Product Details
Amazfit T-Rex 3 — Smart Watch (Onyx)
Rugged expedition platform — dual-band positioning, global maps, 27-day battery and extreme environmental certification
Built for explorers and professionals, the T-Rex 3 combines a military-grade 316L stainless-steel bezel and impact-ready chassis with an ultra-bright 1.5" AMOLED for reliable readability in full sun. Dual-band GNSS, offline global maps and industry-leading battery life (up to 27 days typical) make it a dependable tool for multi-day expeditions, while extreme temperature, humidity and pressure ratings ensure the watch keeps working when the environment is most demanding.
Expedition-Grade Durability with Modern Sports Intelligence
T-Rex 3 is designed as a bridge between adventure hardware and modern wearable intelligence. The watch provides global, phone-free navigation with route import and turn-by-turn guidance; multi-day autonomy from a large 700 mAh cell; and a comprehensive set of biometric sensors and analytic engines that produce actionable training and recovery insights. Corrosion-resistant 316L stainless steel, sealed controls, and certifications for heat, cold and water make the watch resilient in extreme contexts.
Performance figures are manufacturer-stated. GNSS performance, battery run times and sensor accuracy depend on configuration, environmental conditions and usage.
Core Capabilities
Dual-Band, Multi-Constellation Positioning
Dual-band GNSS tapping six satellite systems reduces multipath and improves positional stability in canyons and dense urban terrain. Use imported routes, offline global maps and turn-by-turn voice guidance for true phone-free navigation on remote treks.
Rugged Materials & Environmental Certification
316L stainless-steel bezel, sealed buttons and an impact-ready chassis are designed to operate from −22 °F to 158 °F (−30 °C to 70 °C). The watch is rated 10 ATM and certified for freediving to approximately 45 m for serious water sports.
170+ Sports Modes & AI Training Plans
Choose specialized modes for ultramarathon, triathlon, surfing, strength, hiking and more. Zepp AI generates progressive training plans and delivers on-watch performance metrics—VO₂max, training load/effect, recovery time and Daily Readiness—to optimize progression and reduce injury risk.
Comprehensive Health & Recovery Insights
Continuous heart rate, SpO₂, stress and HRV monitoring, combined with sleep staging (including REM), breathing quality and morning recovery reports, provide a full picture of physiological readiness. PAI® and recovery metrics translate complex data into actionable guidance.
Smart Functions & Voice Control
Zepp OS supports notifications, music control, camera remote, weather & tide info, voice control (built-in mic), and speech-to-text replies where platform support exists. The watch also surfaces important expedition tools: digital compass, barometric altimeter and storm alerts.
