First of all, I used to work for a major smartwatch company (which will remain nameless) writing manufacturing test software and running the data analytics team. Thus, I was very much involved in the device data set uploaded to the cloud and the creation of device diagnostics, usability, and user preference analytics for our marketing and engineering departments. From this point of view, I was very intimate with all the internal device components and how our devices were utilized by our users. I would have to say that this T-Rex3 watch blows away any of the smartwatches I have seen in my previous company at a reasonable price point. It even has more comprehensive feature set than I have seen on my Garmin Venu 2 which I use everyday for my workouts. I wore both the Venu 2 and T-Rex3 on a long hike and the health and workout numbers were very close. Been using this Venu 2 for 4 years now almost everyday and I consider this to be the gold standard for GPS accuracy. I cannot stress how much battery longevity is a high priority to me as I know many users do not want to charge their devices daily as people forget and it is a hassle. I personally make my smartwatch purchase decision starting with how long the battery will last. BTW, I also owned an Apple Watch in the past and I stopped using it as I would forget to charge it daily, rendering it useless to me. Pros - Excellent battery life, almost 2 weeks using the GPS daily every day for at least 1 hour in my workouts. I believe the battery can run longer without such heavy GPS usage. - Cost to own. You will not find a better, more comprehensive smartwatch at this price point. - I have proven its GPS and health feature set accuracy - I like that it can capture Beidou GPS signals as I travel to Asia frequently - Large high resolution color screen for my old eyes to see everything clearly - Comprehensive set of watch faces, some free but some you must purchase - Comfortable enough for me to wear 24/7 to enable me to collect sleep data - Most of the settings and features like notifications are pretty standard for today's smartwatches - Durability of this device to meet military standards suggests it should last...time will tell Cons - It is a large watch, but it fits me. 42mm is my ideal size, but some may find it too big. - Very functional design, not the prettiest, but also not the ugliest - Appeals primarily to men which locks out 50% of the market who wants this feature set - Zepp app is average at best. For instance, I cannot track the mileage on my running shoes like on the Garmin app. I still like the Garmin app better.

Click to play video If you’re adventurous like me and need watch, get this now! After a few weeks with the Amazfit T-Rex 3, I can say it’s a true powerhouse for anyone who loves the outdoors and staying active. This smartwatch is built tough — its military-grade body, 328-foot water resistance, and very easy to set up mean I can confidently take it with me on water sports adventures, hikes, and any unpredictable terrain. The AMOLED display is a standout. It’s super bright, so I have no issues checking maps or workout stats even in bright sunlight, and the night mode is easy on the eyes when I’m in lower light plus it’s scratch resistant. The battery life is exceptional; with over three weeks on a typical charge and hours of extended GPS, it’s perfect for long weekends away or days when I’m constantly on the move. One feature that’s been a game-changer for me is the one-tap health indicator through the Zepp Health app. It lets me check my heart rate, oxygen levels, and stress in seconds. The variety of workout modes keeps things interesting, and the personalized AI training plans help me stay on top of my goals. The GPS accuracy and offline maps have been reliable, and the built-in compass adds peace of mind when I’m exploring new areas. The watch faces are fun to switch up based on the day, giving the T-Rex a bit of a customizable edge. Overall, the Amazfit T-Rex 3 is a solid companion for outdoor enthusiasts and travelers who want both durability and smart functionality. It’s not just a smartwatch — it’s become an essential part of my everyday routine!

This Is my third Amazfit watch. Each time I have upgraded to a model with more features. These watches are bulletproof, stylish, and feature-rich. They are a great value at a fraction of the price of the other brands. One of my favorite features of this watch is the ability to have a visible clock face showing 24/7. The watch is loaded with features, and I have no complaints at all. I did order a replacement nylon band because silicone bands tend to give me a rash. If I had one small criticism, it would be the stock silicone band that comes with the watch.

The NFC feature and the blood pressure monitor feature does not run in MENA region, so that hefty price tag of Aed800 plus really does no justice unless you are happy paying extra for the screen size bump 1.39 inch to 1.50 from the T Rex 2 and the offline maps. I've got the T Rex 2 and the T Rex ultra, but this one is a sure disappointment for me.

One of the best smart watch of segment. Rugged built, nice looks. Performs flawlessly during work outs. The data measurement is also accurate. I have just shifted from samsung galaxy watch 6 to this watch and am just amazed with the features provided and the battery management. I feel samsung should learn from amazefit.

Amazfit , please fix this with the next update. I was walking and the “Speed” data was showing half my actual speed, the real speed should be the displayed data X 2. If we do the math, the image I provided doesn’t make sense as the speed displayed was way to fast for a walk. I have not done the other workout apps yet ,but i hope they are calculated the right way. Other than the mentioned, really happy with the purchase, Thank you! 🙏🏽
