isn’t the biggest upgrade compared to previous Samsung watches. He noted that the app selection is still bad, and that fitness features are hit or miss.
  • Engadget’s Cherlynn Low had good things to say about the Galaxy Watch 3, claiming that it’s the best non-Apple smartwatch. She said the watch is chunkier compared to the Active 2, which means it’ll be a bit more annoying to use while working out. She mentioned that fitness tracking has improved over previous watches, and that people on Android looking for non-niche devices like Garmin and Polar watches should probably check out the Galaxy Watch 3.
  • TechCrunch’s Brian Heater said “not many can compete” with the Galaxy Watch 3 when it comes to smartwatches on Android. He also called the rotating bezel satisfying, which many other reviewers seem to agree with. Again, Heater noted the lack of third-party apps in the app store, as well as the Galaxy Watch 3’s bulky design.

What people like you think of the Galaxy Watch 3

We like to hear from you, our readers, when big product launches roll around. It’s clear people are opinionated about Samsung’s Galaxy Watch devices, so we issued a few polls to see how hyped (or how un-hyped) you were before and after the launch of the new Samsung watch.

Back when the Galaxy Watch 3 was just a rumor, we asked you how hyped you were for the watch. Unsurprisingly, the vast majority of AA readers said they were hyped to see Samsung’s next smartwatch. Out of 1,405 total votes, 83.6% said they were excited for the watch, while just 16.44% said they weren’t.

When the Galaxy Watch 3 was just a rumor: How hyped are you for the Galaxy Watch 3?

Things got more interesting after the watch was announced. The $400 price tag was certainly one of the biggest talking points surrounding the Galaxy Watch 3’s unveiling, with many people saying the watch isn’t worth the premium price.

In reality, though, it seems like most people are pretty mixed on whether or not the Galaxy Watch 3 is a good deal. Check out the poll below; just about every option we posed received a nearly equal amount of votes. Many people think the Galaxy Watch 3 is worth the price tag, while others think it’s highway robbery.

Is the Galaxy Watch 3 a good deal?

Samsung Galaxy Watch 3 hardware and design

samsung galaxy watch 3 review display watch face 1

The design hasn’t changed much from the original Galaxy Watch. There are still two sizes to choose from — 41mm and 45mm — and both come with nearly the same specs. The differences, as per usual, are found in the display and battery sizes.

Buy the 45mm Galaxy Watch 3 if you want a bigger smartwatch with a longer-lasting battery. This model has a 1.4-inch AMOLED display and a 340mAh battery, which Samsung says will get you about two days of use on a charge. The 41mm model is smaller and sleeker, but has worse battery life. It comes with a 1.2-inch screen and a 247mAh battery, which Samsung says will get you about a day of use.

Both devices charge wirelessly and can be topped up by Samsung’s Wireless Powershare feature.

Samsung says the Galaxy Watch 3 is 14% thinner than the Galaxy Watch, 8% smaller overall, and 15% lighter. Not bad!

One popular feature that’s returning is the physical rotating bezel. Samsung had a hit on its hands (or wrists?) with the original Galaxy Watch’s bezel, which rotated for easier navigation through the software. The company removed it entirely from the Galaxy Watch Active, then added a pseudo-rotating bezel on the Active 2 that was “rotated” by touch.

You can buy the 45mm Galaxy Watch 3 in Mystic Black and Mystic Silver colorways, and the 41mm Galaxy Watch 3 comes in Mystic Bronze and Mystic Silver. Samsung released a Galaxy Watch 3 variant made of titanium on October 2. It’s only available in the 45mm size, though.

You can get both sizes of the Galaxy Watch 3 with Bluetooth+Wi-Fi connectivity or LTE+Bluetooth+Wi-Fi.

Interestingly, Samsung is keeping these watches powered by its own Exynos 9110 SoC, which is the same processor that powered the first Galaxy Watch. It’s also upping the RAM from 768MB to 1GB and upping the storage from 4GB to 8GB.

Finally, they’re durable. All Galaxy Watch 3s are rated for MIL-STD-810G and IP68+5ATM.

Samsung Galaxy Watch 3 vs Galaxy Watch: What’s new?

Okay, so the Galaxy Watch 3 doesn’t look too different from the original Galaxy Watch. A lot of the big changes are found under the hood.

The Galaxy Watch 3 can track 40 activities, such as running, swimming, and more. It supports automatic activity tracking for seven of those activities, while 33 need to be started manually. During running activities, the watch can give you real-time running analysis and feedback, including asymmetry, contact time, flight time, regularity, vertical, and even how balanced you are while running.

Of course, the new Samsung watch is also equipped with built-in GPS and an optical heart rate sensor. Samsung tells us these are the same sensors that appeared in the Galaxy Watch Active 2. We did have some issues with those sensors, but we’ll withhold judgement until we’re able to test out the Galaxy Watch 3 for ourselves.

Samsung included a pulse oximeter in the Galaxy Watch 3 for recording on-demand VO2 max estimates. You can also see a summary of your SpO2 data in the Samsung Health app.

Sleep tracking is getting a big boost, too. Samsung partnered with the National Sleep Foundation to bring far better sleep tracking and analysis to its new watch. The Galaxy Watch 3 can measure sleep cycles (light, deep, REM) and your total time awake. It’ll also calculate a sleep quality score based on your sleep stages and movements, available in the Samsung Health app.

If you’re wearing your watch to bed for sleep tracking, people who own the 45mm model with the bigger battery might be better off — sleep tracking does use up some juice! If you have the 41mm model and wear it all day you may need to top it up before you go to bed, otherwise you might run the risk of it dying in your sleep.

The pulse oximeter is only able to be used for on-demand readings and general health purposes. It won’t record during sleep tracking, so the Galaxy Watch 3 will not be able to detect signs of sleep apnea like competing products from Fitbit and Withings.

The Galaxy Watch 3 is getting another nice safety feature: trip detection. If the watch’s accelerometer senses that you’ve fallen, you have the option to send a custom SMS to up to four predefined contacts. This will be very helpful for runners who are out on their own, or for older users who live alone.

Samsung is also touting the Galaxy Watch 3’s built-in ECG and blood pressure monitoring, though there’s one caveat: the latter isn’t actually available yet. We aren’t sure when this feature will launch, though it should arrive sometime this year. On September 23, Samsung announced that it enabled ECG functionality on the Galaxy Watch 3 and Active 2 smartwatches. You can read more about that here.

If you happen to own a Samsung TV, the Galaxy Watch 3 will actually be a pretty decent workout companion for staying active at home. You can select a workout on your Galaxy Watch 3 and follow along with a Samsung-made workout video on your television. Samsung says users can select from up to 120 different workout videos.

What about the Samsung Galaxy Watch Active 2?

samsung galaxy watch active 2 review watch face clock face 7

Samsung confirmed that its Active line of smartwatches won’t be going away anytime soon. That means the Galaxy Watch 3 and Galaxy Watch Active 2 will be sold on official retail channels at the same time. Also, we will likely eventually see a Galaxy Watch Active 3.

The Galaxy Watch Active 2 is still a solid sports smartwatch. It’s thinner and more workout-friendly than the Galaxy Watch 3. It only has a touch-enabled rotating bezel, though, as opposed to the much-preferred physical bezel on the Galaxy Watch 3.

The jury is still out as to whether or not the Galaxy Watch Active 2 (and older devices) will get Galaxy Watch 3 features like advanced sleep tracking, though it’s possible. According to Samsung, it all depends on the hardware.

If you find yourself using your wearable for tracking workouts, it wouldn’t be a bad idea to consider the Galaxy Watch Active 2 if you can find it at a discount. However, the Galaxy Watch 3 does offer a solid suite of workout features, so it’s a little too early for us to crown a winner. Stay tuned for a full comparison.

What are some good Samsung Galaxy Watch 3 alternatives?

The Samsung Galaxy Watch 3 seems pretty great, but it’s not going to be the watch for everyone. Here are a few of our recommended Galaxy Watch 3 alternatives:

  • Apple Watch Series 5: This one’s a no-brainer if you have an iPhone. For iOS users, the Apple Watch is hard to beat. It trounces the Galaxy Watch 3 with third-party app support and rivals it in terms of fitness and smart features. It’s a seriously great wearable. If you’re on Android, though, the Galaxy Watch is your best bet.
  • Fossil Gen 5 or Skagen Falster 3: The Fossil Gen 5 and Skagen Falster 3 are two of the best Wear OS watches you can buy. They’re not the best smartwatches ever — they can thank Wear OS for that — but we still really enjoyed reviewing these devices. They also seem to be on sale every other week.
  • Garmin Forerunner 245 Music: If you want a smartwatch that prioritizes accurate fitness and health stats, the Garmin Forerunner 245 Music is a good option. It’s one of our favorite fitness watches of all time, thanks to its long feature set and relatively affordable price. It’s not as “smart” as the Galaxy Watch, but it’s likely the better fitness wearable.
  • Samsung Galaxy Watch Active 2: Duh! If you’re not into the Galaxy Watch 3’s high price tag, or its kinda chunky design, the Galaxy Watch Active 2 gets you most of the same features in a slimmer, cheaper package.

These smartwatches are on sale quite often. Be sure to check our best smartwatch deals hub for discounts on today’s popular wearables.

Samsung Galaxy Watch 3 accessories

Top Samsung Galaxy Watch 3 questions and answers

samsung galaxy watch 3 review display watch face 2

Q: What happened to the Samsung Galaxy Watch 2?

A: Good question. Samsung likely chose to go with “Galaxy Watch 3” to keep it more in-line with its other Active line of smartwatches. Launching a “Galaxy Watch 2” after the Galaxy Watch Active 2 has been out for so long might confuse some people.

Q: Does the Samsung Galaxy Watch 3 have MST?

A: Unfortunately, no. Samsung confirmed that the Galaxy Watch 3 does not support MST technology with Samsung Pay — only NFC. It’s a bummer, and we hope Samsung brings back this wonderful feature in a future smartwatch.

Q: What watch straps work with the Samsung Galaxy Watch 3?

A: The 41mm Galaxy Watch 3 is compatible with any traditional 20mm straps, while the 45mm variant works with 22mm straps.

A: TBD! We are waiting for Samsung to publish the full list of compatible networks. Stay tuned for more updates in the next few days.
