Great quality and value
Don’t write many reviews but I’m really impressed with this watch. I previously had an Apple Watch but lost it and didn’t want to pay for an overly expensive watch. After doing a lot of research I opted for the T-Rex 3 which was on offer. Was dubious about the size as I have small wrists and hands and upon opening the well packaged and presented box it did seem big. However, once on my wrist the size didn’t seem to matter anymore. It is remarkably light and very comfortable to wear. The strap has enough notches for any sized wrist and they’re close together so you can get the tightness just right. I have slept with it on and you forget it’s there. The screen is large and vibrant and setup is very simple. There are a vast number of features and they all work very well and nothing appears too complicated. There are plenty of settings to play with and lots of free watch faces to choose from and you can customise what your watch displays. Overall I am hugely impressed with this watch. Has the feel of a more expensive watch, loads of features that work well and a brilliant battery life.

The Smartwatch that is Smart
Was looking to replace my current smartwatch which was no longer supported by a well known brand....criminal after 5 years not to be supported and the watch cost £350. So I was determined not to buy a high street brand again. Did my research and found this T-REX high on the recommendation list. I have had it nearly a week and I am very impressed. For £230 you get a very nice and sturdy watch that looks good and not too bulky. In my opinion nearly all your fitness data is gathered by your heart beat or bpm. I measured the watch against a professional heart rate monitor and I can honestly say the watch was within +/- 2bpm from a range of 55 to 170bpm, running or cycling, very impressive so I know my workout data will be accurate. Using the app called Zepp syncs with the watch and also my training app called TrainingPeaks to record all my data as I am a keen cyclist I also do some running. Again impressed with the Zepp App, easy to use and works well. I have had my watch on now for 5 days, used GPS, heart rate monitor is on all the time, screen comes on with a flick of the wrist (I wear it in bed) and I still have over 70% battery life...I am impressed. The watch is packed with widgets you can use and change the watch interface, there are many to choose from but there could have been a lot more in my opinion but as I use the old fashioned LCD style I am very happy. Charging the watch is easy as it comes with a USB powered magnetic charger. A slight design fault is if you use the wrist band that comes with the watch you have to lie the watch on its side to charge it. No harm done. What was a nice feature is that they included adaptors so you can change the strap to any 22mm width strap which I have done with a brown leather strap which I can now charge the watch lying flat. Notifications arrive onto the watch very fast from my mobile and the screen quality is very good. I am discovering new things with it as the instructions are sparse but I think that is a good thing as you can explore yourself as you can't delete anything. I was advised to buy a much dearer watch as I wanted to do interval running training which times each interval, well guess what this watch has interval training and worked a charm last night and with multipoint GPS tracking the data is very accurate.This watch gets a clear 5 stars and all the reviews about it were right, excellent value for money and very happy with the purchase, you know the one....the one that puts a smile on your face knowing you made the right decision.

Great watch! Smartwatch equivalent to a G shock!
Great watch!! So I needed a new watch for work as my old Casio G shock died after a few years. As I work as an electrical engineer on the underground power network, I needed a strong watch that was durable in outdoor conditions. I was tempted to buy another Casio G shock but liked the idea of a smart watch but didn’t like the idea of needing to charge it every 1 or 2 days and thought they were a little delicate for what I need it for. After some research I decided to go for the Amazfit T rex 3 and wasn’t disappointed! Pros; Battery life, with daily use battery lasts over 20 days! Sturdy, very well built, don’t feel nervous about using it in extreme conditions, I brought a glass screen protector just for some extra protection Very easy to use and fully of features, very quick and responsive. Cons; Size, it’s not a slim watch, it’s quite chunky which for my I don’t mind as I can live with that trade off for the extra strong built quality and plenty of battery life but just bare in mind it may be a bit too thick to slide under most long sleeves. Connectivity, it’s not laggy at all but there has been a few instances where I’ve missed notifications and the watch has lost connectivity with my phone so I’ve had to open the app and sync it and it starts working again. It’s only happened a few times so not a big deal. Too many features, this can be a pro and con but I find it packed with that many features it can sometimes feel overwhelming and most of the apps and features you’ll hardly use or they don’t work very well. Such as the work out app, it’s great if you’re going for a run but if you’re having a gym workout, the app doesn’t accurately measure reps and most the time you want to have a workout and just get on with it rather then fiddling with your watch the whole time. Overall I’d recommend it, great value for money even though I missed out on the Black Friday deal and paid £253, at £210 on black Friday it’s a no brainer, you’d easily pay a lot more for a garmin equivalent.

Brilliant watch – tough, reliable, and great for fitness!
I’ve been using the Amazfit T-Rex 3 for a while now and I’m seriously impressed. The battery life is unreal — I barely have to think about charging it — and it’s handled everything from gym sessions to long walks without any issues. The build feels really solid and durable, and the screen is bright and easy to read even outdoors. It’s packed with features but still simple to use, which I love. For the price, it genuinely feels like you’re getting way more than you paid for. Definitely one of the best fitness watches I’ve owned!

Was een van Amazon retail tweedehands maar alleen de doos was beschadigd verder horloge als nieuw. Blij mee werkt goed en bijna €130 goedkoper dan de nieuwe.

Die T-Rex ist beileibe kein Dinosaurier, sondern eine moderne, gutaussehende Uhr mit vielen Verwendungsmöglichkeiten. Viele Healthfunktionen, wie Puls, Blutsauerstoff , Schlafqualität usw, lassen ansich keine Wünsche übrig. Man kann eine Vielzahl an Trainings damit tracken und dokumentieren. Es gibt einen Kompass, Navigation bis hin zu Skigebietskarten. Auch können sehr viele ZubehörApps und speziell auch sehr viele Zifferblätter heruntergeladen werden, sehr viele davon sogar kostenlos. Aber ein Highlight ist tatsächlich der Akku. Ich hatte zuvor eine Samsung Galaxy Watch, die ich spät jeden 2 Tag laden musste. Die T-Rex hält bei mir gut 3 Wochen bevor ich wieder laden muss und das bei gleicher Verwendung. Das finde ich schon sehr mega. Von meiner Seite her gibt es eine klare Kaufempfehlung.

Great watch. So smooth and battery lasts atleast 10 days with extensive use. Good value for 270 Euros (2700 sek). Easy to change the strap using the tools provided ( any 22 mm strap will work). Excellent app, and watch faces. So stylish looking.
