Amazfit T-Rex 2: Design and Build

Amazfit T-Rex 2 comes with a cool and tough design that appeals to people who love rugged smartwatches like me. This watch comes with a big and chunky casing which is made of Polymer Alloy to give it extra durability.

We have the Amber Black variant here but you can also buy it in a limited edition Khaki color. Despite being very durable, it weighs 66.5 grams, comparatively less than other rugged smartwatches that come with metal casings.

The watch uses 22mm straps and you can buy aftermarket straps from various e-commerce sites. However, replacing them is tough because you need a precision screwdriver with a compatible bit to remove them.

You get a classic pin buckle mechanism to fasten the watch on your wrist. Overall, the straps are very comfortable on the skin and also very breathable so you don’t sweat much during your workout sessions.

In terms of durability, the Amazfit T-Rex 2 comes with a MIL-STD-810G rating which means it went through some of the toughest tests. The watch can work in temperatures as high as 158°F and as low as -40°F which makes it the best companion for trekking.

It comes with a 10 ATM water resistance rating which makes it an ideal companion for casual swimming. To test the watch’s temperature resistance, I froze my T-Rex 2 in the refrigerator and the watch kept on working even with a substantial amount of ice formed on it.

The watch has four buttons on the case to navigate through the complete user interface. On the right are the Select and Back buttons and on the left are the Up and Down buttons.

You can navigate through pages using the up/down buttons, confirm using the select button and go back using the back button. I loved these buttons since they can help you navigate through watch features even when wearing gloves.

Overall, I am very much satisfied with every design aspect of the Amazfit T-Rex 2. The build quality is top notch and you cannot think of the ways you can torture it and it will still be working fine.

Amazfit T-Rex 2: Display

Amazfit T-Rex 2 comes with a big 1.39 inches AMOLED display which is a big display to show a lot of content on it. It comes with 454×454 resolution and 326 PPI pixel density making it one of the crisp displays you can get on a smartwatch.

This display also gets very bright, with a brightness of 1000 nits, the content is easily readable even under direct sunlight. You can check our detailed brightness shootout here.

The display also got a really smooth finish on the cover glass which makes the responsiveness even better. There’s an oleophobic coating on the cover glass to avoid smudges and ensure clear visuals all the time.

Auto-brightness feature is available in the watch and it works flawlessly without adjusting your wrist again and again. And not to forget, there’s also an always-on screen which can be enabled from settings.

Amazfit T-Rex 2: Features and Sensors

Amazfit T-Rex 2 comes with all the smartwatch features that you can expect from a modern smartwatch. It can show you notifications and you can even use quick replies to answer texts and WhatsApp messages.

You can control your music from the watch and you even get an App Store inside the Zepp app to install apps provided by Amazfit. Unfortunately, these are very basic apps and the watch does not support third-party applications yet.

Amazfit Trex 2 Review Sensors

Amazfit T-Rex 2 comes with a lot of sensors on it to measure every part of your health and present you with a deeper look at the data. It comes with a BioTracker 3.0 PPG, a biometric sensor, acceleration sensor, gyroscope, geomagnetic sensor, barometric altimeter, and ambient light sensor.

For positioning, it gets a dual-band GPS and 5 satellite positioning and for connectivity, it comes with Bluetooth 5.0 BLE. You can also use GPS map navigation on the Trex. The GPS locks quickly and works accurately.

The watch comes with 150+ sports modes which you can quickly start from the app as well as from the watch itself. Other than that, you get all the basic features like 24-hour HR monitoring and stress monitoring.

It also comes with some high-end features like auto blood oxygen monitoring, sleep tracking, and complete health monitoring.

Amazfit T-Rex 2: Watch UI

The smartwatch comes with Zepp OS which has one of the most fluid UI you can find on a budget smartwatch. It has a very intuitive user interface. The right swipe will open the notifications and a down swipe will bring down the quick settings. Swiping up will bring up the widgets page, and the left swipe will switch the apps menu.

Pressing the back button on the watch will bring up the app’s menu and the select button works as a quick shortcut to start a workout. The quick settings and the widgets page are very customizable and you can do that from the app or even on the watch. You can even install some extra features from the phone app if you want.

There are a lot of watch faces available on the watch to choose from and you can add even more from the app. You can even customize some watch faces to match the accent colors on the watch. You can set up a custom watch face where you can add any image from your phone gallery as the watch background.

Amazfit T-Rex 2: App Experience

Zepp app shows all the health data right on the first screen when you launch the app. This is exactly what I expect a health-centric smartwatch app to do.

At the top, you’ll see the steps and calories burnt, then sleep data, after that you see your heart rate and then you see rest health data. Tapping on each of them will give you detailed data about the respective category with graphs.

The second tab on the app is for health and this page is not of much use as you can only see a glance of walked steps and other small things. The profile page is where you can do all the customization in your profile and on the watch.

Once you are inside the watch settings, you find tonnes of settings and customization features for the watch. You can also connect the watch with Google Fit.

Amazfit T-Rex 2: Battery & Charging

Amazfit Trex 2 Review Battery

Amazfit T-Rex 2 comes with a 500 mAh battery and the brand claims to give you 24 days of battery backup at typical usage. This claim came out to be true in my testing as I got more than a week of usage with a 50 percent battery.

The watch charges faster with its magnetic pogo pin charger, it tops up from 0 to 100 percent in under 2 hours. The charging speeds are satisfactory considering it’s required only a few times in a month.

Amazfit T-Rex 2: Pros and Cons


  • Military-grade build
  • Bright and crisp display
  • Reliable health sensors
  • Dual GPS
  • Smooth UI
  • Long battery backup


  • A bit chunky
  • No calling feature
  • No Alexa support
  • Weak magnets on the charger

Amazfit T-Rex 2 Review: Final Verdict

Amazfit T-Rex 2 is a perfect smartwatch for the niche audience that loves adventure sports like trekking, dirt biking, and more. It is also an ideal companion for tracking in all kinds of weather conditions. Plus, it is priced quite right when compared to some other rugged watches on the market. However, if you’re in for other productivity features like calling or voice assistant, you may have to look somewhere else.
