The Amazfit T-Rex 3 in Lava is a rugged smartwatch designed for those who push their limits in demanding environments. It features a 1.5-inch AMOLED display with a peak brightness of 2,000 nits, ensuring that your data remains visible even under direct sunlight, all protected by Gorilla Glass and a 316L stainless steel bezel. The build combines a polymer middle frame with a liquid silicone strap, resulting in a durable yet manageable weight of 68.3 grams for the case. This watch is built to withstand extremes, operating in temperatures from -30°C to 70°C and offering 10 ATM water resistance, which includes certifications for freediving up to 45 meters. Inside, the device runs on Zepp OS 4 and utilizes the BioTracker™ 6.0 PPG sensor to monitor your heart rate and blood oxygen levels. You can track your progress across 177 sports modes or use the dual-band positioning with six satellite systems for accurate offline maps and turn-by-turn navigation. The 700 mAh battery provides significant endurance, lasting up to 27 days with typical use or 180 hours in GPS max mode, so you can spend more time exploring and less time tethered to the magnetic charging base. For added convenience, the built-in microphone supports the Zepp Flow™ AI assistant, and a dedicated glove mode allows you to interact with the screen while wearing gear up to 2mm thick.
