T-Rex 3 Rugged/Military Smart Watch 48mm, GPS (with Privacy), Offline Maps, Long Battery Life,328 Feet Water-Resistant, 170 Fitness/Sport Modes, AI, Voice Control, for Android or iPhone, Black

I switched from an Apple Watch to the TRex. The main reason I wanted to switch was battery life. The Apple Watch at best could get 24-30 hours, but general use 24hrs was my average. I looked at the Garmin Fenix 8 but I really just didn’t want to pay that price. I watched review after review and felt the TRex was the right fit for my needs. Concerns before I purchased: - messaging - calls - no Speaker I have had the device now for about 45 days. Durability - this is a solid watch. I have been doing a full kitchen gut and remodel. I have warn this watch the whole time and it looks like me. No scratches or evidence of any damage. Battery Life - I think confidently 18 days is consist. The first few days I was messing with the settings and looking it over a lot so battery was only 10 days after charging to 90%. I think you could get even more if I turned off notifications and brightness down. Navigation and menus - the OS is really smooth. Very fast to respond. I like the mix of buttons and touch screen. Especially when you have gloves on and such Insights and Health - I think it is far more accurate on steps than my Apple Watch. I wore both watch’s on the same wrist for a full day and I never realized how many non steps my Apple Watch was picking up. I was sitting and typing at my desk. The Apple Watch picked up a nearly 100 phantom steps. The TRex picks up stress pretty well. It notices when I am thinking about a topic that is stressing me, like “is my flooring going to arrive in time?” Or “we only have x hours to complete this before the contractors are here!” Lots of good health habit reminders and such. I am looking forward to getting more use out of them once this project is over. Price, quality, and worry - when you have an expensive watch you worry about damage. It’s not to say I don’t worry about this watch, but when it’s 1/3 or 1/5 of the price of the other watches you looked at, it’s nice to be able to just enjoy it. Lots of compliments on its appearance and screen brightness. A lot of watch for the process The gaps: I do have moments I wish I could do a voice reply to a text or quick reply, but Apple doesn’t allow that. No speaker is a kind of a bummer and I typically don’t pair my headphones to my watch, but that would be nice to be phone free for a run or workout. Overall, I really like the watch. I thought I would miss the Apple Watch integrations, but I don’t. The TRex still has the camera remote and find my phone features. I don’t really notice anything yet that I miss from my Apple Watch that I would say is a “send it back!” Thing. Updates are fast and so far little tweaks will continue to improve it. I would by it again.

This is quite simply the very best smart watch I've ever owned. It doesn't just beat the name brands, it far surpasses them. I've owned 2 Samsungs, Garmin, Google and a Fitbit. Nine of those even remotely compared to this. I've owned it for about 8-9 months now and it never ceases to amaze me how much better it is than Anything else I've ever owned. Battery life is incredible. I typically get about 3 solid weeks before it needs charged. All the measurements it records (steps, distance, heartbeat, blood oxygen, etc are accurate and precise. It's indestructible and it looks good too. I have absolutely nothing negative to say about this amazing watch.

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!

After nearly a week of use, I love this watch. It's not very large or heavy, so wearing it non-stop is a breeze. The companion app, Zepp, works very well for tracking your health and workouts. Being that I wanted something more durable, the build quality is excellent as is the battery life. I lose around 5% charge per day, which is very acceptable. Watch face options are plentiful. In a nutshell, the best smartwatch I've owned. One I can recommend.

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!

I have used another brand for years and was skeptical switching to the Amazfit but I must say that this offers more than the big brands when comparing the price difference. What one gets out of this value is a well deserving smartwatch. This smartwatch offers a lot of functionalities and features and it doesn't cost as much as other big brands. It fits very well and I do not get wrist fatigue as I had with previous other brand which also gave me rash over and over. It provides a little little deeper/more sleep tracking information while. Step counts seem on point as well. This watch offer a lot for features that one would have to pay more for. It covers blood oxygen, Altimeter, GPS, heart rates/health, exertion, calories, natural sounds for meditation or just relaxation, etc. This is a great smartwatch for lesser the price as compared to the big name brands. It looks great and I get lots of compliments too.

I'm pretty impressed with this watch. I had a fitbit and it quit on me, so I upgraded to this. I'm still not used to it yet and the navigation is a little clunky, but thats MY learning curve and not the watch. I tried a few different watch faces, tweaked some preliminary settings. So far so good. Its a LOT bigger than I expected, but it's light and comfortable, I'll get used to that - but it LOOKS like it's built for battle-rattle. The strap is better than I expected, I was planning on replacing it if needed, but that won't be necessary. The app setup was super easy, and the app itself deserves some praise. I was honestly expecting the app to be a little bit half-azzed, but it's actually really slick, coming from the Fitbit, it seems like it has way more information and a better layout. I have it set to show the HB/M live so its constantly sampling and updating, I like that for the curiosity/novelty factor, and the watch face I chose shows the outdoor temp which it gets from BT connectivity to my phone, thats actually really cool. I shut off all the social media alerts and music controls, I don't need any of that jazz buzzing me all the time. Im just interested in the health stuff and the Date/Time. If this thing lasts a couple/three years (and it obviously should with so few charging cycles) I'll be very happy with this. All things considered - quality of the device, the health app, the many cool different watch faces to pick from, the functionality of the phone/text messaging, music/social media/text (not using but you might), IMO its worth the money.

This watch is great, but unfortunately limited by the Zepp OS. For example, you have to set clock alarms manually on the watch even when you simply want to replicate what you already have on your phone: It is missing direct/native syncing between Google Clock alarms and Amazfit watches. Also the Calendar sync feature doesn't let you select which calendars to sync. It assumes you want to sync all calendars from your phone.

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 a few weeks now, and I’m genuinely impressed. If you are looking for a watch that can take a beating while still offering the feature set of much more expensive premium brands, this is the one. What Stands Out: Build Quality: It feels incredibly durable. It has that rugged "G-Shock" aesthetic but feels much lighter and more comfortable on the wrist than I expected. I’ve taken it hiking and through some rough gym sessions, and it doesn't have a single scratch. The Display: The screen is brilliant. It’s bright enough to see clearly even under direct sunlight, and the colors are very sharp. The increased screen-to-body ratio compared to previous models makes reading notifications and workout stats so much easier. Battery Life: This is the highlight for me. I’m a heavy user—tracking workouts and keeping notifications on—and I’m still only charging it once every couple of weeks. It’s a huge relief not having to worry about a nightly charge. Fitness Tracking: The GPS accuracy is spot on, and the sheer number of sports modes is overkill in the best way possible. The data syncing with the Zepp app is smooth, and the health insights are detailed and actionable. Final Verdict: For anyone into outdoor activities, heavy strength training, or just someone who wants a watch they don't have to baby, the T-Rex 3 is a steal. It offers a premium, high-end experience at a fraction of the cost of the main competitors. Highly recommended!

Utilizo o T-Rex desde sua primeira versão, meu T-Rex 2 com o tempo acabou sofrendo alguma oxidação em seus sensores e a medida dos batimentos acabou ficando imprecisa, mas com o T-Rex 3 estou amando a precisão e suas funções. Realmente é um bom relógio de entrada e para quem quer alinhar os benefícios fitness e de estilo para usar um relógio no dia-a-dia.

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! 🙏🏽
