#1 Design & Price
Amazfit GTR 3 vs T-Rex Pro
Starting off with the design, Amazfit GTR 3 leans towards a sleek and refined look with its 45.8mm resin and aluminum frame, designed to feel both lightweight and sophisticated on the wrist. Weighing just 43g, it’s remarkably comfortable, especially for users who prioritize an unobtrusive fit. This smartwatch comes in Thunder Black and Moonlight Gray, showcasing a minimalist, versatile aesthetic. The GTR 3’s interface includes a responsive OLED touchscreen and a practical rotating dial for effortless menu navigation, adding a modern touch with physical functionality. Priced at $179.99, it offers a balance of elegance and efficiency, making it an appealing choice for those wanting a versatile wearable that doesn't overwhelm the wrist.
On the other hand, T-Rex Pro's design is built for rugged durability, catering to users who value endurance. Its 47.7mm polycarbonate body, coupled with four substantial metal buttons, presents a chunky, military-inspired look that feels sturdy on the wrist. Weighing in at 59g, it is slightly heavier than the GTR 3 but prioritizes durability with military-grade toughness, including shock resistance, extreme temperature tolerance (-40°C to 70°C), and 10ATM water resistance (down to 100m). Available in Meteorite Black, Desert Green, and Steel Blue, this model also stands at the same price point of $179.99, offering a choice for adventurers who need a resilient companion without compromising on features.
#2 Health & Workout Tracking

Health and fitness tracking on the Amazfit GTR 3 impresses with its broad selection of over 150 activity modes. The watch tracks steps, calories, and sleep while providing SpO2 monitoring and heart rate tracking for comprehensive health insights. It also includes PAI (Personal Activity Intelligence), which turns your health data into an easy-to-understand score, giving users clear motivation to meet activity targets. The GTR 3’s advanced sleep tracking is a bonus, offering insights not only into sleep stages but also capturing naps. This model is also equipped with a multi-satellite positioning system that includes GPS, GLONASS, GALILEO, BDS, and QZSS, ensuring robust tracking accuracy for outdoor workouts.
Amazfit T-Rex Pro
The T-Rex Pro, meanwhile, is equally dedicated to health tracking, with its Bio-Tracking 2 PPG optical sensor monitoring heart rate and SpO2. The watch also features an extensive range of sensors, such as an accelerometer, gyroscope, altimeter, and geomagnetic sensor. Designed for fitness enthusiasts, it measures VO2 max, enabling users to see their oxygen consumption during exercise, which is a helpful indicator for aerobic endurance. While both models offer automatic workout detection, the T-Rex Pro also includes a unique “virtual rabbit” mode, allowing you to compete against your previous run times. Despite the broad data it collects, however, some users may find the absence of contextual feedback on the T-Rex Pro limiting.
#3 Smart Features
Amazfit GTR 3
Regarding the smart features, Amazfit GTR 3 presents a smooth, user-friendly interface powered by an efficient operating system, offering a generally bug-free experience. It includes a practical microphone for Alexa voice commands, making it possible to check the weather, set reminders, or control smart home devices directly from the wrist. The GTR 3 lacks music storage but can control media playback on your smartphone and even features remote control for the camera, which is a handy addition for group photos or solo shots. Also included are smart features such as water-drinking reminders, BMI calculation, and a colorblind checker, making it not only fitness-focused but also mindful of daily wellness.
Amazfit T-Rex Pro
While the T-Rex Pro skips Alexa integration, it compensates with unique features tailored for outdoor adventures. It includes essential alerts like incoming call, text, and app notifications, alongside weather updates, sunrise and sunset times, and a moon phase tracker, making it particularly useful for hikers and outdoor enthusiasts. However, it lacks onboard music storage and a voice assistant, potentially limiting its appeal for those looking for more extensive smart features. The T-Rex Pro does offer flashlight functionality, but its brightness may be too dim for practical use. The GTR 3 may appeal more to tech-savvy users, while the T-Rex Pro remains focused on outdoor utility.
#4 Battery Life

Battery life is a standout on both models, though they cater to different usage levels. The GTR 3 boasts up to 21 days on a single charge under typical usage, scaling down to 10 days with heavy use. This longer-lasting battery allows for consistent tracking and use of smart features without the frequent need for recharging, ideal for those with a busy lifestyle.
The T-Rex Pro, powered by a 390mAh battery, holds its ground with 18 days of typical use, reducing to around a week with active GPS usage and high-intensity tracking. While slightly less than the GTR 3 in total longevity, it still aligns well with the demands of most users, especially adventurers who may rely on it for shorter, high-impact trips. Both models use proprietary magnetic chargers, ensuring quick and efficient charging without hassle.
#5 Connectivity
Amazfit T-Rex Pro
The GTR 3 and T-Rex Pro support Bluetooth for smooth smartphone integration. The GTR 3’s strong GPS performance is matched with multi-satellite support, adding reliability in challenging environments. Additionally, the T-Rex Pro offers a comparable GPS experience, incorporating dual-band capabilities that make it a top pick for off-the-grid locations. Neither watch includes Wi-Fi, focusing connectivity through Bluetooth and a reliable GPS experience.
