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.

A great value useful everyday smartwatch
It's slightly bigger than the old Trex 2 but performs in a similar way. The charger has become a c type and you get a small adapter thats magnetic which sticks to the rear of the watch. Charging is pretty rapid and the battery does last for weeks. I bought mine to monitor my health heart rate etc and in that regard it's pretty useful. The Zepp app links to your watch and will give you a comprehensive feedback on your activities. There is a subscription service should you wish to get ongoing assessments of your health and workout activities. On the wrist it's comfortable and being waterproof and quite tough will still function in and out of water. I found the slightly larger screen useful for reading downloaded maps. It's fairly simple to set up and practically useful on a daily basis. My old watches have become redundant. Would I recommend it yes I would. It's far cheaper than many similar smart watches and every bit as useful. There are literally hundreds of watch faces to choose from free and paid for, the latter being quite cheap too. A very good smart watch.

A Rugged Powerhouse for Outdoor Adventurer watch
I’ve been using the AMAZFIT T-Rex 3 for over a month now, and it’s hands down one of the best outdoor smartwatches I’ve owned. Built like a tank yet surprisingly sleek, it’s packed with features that make it perfect for serious adventurers and fitness enthusiasts. 🛰️ Navigation & GPS Accuracy: The dual-band GPS and support for 6 satellite systems make navigation incredibly accurate, even in remote areas. The offline maps feature is a life-saver when hiking in places with no signal. It locks onto satellites fast and keeps the route tracking consistent and reliable. 📱 Display & Durability: The AMOLED display is bright, sharp, and readable even under harsh sunlight. The rugged design looks tough and can definitely handle rough use – perfect for trails, water, and all types of outdoor sports. 💪 Fitness & Sports Modes: With 170+ sports modes, it covers everything from running and strength training to freediving up to 45m! It’s also got advanced metrics that fitness lovers will appreciate – heart rate, SpO2, VO2 Max, recovery time, and more. 🔋 Battery Life: This is where the T-Rex 3 shines. I got close to 3 weeks of battery life with moderate use (notifications on, GPS workouts 3–4 times a week). Even with heavy GPS use, it holds strong for days. You won’t need to charge it every night like most smartwatches. 💳 Extras – NFC & App: NFC payment support is a cool addition, especially when I don’t want to carry my wallet during workouts. The Zepp app syncs quickly and offers a clean interface to review health stats, routes, and sleep tracking. ✅ Final Verdict: The AMAZFIT T-Rex 3 is a beast of a watch – feature-rich, ultra-durable, and built for real adventure. Whether you’re a hiker, diver, cyclist, or just love the outdoors, this watch delivers on performance and battery life. Plus, it looks great on the wrist! Would 100% recommend to anyone who wants a reliable outdoor companion. 🔥

Ich liebe alles an dieser Smartwatch. * Das Display ist nicht nur gestochen scharf, sondern auch die Farben sind zum Verlieben schön. * Sie hat alle Sensoren und Features, die man braucht. * Bietet unglaublich viel Speicher für offline Karten, MP3-Files etc. * Hat Bluetooth und WLan. * Eine recht brauchbare App für's Handy. * Ist nicht zu schwer und auch nicht zu teuer. * Der Akku hält super-lange. Nach einem halben Jahr Benutzung wüsste ich immer noch nichts, das ich an dieser Smartwatch auszusetzen hätte.

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.
