Amazfit T-Rex Ultra 2: A Deep Dive into the Rugged Smartwatch

Amazfit has launched the T-Rex Ultra 2, a high-specification fitness watch positioned to compete with established players like Garmin and Apple. Building on the foundation of the T-Rex 3 Pro, the Ultra 2 offers enhanced durability, extended battery life, and a suite of features tailored for outdoor adventures.

Dimensions and Build Quality

The Amazfit T-Rex Ultra 2 boasts a larger case size than its predecessors, measuring 51mm in diameter, making it suitable for larger wrists. It maintains a weight of 89 grams (including the strap) thanks to the use of a titanium frame, titanium side covers for the sensors, and titanium buttons. The display protection has been upgraded to sapphire crystal, offering improved scratch resistance compared to the tempered glass used in previous models. The strap width has also increased to 26mm, utilizing a quick-release mechanism compatible with Garmin straps.

Display and Battery Life

The watch features a 1.5-inch AMOLED display with a resolution of 480×480 pixels, an increase from the 1.39-inch, 454×454 display of earlier models. Brightness has been significantly boosted, reaching a maximum of 2000 nits with a peak of 3000 nits, ensuring visibility in bright sunlight. A glove mode is included for reliable operation in various conditions.

Battery life is a key strength of the T-Rex Ultra 2. The increased battery capacity of 870 mAh (up from 500 mAh) translates to up to 28 hours of activity tracking with dual GPS and always-on display enabled. With normal use and notifications activated, Amazfit estimates up to 30 days of battery life.

Durability and Water Resistance

The T-Rex Ultra 2 is built to withstand harsh environments. It offers water resistance up to 10 ATM, is capable of diving to depths of 40 meters, and can operate in temperatures as low as -30°C. It can also be charged in temperatures as low as -10°C.

Flashlight and Navigation

The watch incorporates a built-in flashlight, brighter than the version found on the T-Rex 3 Pro, with adjustable white light brightness and a green light option. The green light is intended for compatibility with night vision devices.

The T-Rex Ultra 2 includes pre-installed world maps and allows for the download of detailed maps for specific regions and ski resorts, based on OpenStreetMap data. Offline route planning and navigation have been improved, with automatic route recalculation, checkpoint reminders, and points of interest information.

Software and Features

The Zepp OS operating system continues to evolve, with enhancements to map functionality and navigation. New features include a ClimbPro-like mode for displaying uphill climb information and BioCharge energy monitoring. The watch also supports NFC for payments, and includes a microphone and speaker for making calls from a connected phone and interacting with an onboard AI assistant.
