At Amazfit, the T-Rex series stands for the brand’s most robust smartwatches and has received a new flagship today with the Amazfit T-Rex Ultra. As the name suggests, the Ultra offers even more features for extreme athletes. The focus is on a 1.39-inch AMOLED display with a resolution of 454 x 454 pixels and a peak brightness of 1,000 cd/m².

The housing has become even more durable and is now certified for freediving to a depth of 30 meters (EN13319 and ISO 6245). The case is made of polymer alloy, while the bezel, buttons, back and bridge are made of stainless steel. However, this also makes the Amazfit T-Rex Ultra quite massive at 89 grams and a thickness of 13.45 mm.

There’s also a MIL-STD rating for 15 different tests. These include a mud-resistant construction that keeps dirt and sediment out of the watch’s interior. The watch also withstands extreme temperatures from -30 °C to +70 °C. The dual-band GPS receiver can also be used with offline maps and real-time motion updates. The T-Rex Ultra also offers automatic training recognition for up to 25 sports. The integrated biometric BioTracker PPG sensor ensures accurate heart rate and blood oxygen monitoring.

The Amazfit smartwatch builds connections via Bluetooth 5.0 LE and Wi-Fi, while the operating system is Zepp OS 2.0. There’s also the option to download mini apps through the Zepp app, including a GoPro app to pair a action cam.


The T-Rex Ultra features a 500mAh battery that charges via a proprietary magnetic charging dock. The battery life is 20 days with typical use and 9 days with heavy use. The watch also has special endurance modes. These include endurance GPS mode, which can last up to 3 days with activated position data.

The Amazfit T-Rex Ultra is available in Abyss Black and Sahara colors and costs $400 (€372). Details on market availability will be announced shortly.
