2025 UTMB winner Ruth Croft is among the athletes measuring their training and racing efforts with the new Amazfit product.
Amazfit is making big strides in the smart wearable market, and it’s easy to see why. One of its latest products, the T-Rex 3 Pro, recently arrived in Europe and has received rave reviews so far.
With a titanium design, a powerful flashlight and advanced offline maps that enable automatic route planning, the watch has a number of impressive features.
The watch is worn by, among others, recent Ultra-Trail du Mont-Blanc winner Ruth Croft, while other Amazfit ambassadors include Olympic 5,000m and 10,000m medalist Grant Fisher.
Designed mainly for endurance athletes, the Amazfit T-Rex 3 Pro has more than a dozen new features, such as advanced mapping functions, an integrated flashlight, microphone and sapphire glass to protect the screen, while incorporating a stronger material in its construction: grade five titanium alloy.

Whether you’re a road, mountain, ultra, trail or track runner, the Amazfit T-Rex 3 Pro is designed for anything. Its screen is protected by scratch-resistant sapphire glass, and the bezel and buttons are made of grade five titanium, a material that’s more durable than standard alloy yet harder and lighter than stainless steel.

The smart watch can work in temperatures from -30°C to +70°C. Equipped with a two-color LED, it provides visibility in the dark along with an SOS signal.
The product works seamlessly with the impressive Zepp app on your phone. As well as measuring your workouts and races, interactive and detailed free offline maps are among the best features. In this regard, the T-Rex 3 Pro can search for locations and create or create new routes. Just set a direction and enter the distance you want to cover, whether it’s running, walking or cycling.

It’s also impressively accurate because the antenna uses circular polarization, allowing it to receive GPS signals more frequently. In addition, the smartwatch supports dual-band, which minimizes the negative impact of interference caused by strong wind, tall trees or buildings.
If you like to mix your athletics with other sports too, there are 180 options, from indoor rowing and elliptical machines to Hyrox.
