Amazfit T-Rex 2: resistance and price to spare

The Amazfit T-Rex 2 was announced globally last May and became official for the Brazilian market at the end of June, arriving under the proposal to serve users who usually practice extreme sports and visit extreme scenarios, but who do not want to abandon their technology partner.

But does all this durability and resistance reflect the overall quality of the smartwatch? Here’s what you can see below in our full review!

Amazfit GTR 3 Pro: Best value for money

April 09

construction and design

Sold in a box reminiscent of traditional watches, the T-Rex 2 comes with its manual, certificates, and charging cable with magnetic screws; A group we are used to seeing for this type of product.

In a style reminiscent of Casio’s popular G-Shock watch, made of polymer alloy with a silicone strap with a classic pin buckle, the overall suggestion of the Amazfit watch is resistance.

With military MIL-STD certification, the model is capable of operating in extreme temperatures, from -40 to 70 degrees Celsius, as well as enduring – in tests – 240 hours of exposure to moisture, 96 hours of salt water spray, ice and freezing rain; Plus the ability to indulge in pressure up to 10 atm.

Until he put his durability to the test, The form has already been sent into space upon reaching the stratosphere, being exposed to an average speed of 290 km/h and a temperature below -64°C, and returning to Earth in a fully operational state , thanks to its GPS.

Available in four variants: black with gold, black with silver, green and beige, the new T-Rex comes with a 1.39-inch round AMOLED screen with a pixel density of just over 460 ppi, ensuring great color viewing and high definition of the elements displayed in the interface.

Our only criticism here goes to the proximity between the screen glass and the edge of the case. Because it’s so close, and because the glass doesn’t have any kind of dedicated certification, we were worried about the screen being easily scratched or even broken during some of the more drastic activities.

In any case, the screen has an automatically adjustable brightness and Always On mode, which makes the screen always visible and active, which brings the operation of the smart watch closer to the operation of a normal watch; Something that may sound silly, but this increases the practicality of not having to keep rotating your arm, touching the screen, or pressing a button to tell the time all the time.

but this is not all. Unlike most watches that have passed through our seats, in addition to touch, the entire system can be interacted with through the buttons distributed on the sides of the watch. One button to go up, another button to go down, one to go back and a fourth to select the highlighted item.

This approach, combined with the resistance guaranteed by all of its certifications, can guarantee the most extreme users – the wearable target audience – a great experience even in the most extreme environments; It will ensure perfect mobility even with the watch completely submerged.


And if the durability of the case does not disappoint, we can say the same about the sensors built into the T-Rex 2. In addition to the aforementioned proximity sensor, the watch is also equipped with a dual-band GPS with support for five satellites: GPS, gyroscope, compass, altimeter and barometer; Navigation and location basics.

Equipped with Bluetooth 5.0 and embedded with Amazfit’s proprietary system – Zeep OS, the wearable still supports widgets, which end up expanding its usability, but still doesn’t allow it to be framed in the same section of a smartwatch, of course. reality.

These widgets, which can be accessed through the App Store on Zeep, extend the usefulness of the watch by another centimeter, being very accurate. Forget Spotify, Strava, Google Fit, etc.; Here you will find options such as calculator, water time, dental cleaning, etc.

The only apps out there that communicate with third parties are Notify for Gclock, Notify for Maps, and GoPro. The first two, to interact with the Google Watch and Maps apps, and the third, to control the GoPro.

Unfortunately, the restrictions do not stop there. Contrary to what happens even on cheap watches from the brand, it is not possible to answer calls from your smartphone via T-Rex, only to reject them; The same is true for notifications. Here, it can only be viewed, but the response will remain limited to the smartphone.

However, when making a comparison, we can say that the Amazfit model is an upgraded Mi Band 6, but it is not a smartwatch. And within his suggestion of him, we can say that he does everything relatively well.

Navigation in Zeep OS happens smoothly, without any kind of stuttering and the feature set is quite complete for activity monitoring. It is possible to track your stress levels, heart rate and blood oxygen, monitor your sleep hours and track the levels of your training sessions.

And speaking of training, we have a nice difference here! In addition to the 150 available sports, which include – believe me – even board games, the watch is able to automatically detect dozens of strength exercises, as well as some sports, which show in the application the muscle groups worked during the exercise; surprising thing. A positive point for Amazfit


Still talking about the app, here we have Zepp – the direct successor to Mi Fit; That, despite the change of name and interface that it received thanks to the small confusions that Xiaomi generates with its subsidiaries, it maintains the good qualities of its predecessor, with a simple and intuitive appearance.

Anyway, regardless of the name, with the information collected by the T-Rex 2, Zepp can keep a complete log of user data, keeping a record of the steps taken, the physical activity sessions performed – visualizing the muscle groups working, the rate Heartbeat, stress and oxygen indicators, sleep records, etc.

With the wearable properly connected via Bluetooth, the app also allows you to make more advanced adjustments including taking measurements, setting alarms, making adjustments to monitor sleep and stress, setting goals, and tracking your period, as well as the option to choose from new screen dials.

In addition to the dials available by default through the watch itself, it is possible to select and synchronize a new disk from a partition built into Zepp itself. This one has several options available, with screens divided into categories such as “Classic”, “Training and Health”, “Technology”, “Multiple Information”, “Realism” etc.

Size: Varies by platform


Owner of a 500 mAh battery that can be charged in about two hours, Amazfit promises autonomy of up to 24 days for the T-Rex 2; This is an impressive number in theory. But what about practice?

In our tests, in moderate use, without Always On, with a few training sessions, heart rate tracking, continuous sleep monitoring, and sporadic measurements of oxygen and pressure, the watch was able to stay offline for about 20 days. Integers – The value of it closely matches the Brand Promise.

Therefore, an autonomy that does not exceed expectations, thanks to the Amazfit itself, but it is good if we take into account similar models and even simpler activity monitors.

Is it worth it?

It was announced by Amazfit at the end of last June with a suggested price of R$1,540, considering that the T-Rex 2 is a good option that – given the options on the market – could be something more difficult than damaging the watch by immersion in salt water.

Understand that the device could be great for a very specific audience, those who like to venture out in the middle of trails or climbs, promising resistance hard to see in other options on the market, as well as providing a battery befitting of those. who intends to spend one week away from civilization.

However, taking into account the proposed price, depending on the use, it may be better to buy, for example, the Galaxy Watch 4, which can already be found around 1200 R$. And in adventure time, cover your Samsung watch with one of these tough cases, which can be found for under 200 BRL.

Of course, this will not bring good certifications or autonomy of the T-Rex 2 to the Samsung watch; But nothing is being done, either, that will bring the full suite of South Korean smartwatch features to the Amazfit model.

With all the cards on the table, choosing a T-Rex becomes a matter of specific needs. Do you want to spend a week in the woods, without electricity, and want to have a watch on your wrist that will take a beating? The Amazfit model might be the best option. But if that’s not your case, other – smarter – options might sound better.
