The Amazfit T-Rex 2 is a chunky sports watch made for the outdoors. It’s about 47mm wide and 14mm deep, and it has a big 1.39-inch screen. It has exposed screws on the wide bezel and four buttons, two on each side, that help you move around the watch and add to its rugged look. The size and design are similar to the Fenix 7, but unlike the Fenix 7, you can’t customize the watch to make it less bulky. For example, you can’t choose a 42mm size or a rose-gold bezel.
The watch only weighs 66g, so all that weight doesn’t come with too much extra weight. For reference, the basic Fenix 7 is 47mm and weighs 79g. As someone with pretty small wrists, I thought the watch looked pretty big, and I wouldn’t wear it in the evening with a summer dress. However, it felt surprisingly light. Of course, the way the watch looks is up to the user, and some people will probably want to wear a big, bulky sports watch. After all, if you’re going to spend your weekends climbing El Capitan, why not let everyone at work know?
The bright 1.39-inch AMOLED screen with a resolution of 454 x 454 pixels is what really stands out about the design of this watch, despite its small size. It really is bright and clear, and it’s easy to see while moving, even in bright sunlight. As we’ve seen with watches like the Fenix 7 and the Forerunner 955, the screen can also be used as a touchscreen. However, like Garmin watches, you can still use the buttons to move around the watch if your fingers are wet or sweaty. The watch comes with a silicone strap, which is pretty common for sports watches these days. It’s worth noting, though, that the silicone band seems to be attached to the watch with screws that don’t look like normal ones. If you like to change the strap on your watch, it might be hard to do so.
When deciding whether or not to buy an Amazfit watch or fitness tracker, the battery life is always a big plus, and the Amazfit T-Rex 2 is no exception. It takes about two hours to go from empty to fully charged, and in “battery saver” mode, it can last up to 45 days.
Again, if you compare this battery life to that of its main competitors, it does well. Garmin’s Epix Gen 2 can be used as a smartwatch for up to 16 days and as a GPS-only device for up to 42 hours. In smartwatch mode, the basic Fenix 7 model that can’t be charged by the sun can last up to 18 days, and in GPS-only mode, it can last up to 57 hours. In smartwatch mode, the Instinct 2 can last up to 28 days, and in GPS-only mode, it can last up to 30 hours. The Instinct 2, on the other hand, has an unlimited battery life because it can be charged by the sun.
One of the main reasons to buy a sports watch is to track different activities, and the Amazfit T-Rex 2 has a lot of ways to do that. The watch has more than 150 sports modes, and each one can be changed to show different data screens during different activities. Once you turn on the watch’s ExerSence algorithm, it can automatically track eight sports, like running, swimming, cycling outside, and walking.
When it comes to tracking different workouts, the watch has all the metrics you’d expect, from the simple time, distance, calories burned, and heart rate to the more technical training load, anaerobic capacity, and VO2 max. The watch also has “training templates,” which are basically workout plans that you can use on your wrist.
There is sleep tracking, a built-in barometer and compass, and a multiband GPS, which is very impressive for a watch at this price point. During testing, I found that the GPS was just as accurate as my Garmin Fenix 7, which was ever so slightly clearer but still very impressive.
If you buy this watch for a multi-day trail running trip or a long hike, you should know that some of the mapping features listed on the website are not yet on the watch. At the time of writing, you can’t upload GPX maps to the watch. You can only use the breadcrumb feature to get back to the beginning of your run or trail. This should soon change, though.
The watch has triathlon and multisport modes, which are also impressive for a watch at this price point. I tried for weeks to connect a third-party sensor to the watch, like my Bluetooth heart rate strap, but I couldn’t figure out how. After a lot of searching, I got in touch with Amazfit, who told me that this wasn’t possible. Like most watches, the heart rate isn’t nearly as accurate as it is on my chest strap. If you can’t connect the two, I’d say this is a big problem for anyone who is training hard for a race.
From a smartwatch point of view, the watch lets you see your smartphone notifications, but you can’t respond to them yet. When enabled, you can swipe left from the home screen to see your notifications at a glance. There’s a weather widget that lets you see the day’s forecast at a glance, and you can add widgets like your calendar, menstrual tracking, and breathing to the watch.
When paired with your phone, the watch lets you play, pause, and skip music on your phone, so you don’t have to dig around in your pocket or pack while you’re hiking. You cannot, however, put music on the watch.
During testing, I also liked the camera remote app. When connected to an iPhone or Android device in camera mode, it lets you use the watch as a remote for taking selfies in the middle of a hike. I also thought it was cool that you can download a GoPro app to the watch and use it to start and stop videos on your GoPro when it’s connected. This watch is definitely made for people who like to go on adventures on the weekends.
The Zepp app, where you can see all of your workout and sleep data, is the thing I like least about the Amazfit. Compared to Garmin Connect and Fitbit Premium, it’s just cumbersome and not very easy to use. The metrics are split between the homepage and the “Health” tab. There are a lot of them, but there is no advice on what to do with all of them.
Overall, the Amazfit T-Rex 2 is a good watch for people who want to spend around $200 and want a lot of features. You could easily use this for most of your activities, and it can track pretty much every sport under the sun. Still, not everyone will like the chunky design or the Zepp app, especially if you’ve used something like Garmin Connect.
If you want a Garmin around this price, the Forerunner 55 is the brand’s entry-level running watch, and it will get you through most races without any trouble. With a little more money, you can get the newer Forerunner 255, which is a very impressive watch that fits in a smaller package and has modes for more than one sport.
The Amazfit T-Rex 2 is a good choice for weekend adventurers on a budget because of its bright display and long battery life. Just be ready for the inevitable dinosaur jokes.
