T-Rex 3, Smart Watch, 1.5" AMOLED Display, GPS, iOS/Android

Great value, very good and accurate step counter, wake up alarm and many more things. I had an Apple Watch and this buy far exceeded my expectations. Easy to set up and the app makes its seamless. Set durable and. It bulky which was a surprise. Very comfortable and happy I took the risk, I think it is far better value than Apple Watch …. Not to mention the battery life is far more superior and lasts several days

I’ve owned both Apple Watches and Garmin watches, and honestly, the Amazfit T-Rex 3 has become my favorite of the bunch. It offers what I consider the best of both worlds: the smart features and ease of use that people love from Apple, combined with the rugged durability, fitness tracking, and outdoor capabilities that Garmin users appreciate. The only features it lacks compared to an Apple Watch are the ability to take phone calls directly from the watch and reply to text messages. For me, that’s not important at all. I actually prefer having fewer distractions while still receiving notifications when I need them. Where the T-Rex 3 truly shines is battery life. Instead of charging every day or every other day, I can go for extended periods without worrying about finding a charger. That alone makes it far more practical for everyday use, travel, outdoor activities, and workouts. The health and fitness metrics are also excellent. Heart rate monitoring, sleep tracking, stress monitoring, recovery data, activity tracking, and workout metrics have all been accurate and useful. The Zepp app presents the information clearly and gives meaningful insights without overwhelming you with unnecessary complexity. The build quality is outstanding. The watch feels premium, durable, and ready for anything. Whether I’m in the gym, at work, hiking, or just wearing it casually, it looks great and performs flawlessly. The display is bright, responsive, and easy to read even in direct sunlight. What impressed me most is the value. You’re getting features that compete with watches costing significantly more while maintaining incredible battery life and ruggedness. Amazfit has created a watch that delivers nearly everything most people actually need without forcing daily charging or a high price tag. If you’re trying to decide between an Apple Watch, Garmin, or Amazfit, don’t overlook the T-Rex 3. For anyone who values battery life, health tracking, fitness features, durability, and overall value, this watch is an absolute winner. It’s easily the best smartwatch I’ve owned and one that I would purchase again without hesitation.

Absolutely loving this watch. Far superior to the Apple Watch, yet just as easy to use. The band is super comfortable and the watch is lighter weight than my Apple Watch was. The battery life is absolutely astounding! Literally almost never have to charge it, and when I’d it’s fast. The display gives so many options for the face to allow you to see anything and everything you need. It’s face is the perfect size for visibility . I’ve really been enjoying tracking my sleep (I have sleep apnea, which I already knew), and it’s actually catching the same and sometimes more interruptions than my c-pap does. I have been monitoring my heart rate, my steps, tracking my diet and so much more utilizing the app and it’s so easy! Definitely recommend!

So far, after using the watch for a week now, I am impressed. I've used other smart watches and this has been the best so far. Seems some of the difficulties I've experienced with watches in the past are better with this T Rex 3. BT connectivity is better. No issues linking up to my phone. And when loosing connectivity due to distance or such, the watch and the Zepp app seem to reconnect very well. I do not, and have not had to go through any BT reconnect process since my first pairing. The heart rate monitor seems much more reliable than other watches. The sleep pattern and logging of such seems very accurate and reliable as well. As with most watches, lots of functions and apps I'll never use, but the ones I do use, seem to work well. I like the excersize tracker functions. One of the features I never thought about, but once playing around with it, I have found it very useful in incorporating into my routine. I did notice the compass and GPS all seemed to calibrate and function much quicker and with more accuracy with this T Rex 3. I was pleased with that result. The mapping feature is working and kind of interesting. Not a feature I've used before, but can see where it could be worthy of trying. The ability to use phone, SMS and such works well, with replies and messaging working well paired with my Samsung Galaxy. In general, typical features found on this watch all seem to work as advertised. The Zepp app has many, many features which seem to be interesting, but haven't yet played around with. No issues with downloading or pairing or data updates from the watch. All in all, seems like Amazfit and Zepp work very well together. As with most smart watches, the navigation through its apps and functions can be "trial and err", but I find this watch to be very near others and no more difficult while being and very similar to others. The Zepp app can be intrusive with permission requests and such, but always having, and giving the option to allow or deny. All depends on what the user finds useful or not. Watch itself is very lite on my wrist. I'm not a big fan of the band, more like a plastic, silicone band, but works fine, just not my preference. Display is very nice and bright, clear and crisp. Battery seems to be working as advertised as well. Vibration intensity and volume of the watch is beyond sufficient. All in all, very pleased with this purchase and would recommend this watch. Don't have any real downsides to it yet. In using this watch and considering it's cost, I can't image why anyone would spend more for other watches. Seems this watch is very near perfect with all the bells and Whistles anyone would need at a reasonable price.

EXCELLENT EXCELLENT purchase!!! Beautiful watch, tones of features THAT WORK! Lots of accessories available, especially if you buy the watch band adapter for 22mm bands. App is extremely easy to use and very helpful, set up and connection was a breeze. Battery id outstanding. I have EVERYTHING turned on to test it including Always on feature, and 100% lasted 7 1/2 days down to 23% which is when I recharged it. Recharging was slower than my Garmin but still only took about an hour. Workout features and biometrics are really good!

This watch is everything it says it is. Awesome display, and way more tracking info, apps and other useful things than the fruit watch. I wore it for 9 days before I charged it and even then it was at 20%. It’s solid, tough and comfortable enough to wear 24/7, which I do. Sleep and steps metrics are accurate, I checked them against my phone and my CPAP machine metrics. Great watch at a great value.

I watched many, many reviews on many, many watches before making this decision. Awhile back, I owned a fossil smart watch. They are now discontinuing those. I wanted to make the jump to something that had built in GPS (and ability for downloading offline maps) for when I am hiking in the woods on camping trips. I also wanted accurate heart rate, and vo2 sensors. Baromiters, altimeters, and compass are also handy. Naturally, I looked at Garmin, Samsung, even google for smart watches. I found 3 main problems when looking at these: 1) They are all very expensive for the feature set I wanted. 2) They all lack the battery life I need to be safe in the woods. 3) When compared side by side to the watches by Amazfit, they really weren't better enough to even come close to justifying the price. On top of that, this battery on the Trex3 is absolutely insane! Things I was worried about concerning the Trex 3 was the size of the watch. In the pictures I saw in reviews, the thing looked ridiculously large on a wrist. Well, those pictures must have just been a bad angle because this thing barely larger than my wonderful old fossil smart watch. It looks great and I won't feel like an idiot wearing it to my upcoming business conference :) . The Zepp app took a minute or two to figure out (and quite a while to download for some reason) but it is wonderful. Great metrics from my hikes and runs on the watch and the app. The built in gps is nearly flawless. It both locates quickly and tracks precisely. I freakin' love it. Even the sleep tracking this first week seemed pretty damn accurate. That was a real shock and we'll see if it continues, but I am hopeful. The free watch faces to choose from are all cool and range from tacticool to business casual cool to Harvey in Suits cool. The watch band (mine was the red one and the Trex3 comes with it, a liquid silicone band) is SOOO comfortable. The watch feels light on my wrist. I may swap this band out for a 22mm leather one from my fossil for the upcoming business conference. (the Trex3 comes with an adapter for the quick release watch bands we all know and love). A very long time ago (i think about 5 or 6 years ago) I bought a cheap Amazfit fitness tracker watch that cost like 50 bucks. It was just OK. Not great, and the app kinda sucked. My lord, I had no idea just how far this innovative company has come. Their whole line of watches since then look pretty damn good. And this rugged Trex3? It's my dream come true. Worth every penny so far. For $270 bucks? Just get it. Garmin and Samsung won't miss your $700 investment in their products. And you won't miss a beat. Or their vastly inferior battery life.

Ok! I have had this for about 3 weeks now. Initially I purchased this based on functionality for hiking and battery life. Let me say this.. I just gave the watch it's second charge. It lasts me roughly 14 days before needing a charge and even then it was still at 24%. I use it moderately heavy. As far as a sleep tracker it seems better than what I had via my Samsung watch. I don't think I'll ever go back to phone branded watches. The battery life on Pixel, Apple watch, and Samsung is complete garbage compared to this. I get those are running an OS but so is this. It has not lost connectivity to my Pixel phone once. The GPS is extremely accurate. I barely lost battery on a 5 mile hike while using dual band GPS. The functionality of the watch is great. It's very easy to navigate and get your settings tailored to the way you workout or just live your life. The Zepp app is also very easy to navigate. The display is bright and there are plenty of free watch faces to choose from. I do enjoy the sleep tracker although at times it won't record it due to movement during sleep. I also think it tracks steps better than the other phone branded watches. Far less phantom steps. I highly recommend this watch if you're looking for a whole bunch of options at an extremely fair price.

The reason i bought was the battery life. I am getting 14 days with always on Display and 25-30 days with always on display off. Light weight wonderful watch and full of features.

I’ve been using the Amazfit T-Rex 3 for some time now, and honestly, this watch has exceeded my expectations in almost every way. The first thing that instantly grabs attention is the incredibly bright and crystal-clear 1.5-inch AMOLED display. Even under direct sunlight, the screen remains sharp, vibrant, and super easy to read thanks to its impressive 2000 nits brightness. The rugged premium design with stainless steel detailing gives it a true adventure-watch feel while still looking stylish enough for daily wear. One small thing I personally noticed is that while the Amazfit T-Rex 3 has an absolutely gorgeous and ultra-bright AMOLED display with 2000 nits peak brightness, deep blacks, and excellent outdoor visibility, I still felt that the display clarity and crispness on the CMF Watch Pro 2 looked slightly sharper and cleaner to my eyes in normal day-to-day usage. The T-Rex 3 display is bigger, more rugged, and designed for outdoor adventures, maps, workouts, and extreme visibility, whereas the CMF display feels a bit more refined and visually polished for regular UI elements and text clarity. Performance-wise, the watch feels amazingly fluid and smooth. Navigating through menus, apps, workout modes, maps, and features is fast and seamless. The UI is clean, responsive, and packed with useful features. I’m genuinely impressed by how many functions and smart tools Amazfit has included without making the experience feel laggy or cluttered. From health tracking, sleep monitoring, heart rate and SpO2 tracking to offline maps, dual-band GPS, AI features, and 170+ sports modes — everything works beautifully and reliably. Battery life is another area where this watch absolutely shines. Getting up to 14-15 days of battery backup on a rugged smartwatch with such a bright display and powerful GPS features is seriously impressive. It easily becomes a reliable companion for travel, workouts, outdoor activities, and everyday use without constantly worrying about charging. Overall, the Amazfit T-Rex 3 feels like a perfect combination of toughness, premium quality, smart functionality, and smooth performance. It delivers flagship-level features at a very impressive value, and every day of usage makes me appreciate it even more. Definitely one of the best rugged smartwatches I’ve used so far.

Good

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! 🙏🏽

O Amazfit T-Rex 3 superou todas as minhas expectativas. É um relógio muito bom, extremamente resistente e com uma construção robusta que passa muita segurança no dia a dia e nos treinos. A tela touch é excelente, muito fluida e responde rápido aos comandos. Em termos de funcionalidades, ele é super completo: vem com vários itens e métricas detalhadas para atividade física, atendendo muito bem a qualquer tipo de treino. O GPS funcionou direitinho, mostrando-se muito preciso nos trajetos. Além disso, todos os resultados das atividades podem ser facilmente emitidos e conferidos no aplicativo, que é muito prático e intuitivo. Para tudo o que oferece — incluindo os mapas offline e a longa duração da bateria —, penso que o custo-benefício dele é excelente. Recomendo muito!
