Amazfit T-Rex Extremely GPS Smartwatch Assessment


Final spring, when you informed me I’d quickly be excited over a watch named after a theropod, I’d have referred to as you a liar. However a curious factor occurred in June of 2022 when a GPS-enabled fossil confirmed up within the mail. (No, not that type of Fossil.)

I’m speaking concerning the Amazfit T-Rex 2, one of the crucial versatile and succesful journey watches within the sub-$400 panorama. And the most recent of those is the Amazfit T-Rex Extremely ($399).

 “With options like a chrome steel and mud-resistant design, 30 m freediving assist, dual-band GPS and route navigation, ultra-low temperature operation, and 20-day battery life, this smartwatch is the last word device for out of doors lovers,” the model claims.

You had me at “mud-resistant,” dino fam. Be part of me as I cowl every week’s price of testing with this metal-clad GPS smartwatch provided (full disclosure) by Amazfit.  

Briefly: The Amazfit T-Rex Extremely ($399) is a worthy improve to one in all my favourite smartwatches of final summer season. Whereas the change to a 316L metal case provides weight to the general package deal, the sensation of stability and high quality is an ideal match for the watch’s aesthetic. Battery life dips barely, however the addition of offline map downloads and new adventure-focused exercise modes goes a good distance towards making the Extremely precisely that.

T-Rex Extremely vs. T-Rex 2

Let’s begin with what hasn’t modified. Each fashions use the identical 454 x 454-pixel AMOLED display screen, protecting 1.39 inches with its “glass materials” crystal. GPS employs a “dual-band and 6 satellite tv for pc positioning system,” and the optical sensor is identical BioTracker 3.0 PPG.

However Amazfit added a number of excessive sports activities modes to the Extremely’s quiver, together with free diving and sky diving. For extra earthbound adventures, the corporate upgraded the mud resistance of its {hardware}, together with the change to a 316L chrome steel case.

There’s additionally a brand new slate of offline performance. Per the advertising and marketing copy, “With the Amazfit T-Rex Extremely, now you can seek for and obtain an identical Offline Map of your deliberate exercise space from the Zepp App and match it along with your imported route for even higher understanding of your environment.”

There’s one other delicate contact right here that deserves to be talked about: Amazfit’s new methodology of attaching the silicone strap (which, by the best way, is sort of snug). The hinged twin lugs are a deal with, permitting the watch to put flat in your desk or bedside desk. That is one thing the T-Rex 2 couldn’t do.

Battery and Weight: It’s Difficult

One other factor the Extremely provides is weight: 89 g with out the strap versus 66.5 g for the T-Rex 2, strap included.

However truthfully, I’m counting this as a constructive. The metallic case feels far more substantial, and the distinction is straight away recognizable. Notice that it says “with” stainless, not “all stainless.” The body consists of “polymer alloy,” however for probably the most half, metal is the medium of selection.

Nonetheless, there may be one drop price mentioning, and that’s the battery life. Whereas the earlier mannequin was rated for twenty-four days of typical utilization (or 10 days for heavy use; 45 with Battery Saver), the Extremely’s ranking dips to twenty days of typical (with 9 of heavy use; 25 days in Battery Saver).

It is a bit perplexing, because the Extremely really surpasses the T-Rex 2’s battery life when utilizing sure GPS settings. As an illustration, Accuracy Mode on the brand new mannequin raises the Extremely’s estimated life to twenty-eight hours versus 26 hours for the T-Rex 2.

There’s additionally a brand new “Endurance GPS Mode” with a projected lifespan of 80 hours, which effectively exceeds the 58-hour mark of its predecessor. It seems that, by placing its batteries within the go-hard journey basket, Amazfit has misplaced only a hair of its day-to-day endurance.

Working System: Zepp 2.0

A be aware concerning the OS — whereas Zepp will not be fairly as intuitive as its bigger-name competitors, it’s a strong, purposeful platform. The Extremely upgrades to Zepp OS 2.0, which options delicate enhancements from the unique.

It’s a bit onerous to clarify, however all the pieces feels smoother, brighter, and extra polished. Even water splashes (which used to require that I lock the controls within the bathe) appear to be much less of an issue with out lowering the tactile response of the display screen.

Testing the Huge Claims

Amazfit locations a excessive emphasis on the cold-blooded nature of the T-Rex Extremely. “Outlast the Ice Age,” the web site reads, with a “specifically designed circuitry system and battery” good for temperatures as chilly as -40 levels Celcius.

As such, an in a single day keep within the freezing rain didn’t section the watch one bit. Nor did the scalding sizzling bathtub it was thrust into in the course of the morning to check its resilience to thermal shocks.

Shifting onto a distinct type of shock, my impression testing started with a toss from a second-story window. However the snowbank it landed in appeared too tender to attract any actual conclusions. Subsequent got here the pavement, with a repeated sequence of lobs and retrievals. Then, I seen a pleasant patch of mud close to the facet of the highway.

Yeah, that’s the stuff. Amazfit boasts concerning the Extremely’s “Mud-resistant {Hardware},” and the watch lived as much as the billing. However who is aware of what squirrels or canines might need finished with stated mud?

There was just one approach to make certain the watch received clear — into the washer it went. After a full wash, rinse, and spin, the Extremely confirmed zero in poor health results.

Conclusion: Amazfit T-Rex Extremely GPS Good Watch Assessment

You would possibly discover an absence of destructive suggestions right here. A small discount in battery life, a number of grams of extra weight and, effectively, that’s roughly it. As a smart-watch skeptic, I anticipated to search out extra to complain about.

If the T-Rex 2 made me a believer, the Extremely has made me an fanatic. I’m typically eager to get again to my easy analog timepieces as soon as the assessment of a wrist-computer is full.

However on this case, I genuinely look ahead to strapping on this Amazfit when it’s time to hit the health club, the highway, or the path. From its rugged functionality and interface to its snug, well-considered design, the T-Rex Extremely, you would possibly say, earns its bones.
