The world of rugged smartwatches is a battlefield, and Amazfit’s T-Rex series has long been a formidable contender. The T-Rex 3 has already established itself as a tough, feature-packed option for outdoor enthusiasts who don’t want to break the bank. Now, the new T-Rex 3 Pro arrives, raising the bar and posing a crucial question for adventurers: Is the “Pro” upgrade worth the extra investment?
While the T-Rex 3 and T-Rex 3 Pro share the same DNA of durability and outdoor-focused features, a closer look reveals a clear generational leap in design, materials, and functionality that sets the Pro apart as a serious rival to higher-end competitors, such as Garmin’s Fenix series.
A Tale of Two Tough Guys: Design and Materials
The T-Rex 3 already boasts a robust, military-grade build, but the T-Rex 3 Pro takes things to another level. The most significant upgrade is the use of Grade 5 titanium alloy for the bezel and buttons, replacing the T-Rex 3’s predominantly plastic and stainless steel frame. This isn’t just a cosmetic change; it makes the T-Rex 3 Pro more resistant to corrosion and adds a premium feel. The display on the Pro model is also protected by a scratch-resistant sapphire crystal glass, a major step up from the T-Rex 3’s Corning Gorilla Glass.
The T-Rex 3 Pro also introduces a dual-size option, with a 48mm and a more compact 44mm case, catering to a wider range of wrist sizes. This is a welcome change from the T-Rex 3’s single 48.5mm case size, which some users found to be bulky.
Brighter Displays, Smarter Features
Both watches feature bright AMOLED displays, a trademark of the Amazfit T-Rex series. However, the T-Rex 3 Pro’s screen takes a significant leap in brightness, with a peak of up to 3000 nits, compared to the T-Rex 3’s 2000 nits. This enhanced brightness makes the Pro’s display even more legible in direct sunlight, a critical factor for outdoor use. The Pro also boasts a slightly larger display in its 48mm version (1.5 inches vs. 1.5 inches on the T-Rex 3) and a different resolution on the 44mm model.
The Pro also brings some notable smart features to the table that are absent on the standard model. One of the most talked-about additions is the built-in, dual-color LED flashlight, which offers white, red, and SOS light modes—a truly practical tool for campers and hikers. The T-Rex 3 Pro also includes a built-in speaker and microphone, enabling Bluetooth calls and voice control via Zepp Flow, a feature that the T-Rex 3 lacks.
GPS, Navigation, and Health Tracking
When it comes to the core of their outdoor functionality, both watches are well-equipped. They both feature dual-band GPS and support for six satellite systems, ensuring accurate location tracking. Both models also offer free offline maps and navigation features like turn-by-turn directions. The Pro model, however, enhances this with new features like offline map search for points of interest and even includes ski slope maps.
On the health and fitness front, both watches provide a comprehensive suite of features, including over 180 sports modes, heart rate monitoring, sleep tracking, and more. The T-Rex 3 Pro, however, introduces the new BioTracker 6.0 PPG biometric sensor for even more accurate data and the BioCharge™ energy monitoring system, which provides a dynamic score for workout and recovery optimization.
Battery Life and Price: The Final Frontier
While the T-Rex 3 Pro’s enhanced features might suggest a trade-off in battery life, Amazfit has done an admirable job of maintaining impressive longevity. The T-Rex 3, with its 700 mAh battery, offers up to 27 days of typical use and up to 180 hours in max GPS mode. The T-Rex 3 Pro, with its 700 mAh battery in the 48mm version, is also a powerhouse, providing up to 25 days of typical use and up to 116 hours in max GPS mode. The 44mm version has a smaller battery, leading to slightly shorter but still substantial battery life.
This is where the user’s choice becomes most critical: price. The T-Rex 3 is a fantastic value at its price point of around $280. The T-Rex 3 Pro, with its titanium build and advanced features, commands a higher price, closer to $400.
The Verdict: A Pro for a Reason
For those who are budget-conscious but still want a highly capable, durable outdoor smartwatch with excellent battery life, the Amazfit T-Rex 3 remains an exceptional choice. It offers a core set of features that will satisfy most adventurers.
However, suppose you’re a serious athlete or explorer who values premium materials, advanced navigation capabilities, and a few key “pro” features like the built-in flashlight, speaker, and more accurate health sensors. In that case, the T-Rex 3 Pro is a compelling upgrade. It is a testament to Amazfit’s commitment to pushing the boundaries of what a rugged smartwatch can be, and it firmly places the T-Rex series in a head-to-head battle with the established giants of the industry.
