The new & improved Amazfit T-Rex Pro is even more rugged

Huami has announced today the all new Amazfit T-Rex Pro. The adventurers watch is an enhanced version of the original Amazfit T-Rex.

The first generation timepiece was unveiled at CES 2020 and made available for purchase in the US about a year ago. This is a device that is built to last. It comes with US Military Standard 810g (MIL-STD-810G) Certification.

As far as specs, there’s everything you’d expect from an outdoorsy sports watch. The standard gamut of fitness trackers (PPG Optical HRM sensor, 3-axis acceleration, Geomagnetic, Ambient Light), built-in GPS/GLONASS and water-resistance are all there. This is all coupled with nearly three weeks of battery life (20 hours with GPS enabled).

The AMOLED display of the first generation measures 1.3-inches and sits on top of a high-strength polymer 47.7 x 47.7 x 13.5 mm case. Despite all this the thing weighs just 58 grams.

Huami (or Zepp as its now called internationally) is pretty good at churning out Amazfit-branded devices on a regular basis. Some might say a bit too good as it’s becoming increasingly difficult to keep track of all the different iterations!

We knew the Amazfit T-Rex Pro was coming due to the January FCC database registration. This new version looks exactly the same on the outside as the original. But the company says, the device is even tougher this time around having passed 15 military-grade tests. That is 3 more endurance tests than its predecessor in case you were wondering.

Other improvements include 10 ATM water-resistance rating instead of 5 ATM, the newer BioTracker 2 PPG sensor that includes blood oxygen tracking, four global navigation satellite systems (GPS, GLONASS, BeiDou, Galileo) instead of two, a barometric altimeter and more sports modes.

Interestingly, Firstbeat metrics make an appearance on the device. They include VO2Max, Training Load and recovery info. We are big fans of these types of metrics and are hoping to see more of them on Amazfit watches.

Something called ExerSense is also new. It automatically detects and tracks eight sports modes in case you forget to switch them on yourself.

Despite the bump in specs, the battery life is 18 days so not much changed. But with GPS switched on it has been improved to 40 hours. That’s pretty good and what you want from an outdoors watch.

The angular, rugged look remains the same. The main difference design-wise are the Meteorite Black, Desert Grey and Steel Blue colour options. The non-pro version comes in Rock Black, Army Green, Gun Grey, Came Green and Khaki. The outer bezel now has a metal-spray giving it a slightly more premium appearance.

Here are the most important specs.

All in all, this is a nice iterative upgrade over the original device. If you are into adventurous activities, it is certainly worth considering.

In the US you can pick up Amazfit T-Rex Pro at a reasonable $179.99. The watch is up for sale at from today. It can also be picked up at Amazon (check price).

  • When will T-Rex get the Arabic update … because I’m thinking of ditching it in favor of Huawei

  • Does the Pro have track back feature? The previous Trex did not!

  • I didn’t see if this watch support VO2Max, but I’m sure that it’s kot capable to attach a Bluetooth external chest strap, this is a big mistake.

    • Yea It can’t connect to Bluetooth Chest Band, this issue lead to many runners and consumers to avoid this watch….
