Amazfit Falcon vs T-Rex 2 vs GTR 4: comparison feature

Zepp Health has been busying itself dishing out new watches in the Amazfit series. The latest to drop today is Amazfit Falcon. This is the most expensive watch in the range, built with premium materials for the outdoorsy types.

Its most direct comparison at the moment is the Amazfit T-Rex 2. Both are very similar in terms of their target audience and things they can do. Another great choice is the GTR 4. You can check out our hands-on review for that one. The device comes with some functionality that cannot be found on these outdoorsy watches.

Amazfit Falcon is only available on the Zepp Health website currently. T-Rex 2 (check price on Amazon) and GTR 4 (check price on Amazon) can also be picked up at other retail outlets.

Not sure which one is right for you? Read on to find out how their specs compare.


Amazfit Falcon vs T-Rex 2 vs GTR 4: Design and hardware

Starting off with the two more similar devices, Amazfit Falcon is a fancier version of the T-Rex 2. Both have the same general, rugged design featuring a circular body and four physical buttons on the sides.

The design differences between them primarily come down to build material. Amazfit Falcon is Zepp Health’s first “premium multi-sports watch”. It comes with a titanium body and Sapphire crystal protected glass. T-Rex 2, on the other hand, comes with a cheaper high-strength polymer case and Gorilla Glass 3 protection.

Mind you, both of these devices are built to take quite a beating and are protected against drops, shocks and all kids of weather elements. In fact they have 15 Military grade certifications. Some examples are the ability to endure extreme cold (-40C) and extreme hot environments (+70C). Whether you are in the Sahara desert or exploring Alaska, either watch will be perfectly fine.

As far as dimensions, Falcon is a bit larger but thinner. Its exact dimensions come in at 49.45 x 47.2 x 12.95mm, while the dimensions of T-Rex 2 come in at 47.1 x 47.1 x 13.5mm. Not a huge difference but it would be difficult for someone with a small wrist to get away with wearing one of these two devices. Having said that, they are fairly lightweight. Both measure around 60 grams which is not too bad.

Moving on to the display and this is where it gets a bit confusing. Despite the larger dimensions, Falcon actually has a smaller display. Measuring 1.28 inches in diameter it is a bit sharper, though, than the 1.39 inch display of T-Rex 2. Zepp Health says the display on Flacon has brightness up to 1000 nits.

Another improvement worth mentioning is water resistance. Falcon has a 20 ATM rating while T-Rex 2 has a 10 ATM rating. Either of these will suffice for most people. Apart from perhaps deep see divers.

In addition to various strap choices, there are a few colour options available for T-Rex 2. This includes Astro Black, Astro Gold, Wild Green, Desert Khaki and Classic Black. At the moment, Falcon is only available in a Titanium (Supersonic Black) version.

As far as GTR 4, this is an entirely different animal. We would consider it more of a fitness or sports watch. Its build is Aluminium alloy coupled with a high-gloss sprayed PC bottom shell. This makes for a very lightweight (34 grams) build. The dimensions are a bit smaller as well, coming in at 46 x 46 x 10.6mm. So this is more of a unisex device.

Of course, you don’t get the long list of military certifications. But you do get a large 1.43 inch display with an excellent pixel resolution. The water-resistance is quite decent, too, at 5 ATM.

The final design difference worth mentioning is the number of physical buttons. You get half as many on GTR 4, so only 2. You can use these in combination with the touch-screen to control the device.


Under the hood

A few significant differences can be found under the hood.

For starters, of the three only GTR 4 has the latest generation BioTracker 4 PPG biological tracking optical sensor. This is an important benefit. In our testing it showed excellent accuracy at capturing heart rate readings, both at rest and during exercise. The other functionality that comes as part of this is the ability to capture SpO2 measurements around the clock.

Falcon and T-Rex 2 have the previous generation optical sensor. Which means they only capture blood oxygen readings on demand and don’t have the same accuracy as GTR 4.

Beyond that the duo offers a geomagnetic sensor, barometric altimeter and compass. This combination of sensors allows for most things you’d expect from an outdoorsy sports watch. GTR 4 misses out on the compass.

Satellite connectivity is also important for an outdoorsy or fitness watch. None of these devices dissapoint. All come with dual-band positioning systems. In the case of Falcon and GTR 4, with support for 6 satellite positioning. In the case of T-Rex 2 with support for 5 satellite positioning.

Battery life

Despite packing a lot of tech under the hood, all of these watches are quite decent when it comes to battery life. This is because they run on Zepp Health’s lightweight proprietary system. You don’t get the full smartwatch functionality that you would get with wearOS or watchOS, but you do get all the fitness functionality.

In terms of numbers, Falcon can keep going for two weeks between charges with normal use thanks to a 500mAh battery. T-Rex 2 has the exact same battery and can keep going for up to 24 days in normal mode. GTR 4 is no slouch, either. Its 475mAh battery is good for 14 days with normal use.

Amazfit Falcon vs T-Rex 2 vs GTR 4: Features

The Amazfit T-Rex 2 is a great outdoorsy watch, particularly when you take its price into consideration. It offers a much less costly alternative to the Garmin Fenix range. Falcon seems to be a revamped T-Rex 2 as evidenced by the same generation heart rate sensor.

However, the device does offer a few extras in addition to the more premium build. There’s its ability to connect to external devices via Bluetooth. This allows you to strap on a heart rate chest strap and take its readings instead of the wrist based figures. Heart rate chest straps are still the way to go if you are serious about tracking your runs and bike rides with great accuracy.

GTR 4 also has this ability in addition to a Gen 4 heart rate sensor which has shown excellent accuracy. It is a nice improvement over devices that pack the previous generation tech.

All three of these watches come with the same general Zepp Health fitness and health smarts. GTR 4 goes a bit further in that it can track blood oxygen not just on demand, but also around the clock. The rest is pretty much the same and this includes the ability to track over 150 different sports, 8 of which automatically – without you having to press a button.

The Zepp Health app has recently benefitted from an update. This makes it much more user friendly and attractive to look at.

There are also some advanced performance metrics sprinkled in. This includes VO2Max, Training Load and Recovery info. We are big fans of these types of metrics and were hoping to see more of them on Amazfit watches.

Zepp Health listened and Falcon comes with something called an AI-powered Zepp Coach. This is their self-developed algorithm which offers customized training guidance. Workout recommendations depend on your current fitness level, training history, fatique and more. We’re not sure if this will come to other Amazfit watches via a firmware update. For now Falcon is the only watch with this feature.

As they are outdoors watches, Falcon and T-Rex 2 also pack a few mapping features. This includes direct-return navigation, real-time navigation and a route-import function. All useful, in addition to the dual-band sattelite connectivity, if you find yourself exploring unfamiliar territory.

Amazfit Falcon vs T-Rex 2 vs GTR 4: Verdict

The T-Rex range offers a great set of features and rugged build. The second generation in this line sells for only $230 – quite a price discount as compared to outdoorsy watches from other brands.

Amazfit Falcon comes in at more than twice this price. This is due to its Titanium body and Sapphire crystal protected glass. The features remain largely the same, with upgrades mostly consisting of better water resistance, the ability to connect to external devices and the AI Powered Zepp Coach.

Does this really justify such a large price difference? We’re not so sure. But if you are in the market for a premium built multi-sports watch, Falcon might peak your interest.

With its smaller body, Amazfit GTR 4 is more of a unisex device. Go for that one if you’re after a fitness or sports watch and are not too bothered about mapping features. Packing Huami’s latest generation sensor and retailing for only $140, it offers great value for money.

Amazfit Falcon is only available on the Zepp Health website currently. T-Rex 2 (check price on Amazon) and GTR 4 (check price on Amazon) can also be picked up at other retail outlets.

  • I’ve had Amazfit watches since the onset of watches. Everything I always wanted in a smart watch is in GTR 4 . Some say it does to much. I say it does everything I want, the hard part is figuring out all the settings. Once I’ve done that ( it took quite a while ) it’s just what I wanted and needed.
    I really like it. I have had Apple, Huambo and this is the best.
    Apple wants you to do ONLY what they LET you do. Sleep function, is up to the watch NOT UP TO YOU.
