Amazfit T-Rex 3 Military Smart Watch 48mm, Fitness Watches with GPS (with Privacy), AI, Voice Control, Offline Maps, for Android or iPhone, 170 Sports Modes, 328ft Water-Resistant, Black

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!
