Expert opinion
The T-Rex Ultra is Amazfit’s first Ultra-tier adventure watch, built with 316L stainless steel, dual-band GPS, and freediving support to 30 metres. It won a Good Design Award in 2023 and shipped with a 1.39 inch AMOLED display and 20-day typical battery life.
The June 2024 update added contour maps, turn-by-turn directions, Zepp Flow voice commands, and Readiness, moving the watch to Zepp OS 3.5. The display peaks at 1,000 nits, lower than the 3,000-nit panels on later Amazfit watches. The successor, the T-Rex Ultra 2, is larger with a brighter 1.5 inch display and longer battery life.
