Amazfit has now released a new high-end smartwatch featuring an AMOLED display. Available globally, the Amazfit T-Rex Dual Solar boasts up to 180 days of battery life, as well as up to 3,000 nits peak brightness and offline maps support.

Amazfit has now launched the T-Rex Dual Solar globally. For context, the new smartwatch arrives shortly after a detailed specification sheet leaked online. As expected, the T-Rex Dual Solar leverages a 1.32-inch AMOLED display with a claimed 3,000 nits peak brightness.

Incidentally, this is the same peak brightness value as the Cheetah 2 Pro and Cheetah 2 Ultra that arrived earlier this year. Likewise, Amazfit rates the Bip Max for up to 3,000 nits peak brightness too. However, the T-Rex Dual Solar surpasses those three smartwatches when it comes to battery life.

Thanks to front and rear-facing photovoltaic solar panels, the T-Rex Dual Solar is said to extract up to 25 days of battery life from its 660 mAh cell. Reportedly, exposing the smartwatch's front solar panel to 50,000 lux of sunlight for three hours per day extends its battery life to 34 days, though. Moreover, solar charging Amazfit's new smartwatch using its rear panels under the same conditions supposedly delivers up to 51 days of battery life, or up to 180 days with outdoor extreme mode enabled.

For reference, this peak battery life claim falls short of Garmin's for the Fenix 9 Pro Solar. As we have discussed separately, the Fenix 9 Pro Solar boasts up to 291 days of battery life in power-saving mode. The T-Rex Dual Solar achieves its extended battery life with an AMOLED display though, rather than the lower-contrast and slower Memory in Pixel (MiP) panel used in the Fenix 9 Pro Solar.

The T-Rex Dual Solar combines a sapphire crystal display with a titanium housing, too. On top of that, Amazfit pre-installs offline maps and other features like hybrid training tools. The T-Rex Dual Solar is available to order from September 22 for $649.99, £649.90 and €649.90 in the US, UK and the Eurozone, respectively. Orders should start shipping by mid-October in Europe but right away in the US. Please see Amazfit's website for more details.
