Feature Packed and High Quality
Have had this watch for a week and I absolutely love it! It was very easy to set up and linked flawlessly to my Runkeeper account. After several hikes and workouts, the gps is extremely accurate, the heartrate monitor provides valuable info, and there is so much other workout data available! Sleep tracking is making me more aware of how I rest! It is very durable and high quality. No problems seeing screen in full sunlight. I'm on the 10th day since I charged it fully and there is 48% battery left, which is awesome! I can't believe the functionality of this, as there are so many things on the Zepp app that I haven't even been able to fully grasp what all is possible with this watch. Highly recommended for the quality and amount of options and functions for the price!

Durable and bright
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.

Get this now!!!
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!

Great Watch!
I have used this watch every day since purchasing and it continues to impress. First of all, the battery life is simply amazing. Averaging about 3 weeks between charges with normal daily usage. Using a lot of the features does use the battery quicker but still outlasts any other smart watch I have used. Watch receives regular updates which add useful features. TONS of watch faces available, most of them are free. Overall the best smart watch I have ever used.

Amazfit watches are great
Still some of the best smart watches around. I used to own a lot of different watches from other known manufacturers and now they are in a drawer discarded for lack of use. And in another drawer I have all my amazfit watches. I have many but my favorite are the T-Rex watches. I own the T-Rex 2 and now the T-Rex 3. I am still trying to figure out all the T-Rex 3 features and my review will be incomplete for now but I still like this watch. The battery life is less than my T-Rex 2 but it is still a solid 2.5 weeks on how I use it. I also think that I disabled the map feature because it does not show the enhanced display I saw on the advertisement. But like I mentioned, I am still getting used to the watch. The steps compared to my T-Rex 2 are less but more accurate because I think that my T-Rex 2 was more generous. The workout features are great and have a lot more options. The display is larger and better to look at for guys like me with poor eyesight. When I am at the gym I can see things a bit better through the sweat and tears. The notifications are good but sometimes the delay between my phone and the watch is a bit long. I am still trying to figure out things but so far is a good product and a good purchase for me. And the price was good enough for my budget. The T-Rex watches are durable and I really like them. It is too bad that I only wear one watch because I have plenty of amazfit watches to fill one of my arms. When I think about the other watches I feel bad that they may never see the light of day. But I like the T-Rex 3 because because it has a large display and I can see things a lot better. Overall it is a good purchase for me.

Love this watch! Better than Apple!
Amazing display, super clear and unusable amount of apps, but I have one for anything that I wanna do simply amazing great strap flexible, comfortable or workouts even looks good with my suit. I’m super happy about this purchase. I’ve used the sleep tracker and the sleep quality and they both seem to be very accurate. I’ve also used the GPS and location also seem to be very accurate. Amazing quality for each price.

Battery life and functionality are flawless.
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.

Accurate, tough, and perfect for real outdoor adventurers
I’ve been using Amazfit watches for a while and recently switched from the Cheetah Pro to the T-Rex 3. It’s a bit bulkier on my wrist, but it delivers everything I was looking for and more. The GPS calibration is extremely accurate, noticeably better than my previous model, and the overall build gives a rugged, masculine feel that fits perfectly for outdoor use. Battery life is excellent; I can go several days of hiking and mountain outings without worrying about charging. The Night Safety Light is one of my favorite features : perfect for my late-night hikes or mountain descents. You can adjust the screen color between red, yellow, or white depending on the environment, which is surprisingly practical. My wife’s first reaction was, “Woah, it’s so nice”, and I agree. It’s a watch that looks tough yet elegant. If I had to point out one small downside, it’s that the wrist strap can sometimes cause mild irritation after long wear, the same issue I noticed with the Cheetah Pro. Still, for adventurers, hikers, or anyone who loves exploring, the T-Rex 3 is a reliable, accurate, and stylish companion.
