The topmost layer of the GTR 2's construction is what really sets it apart from the original GTR. And, as always, saltwater is a definite no-go. Naturally, you can expect some issues with the microphone and speaker shortly after exposure. The GTR 2 is water-resistant enough to track your swimming (in fresh water). The latter is really nothing more than a gimmick, though, since it is a very tiny speaker. You can also get actual sound alerts for things like notifications or calls via the speaker and even play music through it. For the time being, these just offer simple voice navigation for the watch itself, but Amazfit has promised Amazon Alexa support in an upcoming update. The other purpose of this hardware is voice commands. The integration of a loudspeaker a mic has allowed the watch to be used for taking calls via Bluetooth. The bigger one on the left is the speaker. The holes on either side of the device are there to accommodate the new speaker and microphone. Looking at the backs of the original GTR and the new one side by side quickly reveals two other major hardware additions to the second generation.
AMAZFIT GTR2 BAND SOFTWARE
Though the latter might just be a software improvement rather than a hardware one.
Cutting through some of the marketing talk here, like the trademarked OxygenBeats tech, the new hardware seems to bring blood oxygen measurement (SpO2) to the table, as well as automatic workout detection. The sensor itself is version 2.0 and has an extra visible part compared to the one on the original GTR and the T-Rex. On the plastic back, we find the familiar elevated portion, housing Huami's trademarked PPG BioTracker. Plus, if you really don't like the factory band, it uses a standard 22mm attachment mechanism, making it really easy to pick up a third-party replacement of your choosing. We had no issues with the fit of the GTR 2 from a small female hand to the fairly-beefy male one you can see in the lifestyle photos. Plus, it feels sturdy enough, and we appreciated the plentiful punch-holes and their tight spacing on the other side. Perhaps that's just for the Sport edition. The clasp is a bit on the cheap side and appears to be plastic instead of the metal one w have on the old GTR. Soft enough to be comfortable and elastic enough to instill durability confidence. As far as silicon straps go, it is alright. The "sweat-proof obsidian black silicone strap" on our review unit invokes mixed feelings. The GTR 2 Sports Edition, which is the one we have for review, is made of aluminum alloy and tips the scale at 31.5 grams, while its Classic sibling is crafted out of stainless steel and is slightly heavier at 39 grams.īeyond the main watch body, the two versions also ship with different straps - a sweat-proof silicon one for the Sport Edition and a leather one for the Classic. Both also have the same hardware and the exact same 1.39-inch AMOLED display. The two share the same physical design and proportions. The Amazfit GTR 2 has a Classic edition, as well as a Sport Edition.
