Third-party reviews

What we like about Amazfit T-Rex 2

  • Battery is rated at 24 days, and training mode runs for 50 h.
  • Water-resistant to 100 m, enough for swimming.
  • Dual-frequency GPS locks on quickly and stays accurate on bike rides.
  • Operating down to -30 °C suits cold winter walks.
  • Heart rate tracking comes close to a chest strap.
  • Smart alarm wakes you during light sleep, within a 30-minute window.

What we don't like about Amazfit T-Rex 2

  • At 66.5 g and 47.1 mm wide, it is heavy for smaller wrists.
  • No speaker or microphone, so no calls or voice assistant.
  • Maps are limited to a route line and arrows, with no full offline maps.
  • Routes must be imported through the Zepp app, which is fiddly.
  • Charging cables from other brands do not work with it.

Verdict

Someone who swims, hikes and wants a simple watch will find the Amazfit T-Rex 2 easy to live with. The battery is rated at 24 days, and in training mode it runs for 50 h. The watch is water-resistant to 100 m, enough for swimming, and it has dual-frequency GPS for accurate routes. The minimum operating temperature of -30 °C makes it useful on cold winter walks. It counts 150 exercise modes and tracks sleep and blood oxygen. The downsides are size and extras: at 66.5 g and 47.1 mm wide it is heavy for smaller wrists, and there is no speaker or microphone. Maps are limited to a route line and arrows, not full offline maps. It fits someone who wants a tough, long-lasting watch for training and does not need voice or calls.
