Amazfit T-Rex 3 Onyx

The Amazfit T-Rex 3 Onyx is built like a tank but smart as hell. With a 1.5″ AMOLED display that hits 2,000 nits of peak brightness, it stays readable in the brightest sun or deepest snow. The rugged 316L stainless steel bezel and polymer body shrug off heat, cold, drops, and deep water — it's even certified for freediving up to 45 m.

You’ll get up to 27 days of battery on a single charge, plus GPS that keeps going for up to 180 hours in max mode. Whether you’re trail running, open-water swimming, or navigating offline maps with dual-band GPS, the T-Rex 3 keeps up. And with 170+ sport modes, AI voice control, and a full suite of pro-level health sensors, it’s got the brains to match the brawn.

Adventure-ready, wrist-friendly, and seriously hard to beat.
