How do you top a watch called the T-Rex that boasts all manner of certificates to prove its toughness? You build it to qualify for even more certificates and call it a Pro.
That’s what Amazfit has done with the T-Rex Pro outdoor smartwatch, which has passed 15 military-grade tests for toughness (compared with the paltry 12 the T-Rex managed) and beefed up the waterproofing from 5ATM to 10ATM. The watch also now has a blood oxygen saturation sensor, and 40 hours of GPS battery life rather than the 20 of the T-Rex.
The T-Rex Pro has 100 different sports modes, and a variety of sensors to ensure accurate tracking, including four different satellite systems for location data, a heart rate sensor and a barometric altimeter.
These sensors sit beneath a 1.3in (33mm) always-on AMOLED display, which is impressive given the battery life of the watch. Amazfit estimates you’ll get through 18 days of typical use or nine days of heavy use, which would involve more regular tracking of outdoor activities using the GPS.
Part of the reason behind that strong battery life is that the T-Rex is not a true smartwatch. It doesn’t run an operating system like Google’s Wear OS, which means it doesn’t offer apps. It also doesn’t have on-board music storage or wireless streaming, though it can control the music on your phone.
There are weather forecasts and smart notifications, but it’s probably better to think of it as a sports watch with a smartwatch-style screen, rather than something that’s comparable to the Apple Watch or Samsung Galaxy Watch 2.
Along with sports tracking there’s also sleep tracking, which includes a breakdown of your time in different sleep stages like REM or deep sleep. That tracking is enhanced with heart rate variability monitoring, which helps assess when your body is under periods of physical stress and when it’s getting a well-earned rest.
You also get a Personal Activity Intelligence health assessment from the watch. This provides you with a score based on your past seven days of activity, with the goal of keeping your score above 100 to improve or maintain your cardiovascular health.
The Amazfit T-Rex Pro will be available in the UK from 31st March and is competitively priced, to say the least, at just £139 – a real snip for the features and design quality you’re getting. On paper, that is. We’ll give our full verdict on the watch once we’ve had a chance to test it properly.
