The new T‑Rex Dual Solar features a dual‑sided solar system: the front AMOLED screen can capture sunlight while worn, and a larger solar panel embedded in the glass‑ceramic rear plate—claimed by Amazfit to have twice the collection area of the front—continues charging the watch when it’s off the wrist.
Powered by a 660 mAh battery, the watch is rated for up to 25 days of typical use and 41 hours in Accuracy GPS mode. Under test conditions of 50,000 lux for three hours a day, the battery life can be extended to roughly 34 days.
The rugged device sports a 1.32‑inch AMOLED display with a peak brightness of 3,000 nits, sapphire crystal protection, a Grade 5 titanium bezel, and 10 ATM water resistance. It also includes built‑in maps, turn‑by‑turn navigation, waypoint tools, ski maps, LiveShare location tracking, and a red‑light flashlight for night use.
Priced at $650, the T‑Rex Dual Solar positions itself against Garmin’s Fenix series, which traditionally forces a trade‑off between solar‑enabled MIP displays and brighter AMOLED screens. Amazfit’s offering aims to combine a vivid AMOLED display with solar‑extended battery life without sacrificing durability.
The watch is now available for purchase on Amazfit’s official website and on Amazon. Real‑world testing will reveal whether the dual‑sided solar system can consistently deliver the advertised battery longevity in everyday outdoor adventures.
