Description
Amazfit T-Rex 3 is a tough, adventure-ready smartwatch designed for people who need durability, accurate tracking, and reliable connectivity — whether you’re hiking, cycling, diving, or training. It combines rugged build quality with modern smart-watch functionality.Built with a stainless-steel bezel and polymer frame that meets military-grade durability specs, T-Rex 3 is 10 ATM waterproof (suitable for swimming or shallow diving) and resistant to shock, dust and harsh conditions.The watch features a 1.5-inch AMOLED touchscreen (480×480 resolution, up to 2000 nits brightness) — bright and clear enough even under direct sunlight, making it a good companion for outdoor adventures or daytime workouts.For navigation and outdoor tracking, it uses dual-band GPS with support for six satellite systems — this helps maintain accurate location data even in dense terrain or urban canyons. It supports offline maps and turn-by-turn navigation directly on the wrist, which is handy when you’re hiking, trekking or traveling without internet.On the fitness and health side: T-Rex 3 offers 170+ sport/activity modes (running, cycling, swimming, trekking, strength training, and more), AI-powered fitness coaching, and 24/7 health monitoring (heart rate, blood oxygen (SpO₂), sleep, stress, activity tracking). Battery life is a standout — on a full charge you get about 27 days under typical use; even with regular workouts, notifications, and health tracking you can expect 10–13 days — far longer than many other smartwatches. With GPS tracking on, battery life varies depending on usage modeConnectivity options include Bluetooth 5.2, Wi-Fi, and support for the companion app on both Android and iOS, making it compatible with most smartphones.
