Two variants with different sizes
In addition to the familiar 48mm model, which is largely unchanged from its predecessor, the T-Rex 3 Pro is also available in a more compact 44mm version. At approximately 63 grams including the strap, it's a bit lighter and slimmer. It features a 1,32-inch AMOLED display with 3.000 nits of brightness and a 640 mAh battery, which, according to Amazfit, has a battery life of 19 days.
The larger model, on the other hand, has a 1,5-inch AMOLED, also with up to 3.000 nits of brightness, and a slightly larger 700 mAh battery that should last up to 25 days in standard operation.

More robust housing with new features
Amazfit also goes a step further with the material. While the T-Rex 3 (our review) While the 10s used stainless steel and Gorilla Glass, the Pro version uses titanium and sapphire crystal. Both models are water-resistant to 30 ATM and can withstand temperatures from minus 70 to plus XNUMX degrees Celsius.
New additions include an LED flashlight on the edge of the case, as well as a speaker with a microphone, so that calls can be made via Bluetooth directly on your wrist.

Improved navigation and BioCharge Energy Score
Offline maps are now interactive, searchable, and can automatically calculate routes. Turn-by-turn navigation has also been enhanced. The GPS uses circular polarization and dual-band, which should ensure more stable positioning even in dense vegetation or between tall buildings.
More than 180 sports are now supported, including new programs for HYROX. The BioTracker 6.0 records heart rate, blood oxygen, sleep quality, and heart rate variability. With the BioCharge Energy Score, the smartwatch also provides information on recovery status and daily fitness.
