Having recently reviewed the Amazfit Balance 2, a smartwatch that impressed with its perfect hybrid of rugged durability and lifestyle features, I was eager to experience the latest from Amazfit, the T-Rex 3 Pro. Unlike the Balance 2, the T-Rex 3 Pro takes on a much tougher, outdoorsy persona crafted for adventurers and endurance athletes. With a grade 5 titanium bezel, sapphire crystal glass, and military-grade certification, this watch immediately signals its rugged intent. Despite the robust build, it doesn’t sacrifice the smart essentials one expects from premium brands like Apple or Samsung, including Bluetooth calling, texting, and advanced offline navigation. All of this comes at a competitive price of ₹34,999, making it a compelling option for those wanting serious performance at half of the cost of premium competitors.
Design and Controls
The design of the Amazfit T-Rex 3 Pro is impressive, built with a grade 5 titanium bezel and buttons housed within a fibre-reinforced polymer case that balances ruggedness with lightness. Weighing just 52 grams without the strap, the watch feels surprisingly light on the wrist, making it comfortable for all-day wear, even during intense physical activities or prolonged use. On putting it on, the lightness is immediately noticeable, a rare quality for a watch with such a tough exterior, and this makes it ideal for outdoorsmen who don’t want their gear to weigh them down.
The watch features four well-placed functional buttons along the case that provide easy access to multiple features, including a rotating crown that doubles as a selector and a back button among others. One of the unique, practical highlights is the integrated dual-light LED flashlight, which you activate with the side buttons. It offers various modes, including a bright white beam, a red light for night vision, an SOS flashing mode, and a high-lumen boost mode for intense brightness. This feature ensures that the watch is as ready for camping or nighttime hikes as it is for daytime adventures.
Certified to military standards MIL-STD-810G and with a 10 ATM water resistance rating, the T-Rex 3 Pro is designed to withstand extreme shocks, water exposure, and temperatures as low as –30°C. The watch is also diving-certified up to 45 meters, making it suitable for recreational diving. The straps, while lightweight and breathable, are a bit tricky to attach due to the durable securing mechanism, but once on, they remain firmly in place and comfortable, adding to the overall outdoor appeal.

Display
The T-Rex 3 Pro boasts a vibrant 1.5-inch AMOLED display (480 x 480 resolution, 322 ppi) that reaches up to 3,000 nits brightness, ensuring excellent visibility even in harsh sunlight, a must-have for outdoor wearers. The sapphire glass provides enhanced scratch resistance and clarity, preserving the immaculate look and touch responsiveness despite rugged use. The watch balances a minimal bezel profile, maximizing screen real estate for ease of fit and excellent readability without bulkiness.
What stands out is the watch’s capability beyond fitness, offering Bluetooth calling and texting functionality seamlessly from the dial. This is a rare and appreciated inclusion in a smartwatch designed primarily for rough use, as it saves users from pulling out their phones during activities. Being able to respond to messages or take calls directly makes it a handsome blend of adventure tool and daily driver, further increasing its utility compared to typical sports watches.
Advanced Maps and Navigation
One of the biggest upgrades with the T-Rex 3 Pro is its preloaded offline contour maps, designed for hiking, trekking, and skiing. It supports turn-by-turn navigation with auto rerouting if you go off-course, as well as POI (Point of Interest) search directly from the watch without needing a phone. There’s also a round-trip route planning feature that can automatically generate running or hiking paths, plus ski maps and slope data for winter sports enthusiasts.
The navigation suite is powered by dual-band, 6-satellite GPS, ensuring high-precision tracking even in dense forests, remote mountains, or urban canyons. This transforms the T-Rex 3 Pro into not just a fitness tracker, but a serious outdoor exploration tool.
Software
Running on the upgraded Zepp OS 3.5, the T-Rex 3 Pro offers a smooth, intuitive software experience, optimised for both performance and user convenience. The OS ensures swift navigation through its menus, notifications, and apps without lag, even when multitasking with GPS tracking, music playback, or health monitoring. Refined animations and touch response elevate the overall user interface, delivering reliability expected from a premium smartwatch.
A notable enhancement is the full integration of Zepp Flow, a powerful AI voice assistant allowing users to control the watch using voice commands. While this feature is still maturing, it adds a valuable hands-free layer of interaction, especially useful in scenarios where manual input isn’t practical, such as hiking or cycling.
Processor and Storage
The T-Rex 3 Pro handles its extensive suite of features without any hiccups. This hardware combination ensures smooth operation of smart functions like app launching, Bluetooth calls, offline music playback, and real-time notifications. The generous 26GB storage allows music files and offline maps to be saved directly onto the device, facilitating long trips without a phone.
The processor, coupled with Zepp OS, delivers a responsive and fluid interface, making switching between workout tracking, health monitoring, and daily alerts seamless. Users can expect stable performance whether trekking through rough terrain or managing daily logistics, reflecting a well-optimized balance of power and efficiency in the device’s core components.
Health and Fitness
Amazfit has equipped the T-Rex 3 Pro with more than 180 sport modes, catering to everything from trail running and hiking to recreational scuba diving and strength training with auto-rep detection. Unique modes like HYROX training and race modes target professional athletes, while casual users benefit from comprehensive tracking for activities like cycling, swimming, and walking.
Health monitoring is state-of-the-art, featuring the advanced BioTracker 6.0 PPG biometric sensor that provides highly accurate data even in challenging outdoor conditions. It continuously monitors heart rate, blood oxygen saturation (SpO₂), stress levels, sleep quality, and breathing patterns. For those who want even greater accuracy, Amazfit’s optional Helio Strap, an arm-worn heart monitor, can pair with the watch, delivering pro-grade health metrics.
Environmental sensors, including a barometric altimeter, ambient light sensor, gyroscope, and temperature sensor, provide additional valuable data, enabling comprehensive situational awareness during outdoor activities. The in-depth health analytics available through the Zepp app include AI-powered energy monitoring, providing users with a dynamic score that balances workout intensity, recovery, and stress, helping optimize training and prevent burnout. These insights are provided subscription-free, offering meaningful data without additional costs.
Battery
Battery life is one of Amazfit’s defining strengths, and the T-Rex 3 Pro excels in this department. The 48mm model’s 700 mAh battery offers up to 25 days of typical usage, covering health tracking, notifications, and occasional GPS use without needing frequent charges. Heavy continuous use with GPS reduces this to about 10 days, which is still exceptional compared to competitors like the Apple Watch or Samsung Galaxy Watch.
For dedicated GPS tracking during extended treks or races, the watch supports multiple power-saving modes, delivering up to 38 hours in precision GPS mode and up to 85 hours in power-saving GPS mode. This endurance frees users from charging anxiety during multi-day adventures or remote expeditions.
Charging uses a magnetic USB-C dock and takes roughly an hour for a full battery recharge, which is reasonably quick given the large capacity. The integrated dual-light LED flashlight also extends battery conservancy by using minimal power while providing crucial illumination when needed.
Verdict
The Amazfit T-Rex 3 Pro is a standout in the outdoor smartwatch category. It skilfully combines rugged, military-grade durability with the full suite of smart features today’s users’ demand. Whether it is the state-of-the-art health and sport tracking, advanced offline maps and navigation, or the crystal-clear display and communication features, the T-Rex 3 Pro offers a holistic experience tailored for avid adventurers and fitness enthusiasts.
Priced around ₹34,999, it offers tremendous value, rivalling premium brands with far higher price tags. Its versatility, from long battery life and advanced GPS navigation to the comfortable, lightweight titanium design, makes it an ideal companion for anyone seeking a tough yet smartwatch for everyday and extreme use.
