That has changed: Amazfit now lists the T-Rex Ultra 2 on its US product site and provides an official manual. The app-code sighting was an early clue, not confirmation of the rumored upgrades in the original article.
Amazfit lists the watch at $549.99 in the US. Its published specifications include a 1.5-inch AMOLED display, 870 mAh battery, 10 ATM water resistance, and a 26 mm silicone strap. These are manufacturer claims; this article does not report independent testing.
What the app-code sighting showed
Wareable reported on January 15, 2026 that the name “Amazfit T-Rex Ultra 2” appeared in Zepp app version 9.16.2. At that time, Amazfit had not officially acknowledged the device.

Those reports establish that the name appeared in app code. They do not confirm a launch timetable, display technology, satellite features, sensor changes, or other rumored specifications. Amazfit’s current product listing and manual are the relevant sources for the watch’s official details.
