Amazfit T-Rex Dual Solar Smartwatch - Basalt Black

The Amazfit T-Rex Dual Solar is a premium rugged outdoor GPS smartwatch designed for endurance athletes, mountain climbers, and professionals working in extreme environments. Launched as the 2026 flagship model, it solves the primary limitation of high-performance smartwatches: battery anxiety during extended expeditions. By integrating solar harvesting technology on both the front display and the rear glass-ceramic casing, this watch provides a continuous energy supplement from sunlight, significantly reducing the frequency of manual charging.

Constructed with a Grade 5 Titanium bezel and back cover, the T-Rex Dual Solar is built to withstand mechanical stress and environmental exposure. It serves as a comprehensive navigation and health-monitoring tool, offering offline mapping, dual-band GPS, and the BioTracker 6.0 PPG sensor. Whether you are trekking through remote trails or monitoring recovery after high-intensity training, this device provides the data and durability required for serious outdoor use.

Dual-Sided Solar Charging Technology

The standout feature of this model is the world's first implementation of dual-sided solar charging in an AMOLED smartwatch. While traditional solar watches rely solely on a transparent layer over the screen, the T-Rex Dual Solar utilizes two distinct harvesting surfaces:

• Front Solar: A specialized layer integrated into the AMOLED display that converts sunlight into power without compromising the 3,000-nit peak brightness or color accuracy.
• Rear Solar: A solar panel integrated into the glass-ceramic back of the watch. This allows the device to capture ambient light even when the watch is removed from the wrist or resting on its side.

Under optimal conditions (50,000 lux), the front solar panel can extend the typical 25-day battery life to approximately 34 days. When combined with rear solar harvesting, the total battery life can reach up to 51 days. In low-power Clock Mode with sufficient sun exposure, the device can operate for up to 180 days.

Display and Visual Performance

Equipped with a 1.32-inch AMOLED screen, the watch delivers a resolution of 466 x 466 pixels and a pixel density of 353 PPI. The display is protected by synthetic Sapphire Glass, which provides superior scratch resistance compared to standard mineral glass. The 3,000-nit peak brightness ensures that text and maps remain legible even under direct, high-altitude sunlight.

Navigation and Tracking Systems

For backcountry navigation, the T-Rex Dual Solar utilizes a circularly polarized GPS antenna and supports six satellite positioning systems. This configuration improves signal reception in dense forests or deep canyons where standard GPS often fails.

• Offline Mapping: Download full-color maps and contour lines directly to the watch.
• Route Management: Features turn-by-turn navigation, automatic rerouting if you deviate from the path, and advanced waypoint markers.
• LiveShare: Share your location in real-time with emergency contacts or teammates.
• Ski & Trail Tools: Includes specialized ski maps and a navigation gradient curve to visualize upcoming elevation changes.

Health and Fitness Monitoring

The BioTracker 6.0 PPG sensor offers high-precision biometric data. The watch monitors heart rate, blood oxygen saturation (SpO2), stress levels, and Heart Rate Variability (HRV) around the clock. For athletes, the Zepp Coach training plans provide AI-driven guidance based on your current fitness level and fatigue.

The device supports over 180 sports modes, including recreational diving up to 50 meters, trail running, and mountain climbing. Advanced metrics such as VO2 Max, Training Load, and Recovery Time help users optimize their physical performance and avoid overtraining.

Frequently Asked Questions

Does the solar charging mean I never have to plug it in?
Solar charging is designed to supplement the battery and extend its life between charges. While it can significantly prolong the duration—up to 180 days in clock mode—it does not entirely replace the need for conventional magnetic charging, especially with heavy GPS usage.

Is the titanium used in the watch hypoallergenic?
Yes, Grade 5 Titanium is widely known for its biocompatibility and is generally suitable for users with sensitive skin or metal allergies.

Can I use the watch for scuba diving?
The watch is rated at 10 ATM and supports recreational diving up to 50 meters. It is not intended for professional saturation diving or depths exceeding 50 meters.

How do the offline maps work?
Users can download specific regions via the Zepp App over Wi-Fi. Once downloaded, the maps are stored on the watch's internal memory and can be accessed without a cellular or internet connection during your trek.

What is the purpose of the red light on the flashlight?
The red light mode is designed to preserve your night vision and reduce the attraction of insects while providing enough illumination to read a map or navigate a campsite.
