Amazfit’s most expensive watch until the $649.99 T-Rex Dual Solar arrived, and the spec sheet explains why: an 870mAh cell good for 30 days, 50 hours of full-accuracy dual-band GPS, and a 3,000-nit AMOLED behind sapphire. The 51mm case swaps steel for grade-5 titanium on the bezel, buttons, and back, and stays operable at −30°C. Dive certification runs to 45m under both EN13319 and ISO 6425, alongside a flashlight, emergency SOS, offline maps with route import, and 40,000 golf courses. What it still does not have is an ECG or contactless pay in the US, and at $549 it is asking Fenix money for software that is several years younger.
Strengths
- 50 hours of full-accuracy dual-band GPS, 30 days typical
