Amazfit T Rex 3 Pro review
A rugged outdoor watch that delivers outstanding value, with a few smart compromises
After a full month of daily wear, workouts, and outdoor testing, the Amazfit T Rex 3 Pro leaves a clear impression. This is a smartwatch built for people who care more about durability, battery life, and reliable tracking than app ecosystems or lifestyle smarts.
At roughly half the price of flagship rugged watches, it delivers a confident, well judged experience that prioritises the essentials and largely gets them right.
It does not try to be everything. Instead, it focuses on being a dependable outdoor companion, and that clarity of purpose is what makes it so appealing.
Design and build
The T Rex 3 Pro looks exactly like what it is meant to be: a serious outdoor watch. Its chunky, purposeful design nods to classic digital sports watches, but the execution feels modern and refined rather than bulky for the sake of it.
The combination of a fibre reinforced polymer case with a Grade 5 titanium bezel strikes a smart balance between toughness and weight.
The 1.5 inch AMOLED display is one of the standout features. With a peak brightness of 3,000 nits, it remains clear and legible even under harsh sunlight.
Sapphire crystal protection adds reassurance for anyone who regularly scrapes past rocks, gear, or door frames. Physical buttons are well placed and easy to use with gloves, something touchscreen only watches still struggle with.
A welcome addition this generation is the choice of two sizes. The original 48mm version will suit larger wrists and those who prefer a bold presence, while the new 44mm option makes the watch far more accessible for smaller wrists or everyday wear.
Features and fitness tools
The feature set leans heavily toward outdoor sports and endurance activities. With over 180 sport modes, including skiing, snowshoeing, and diving, the T Rex 3 Pro clearly targets adventurers rather than casual step counters.
Offline maps, multi band GPS, and detailed route tracking make it a strong option for trail runners, hikers, and cyclists who spend time away from phone signal.
Water resistance up to 10 ATM and certification for diving to 45 metres add to its credibility as a true adventure watch. It even includes a dedicated dive mode, placing it in direct competition with far more expensive models.
There are a few everyday conveniences too. NFC payments via Zepp Pay work reliably, and the built in LED flashlight is surprisingly useful during night runs, camping trips, or power cuts. Health tracking is comprehensive, covering heart rate, blood oxygen, sleep, and recovery metrics, and accuracy is consistently impressive.
What you will not find is deep third party app support. Music streaming apps, messaging platforms, and navigation tools are absent, and there is no LTE option. These omissions are deliberate, but they will matter depending on what you expect from a smartwatch.
Performance and battery life
Performance is where the T Rex 3 Pro quietly shines. GPS locking is fast and stable, even in challenging environments, and distance tracking holds up well against more expensive competitors. Heart rate and blood oxygen readings are consistent and trustworthy across workouts and rest periods.
Battery life is one of its biggest advantages. Even with heavy use, including always on display and regular GPS workouts, it comfortably lasts over a week. With lighter use, stretching toward three weeks is entirely realistic.
For long hikes, ultra runs, or multi day trips, this kind of endurance is a genuine luxury.
The weak spot is the Zepp Flow AI assistant. While voice commands can work well for launching activities, the experience quickly becomes inconsistent.
Errors are not handled gracefully, and failed interactions tend to end conversations rather than recover them. It feels like a feature with potential rather than a reliable tool today.
Outstanding value for the right kind of user
The Amazfit T Rex 3 Pro is not trying to replace a phone or compete with lifestyle focused smartwatches. Instead, it delivers rugged hardware, excellent tracking, and exceptional battery life at a price that undercuts most serious rivals by a wide margin.
If you want cellular connectivity, advanced safety features, or a rich app ecosystem, you will need to spend more. But if your priorities are durability, outdoor performance, and value for money, the T Rex 3 Pro is one of the most compelling options available right now.
