The new Amazfit T-Rex 3 Pro smartwatch is on display at IFA 2025 right now in Berlin. The ultra-rugged smartwatch is designed for trailrunners, endurance athletes, and outdoor adventurers.
As the newest member of the T-Rex 3 family, the T-Rex 3 Pro builds on its predecessor with upgraded materials, enhanced mapping, integrated flashlight, built-in speaker and mic, a sapphire glass screen, and more.
First showcased under embargo during the UTMB race week in Chamonix in August, the T-Rex 3 Pro has a scratch-resistant sapphire glass screen and a bezel and buttons made from Grade 5 titanium alloy, a material harder than stainless steel and more durable than standard titanium.
Available in 48 mm and 44 mm case sizes, both are engineered for durability in any environment: the watch can operate in temperatures as low as -30°C. Equipped with a dual-colour LED flashlight, the watch provides visibility in low-light conditions, including a boost mode for added brightness, red light for low-interference visibility, SOS flash, and safety alerts.
The AMOLED display comes in a 1.5″ (48 mm case) and 1.32″ (44 mm case) size and delivers up to 3,000 nits peak brightness for optimal visibility, even in harsh sunlight. A built-in speaker and microphone enable Bluetooth calling and hands-free communication via Zepp Flow for connection without pulling out a phone. You get up to 25 days of battery life on the 48 mm model and 17 days on the 44 mm.
There’s dual-band GPS and support for six satellite systems to ensure precise location tracking even in challenging terrain. Offline maps feature turn-by-turn directions, smart rerouting, route creation, and points of interest search. Ski maps provide resort data, slope colour codes, and lift locations.
The watch comes with over 180 sport modes, include trail running, recreational scuba diving, strength training with auto rep detection, and official HYROX training and race modes. The exclusive BioCharge energy monitoring system provides a dynamic score based on workouts, recovery, and stress.
T-Rex 3 Pro integrates seamlessly with performance tools like Helio Strap and Helio Ring, connecting to the Zepp App where you can view health, fitness, and sleep data in one place, without the need for a subscription. It’s compatible with both Android and iOS with new third-party integrations coming soon.
The Amazfit T-Rex 3 Pro is available in the U.S. for US$399 and comes in Tactical Black. A Black Gold version of the 48mm model is coming September 25 and Gold and Gray and Black Gold 44mm options in Q4.
