Is now a good time for you to upgrade to a premium solar-powered smartwatch?
Amazfit has officially released the T-Rex Dual Solar smartwatch, a rugged wearable that incorporates solar collection on both the display and the device's back plate. The unit is currently available for purchase at a retail price of $649.99.
Why it matters
The device is engineered to address power limitations in remote environments by supplementing its internal battery through ambient light exposure. This development marks a move toward integrating dual-surface energy harvesting into high-end consumer wearables.
The watch pairs a 660 mAh battery with a display capable of 3,000 nits peak brightness and a Grade 5 titanium chassis. The system delivers 41 hours of runtime in Accuracy GPS Mode and offers 10 ATM water resistance.
The players
Amazfit
A consumer electronics brand specializing in smart wearables and health-tracking hardware.
Zepp Health
The parent company behind Amazfit, focusing on health-focused IoT products and proprietary sensor technology.
The details
Solar energy is harvested through a combination of the AMOLED display and a glass ceramic back plate. To manage power consumption, the device includes a Solar Priority Mode that forces an ultra-low-power state to facilitate energy recovery. The hardware is housed in a titanium bezel with sapphire crystal for structural durability.

The Tech Race
The T-Rex Dual Solar enters the competitive market for rugged endurance wearables by adopting dual-sided solar harvesting. This approach positions the device against high-end Garmin products that have established a benchmark for solar-extended operation in wilderness conditions.
The watch is available now for $649.99 for users requiring extended operation away from traditional power sources. Its 10 ATM water resistance makes it suitable for recreational diving, though performance in low-light environments will rely solely on the 25-day standard battery capacity.
The takeaway
The T-Rex Dual Solar shifts the battery life baseline for heavy-use GPS scenarios by utilizing dual-surface solar recovery. Users should watch for real-world independent benchmarks confirming how the solar harvesting performs under varied geographic latitude and seasonal light availability.
