Amazfit T-Rex smartwatch guide for PC

Amazfit T-Rex Review
A tough fitness watch that can take a beating
THE BOTTOM LINE
The Amazfit T-Rex is a rugged fitness and sleep tracker with a color touch screen and long battery life.
Most fitness trackers are built to handle some sweat, but they aren't necessarily designed to withstand a real beating. The $139.99 Amazfit T-Rex, on the other hand, has military-grade certifications, ensuring you can use it in some pretty extreme conditions. Amazfit calls it a smartwatch, but while it offers smartphone app notifications and basic music controls, it lacks features like mobile payments and downloadable apps. Equipped with GPS and an optical heart rate sensor, it can track your distance and route, and offers continuous and manual heart rate measurements, making it more of a fitness tracker in our book, and from that angle it's a solid option for the price.
Tom's Guide Verdict
The rugged Amazfit T-Rex is an outdoor GPS sports watch with impressive battery life and costs less than $150. But its bulky design and limited smarts might not be for everyone.
Huami has made its name on low-cost wearables like the Amazfit Bip, one of the best smartwatches we’ve tested. Now, with the ultra-rugged Amazfit T-Rex, the company has turned its attention to GPS sports watches.

With a large display, on-board GPS, built-in compass and enough durability certifications to survive Jurassic Park, the Amazfit T-Rex looks to challenge Garmin, the megalodon in the room.

Like other devices on our best sports watch page, the T-Rex offers an impressive battery life, variety of sports modes and sleep tracking – all wrapped in its impenetrable shell. But as I discovered during my Amazfit T-Rex review, there were a few compromises made to get to its low price of $140.
TechRadar Verdict
The Amazfit T-Rex 2 is a powerful, chunky beast which looks and feels impressively rugged. It’s a great outdoors watch, but a few small accuracy issues and some less intuitive on-the-fly controls prevent it from being a budget Garmin-killer.
Last spring, if you told me I’d soon be excited over a watch named after a theropod, I’d have called you a liar. But a curious thing happened in June of 2022 when a GPS-enabled fossil showed up in the mail. (No, not that kind of Fossil.)

I’m talking about the Amazfit T-Rex 2, one of the most versatile and capable adventure watches in the sub-$400 landscape. And the newest of these is the Amazfit T-Rex Ultra ($399).

“With features like a stainless steel and mud-resistant design, 30 m freediving support, dual-band GPS and route navigation, ultra-low temperature operation, and 20-day battery life, this smartwatch is the ultimate tool for outdoor enthusiasts,” the brand claims.

You had me at “mud-resistant,” dino fam. Join me as I cover a week’s worth of testing with this metal-clad GPS smartwatch supplied (full disclosure) by Amazfit.

In short: The Amazfit T-Rex Ultra ($399) is a worthy upgrade to one of my favorite smartwatches of last summer. While the switch to a 316L steel case adds weight to the overall package, the feeling of stability and quality is a perfect match for the watch’s aesthetic. Battery life dips slightly, but the addition of offline map downloads and new adventure-focused workout modes goes a long way toward making the Ultra exactly that.
