Amazfit GTR 3 Pro vs. GTR 3 vs. GTS 3: Key differences compared
Updated: We compare the third-generation Amazfit smartwatches
Zepp Health has added three new additions to its smartwatch range—Amazfit GTR 3 Pro, along with GTR 3 and GTS 3.
They aim to offer the same features you’ll find on Apple Watch SE or Samsung Galaxy Watch 5. If you're ready to pick one up, you can check out Amazfit GTR 3 Pro on Amazon.
The Amazfit range is already busy enough, so this trio only adds to that dilemma of choosing which smartwatch is right for you.

Design compared
Amazfit GTS 3 and GTR 3
We’ll start with GTR 3 Pro, with its 46mm watch case body made from an aluminum alloy, available in brown leather or black. As a package, it weighs 32g.
GTR 3, like Pro, is a round aluminum alloy watch, but it measures slightly smaller at 45.8mm, available in gray and black. You’re also getting a watch that weighs 32g. Like Pro, it uses 22mm straps that are removable.
GTS 3 is the option to go for if you want a square smartwatch. It features a smaller 42.4mm aluminum alloy case matched up with 20mm interchangeable straps that come in three different colors and weigh the lightest at 24.4g. It has just a single button compared to the two you get on GTR 3 and GTR 3 Pro.
Amazfit GTS 3
In the screen department, GTR 3 Pro packs a 1.45-inch, 480 x 480 AMOLED touchscreen display offering the highest screen resolution of the three.
GTR 3 hosts a 1.39-inch, 454 x 454 AMOLED display, and GTS 3 comes with a 1.75-inch 390 x 450 screen.
There’s no separating the three on the water resistance front, with all offering a 5ATM rating, making them safe to swim in water up to 50 meters deep.
If you are all about having the best screen, GTR 3 Pro will get you that. If you care about color options, then GTS 3 offers the most looks. It’s also the lightest.
Smartwatch features
Amazfit GTR 3 Pro
The word Pro does indicate that you might well be getting a few software extras with GTR 3 Pro over the cheaper GTR 3 and GTS 3. Crucially, all models work with Android and iOS devices.
We’ll start with Pro, which runs on the new Zepp OS, bringing new UI animations, an app storefront that supports third-party apps, and access for developers to create watch faces.
Core smartwatch features include notifications that support weather forecasts, music controls, and a built-in music player. Though the latter doesn’t work with third-party services currently.
You can also use it to make calls when paired with your phone over Bluetooth, and it can be used as a smartphone camera remote. There’s also access to Amazon Alexa and Zepp’s offline voice assistant for better hands-free control of core watch features.
Flipping it over to GTR 3 and GTS 3, they largely match Pro for smartwatch features. They also run on that new Zepp OS, bringing all the same extras. It has those two smart assistants and will let you control music playback on your phone.
What they seem to miss out on is the added Wi-Fi connectivity and the ability to make calls over Bluetooth, which is tied to the lack of an onboard speaker.
That also means the non-Pro models miss out on a built-in music player, too. So that’s some big features missing, though it will entirely depend on how much you value making calls and piling your music onto a watch to leave your phone behind for a run.
Health and fitness tracking
Amazfit GTS 3
While Zepp has certainly been ramping up the smartwatch features on its watch to better compete with other full-fat smartwatches, it’s always been well stocked when it comes to tracking things like exercise or keeping tabs on your health without suggesting it’s going to offer serious medical insights.
On the sensor front, these three are evenly matched. You’re getting the latest BioTracker 3.0 optical sensor, which delivers heart rate, stress, and blood oxygen level monitoring.
You’re getting accelerometer and gyroscope motion sensors across the board to track movement and the ability to measure elevation with all three. All models offer the same satellite positioning support, covering the five key satellite systems to make sure your outdoor exercise tracking is nice and accurate.
Amazfit GTR 3
With GTR 3 Pro, you get a temperature sensor, which isn’t available on GTR 3 and GTS 3. Though based on our experience, it wasn’t hugely reliable.
It also has the new one-tap measurement feature to get readings for heart rate, breathing rate, blood oxygen, and stress level in just 45 seconds. That’s also available on GTS 3 and GTR 3, too.
When you’re tracking your fitness, all three watches support the same 150+ sports modes, including running, cycling, swimming, climbing, hiking, and indoor workouts like rowing and the elliptical.
You’re getting automatic exercise recognition for eight of those 150 sports modes. You can also view the new PeakBeats insights on all watches, letting you see data like training load, VO2 Max, and exercise recovery time.
They’ll all work as 24/7 activity trackers to count steps and monitor sleep and naps, breaking down sleep stages, sleep-breathing quality, and basics like duration. Zepp’s PAI Health assessment scores are also available across the devices, too.
If you want to fire your data over to other apps, all three watches support data sync with Strava, Google Fit, and Relive apps.
So what you’re gaining here, going Pro over the non-Pro watches, is the temperature sensor, which we didn’t find particularly useful in its current state. Other than that, you’re getting most of the same features.
Battery life
Previous Amazfit GTR and GTS watches have promised big battery life, but getting that big battery life entirely depends on what features you have in regular use.
With GTR 3 Pro, Zepp says the 450mAh capacity battery can get you up to 12 days in typical use, up to 30 days in battery saver mode, up to six days in heavy usage, and 35 hours of GPS battery life.
GTR 3 also has a 450mAh capacity battery that should get you up to 21 days in typical use, up to 35 days in battery-saver mode, up to 10 days in heavy usage, and the same 35 hours of GPS battery life.
GTS 3 packs the smallest capacity battery, with its 250mAh one delivering up to 12 days in typical use, up to 20 days in battery-saver mode, up to six days in heavy usage, and 20 hours of GPS battery life.
So GTR 3 will, in theory, get you the best battery numbers across the board and match Pro for GPS battery performance too. As we said, it depends on what features are turned on, like using them with the screen set to always-on, enabling continuous heart rate monitoring, and turning on richer sleep features, which can noticeably dent the battery life.
There are no quick charging features on any of these watches, so you can expect them to spend around 2–2.5 hours on the charger if they’re entirely flat and you want to get back up to 100%.
Which is best for you
We’ve compared designs, specs, and all the key software ins and outs, so with your money on the line, where should you be spending it? Here’s our take:
Buy Amazfit GTR 3 Pro… if you want the best smartwatch features that the Amazfit watches currently have to offer, including that built-in speaker and music player. You can find excellent deals on Amazfit GTR 3 Pro over on Amazon.
Buy the Amazfit GTR 3… if you also want a round smartwatch with similar stature and look to Pro, and can live without making calls over Bluetooth and that added Wi-Fi connectivity.
Buy the Amazfit GTS 3… if you want a smaller-fitting smartwatch that largely matches Pro and GTR 3 for features across the board and you’re not fussed about having hours of GPS battery life.
