Our take on the Amazfit T-REX 3 Smartwatch

The Amazfit T-Rex 3 is a rugged GPS sports watch built for outdoor training and multi-day adventures. It stands out with a large 1.5-inch AMOLED display, a 700 mAh battery rated for up to 27 days in smartwatch mode, and 10 ATM water resistance with MIL-STD-810H toughness. Dual-band GPS and a wide spread of workout modes make it a strong alternative to pricier Garmin and Coros watches, though its app and smart features are simpler. It suits hikers, runners and gym users who want long battery life and durability over polished software.

Questions and answers

Is the T-Rex 3 good for hiking?
Yes. It has dual-band GPS, 10 ATM water resistance, MIL-STD-810H toughness and long battery life, which suit multi-day hikes.
How long does the battery last?
Amazfit rates it up to 27 days in smartwatch mode. Heavy GPS use and always-on display cut that to days rather than weeks.
Can I swim with it?

Does it work with iPhone and Android?
Yes. It pairs with both through the Zepp app, though some features are more limited on iOS.
How does it compare with a Garmin?
It offers a bigger screen, longer battery and rugged build for less, but Garmin watches have more polished software, mapping and training analysis.
What is in the box?
The watch, a magnetic charging cable and documentation. A spare strap is not always included.
