Review: Best Smart watch I've ever owned - One year in and I've only had a great experience with this T-Rex - 3. Battery life is insane, with normal usage sometimes 16 days between charges, I swim with it, sleep, with it, wash it weekly, strap is comfortable, functions all work simply and easily for me to get on with my daily tasks. And it's tough, I've lost count of how many times I've accidentally bumped it against the SUV's door or stairs railing or wall, no visible scratches on the case or glass. Will honestly recommend to any active person who wants a no nonsense, long battery life tough Smart Watch. Oh, and it costs much..much less than "famous" brand competitors and does the same things, with 10 x more battery life between charges. Honestly the best tough Smart Watch I've ever had. And I've had watches before thst cost 3 x more than this one.
Review: A solid 5-star smartwatch! - I’ve used both Apple Watch and Samsung watches, and the Amazfit truly surprised me — it outperforms them in almost every aspect. What impressed me most is its seamless integration with the iPhone — you get nearly all the functionality of an Apple Watch, except for things like Apple Pay. The design, in my opinion, looks far more elegant, and the battery life is phenomenal — I get about 10 to 12 days per charge, even with heavy daily use and gym sessions. All that at a fraction of the price of an Apple Watch. It’s an easy recommendation for anyone looking for performance, style, and endurance in one smartwatch.

## Features

- Large, Bright Display: The AMOLED display can reach peak brightness of 2,000 nits; read your maps and workout data easily in any light. Night mode reduces eye strain in the dark, and Glove Mode keeps the screen responsive when wearing 2mm thick gloves.
- Built for Adventure: Endure any challenge with a 316L stainless steel bezel and buttons. The military-grade body can resist 158°F heat and -22°F cold. Water-resistant to 328 Feet, the watch is great for surfing and can be used for freediving to a depth of 147 Feet.
- Over 3 Weeks of Battery Life: The Amazfit T-Rex 3 smart watch can last for 27 days with typical use, 42 hours in GPS Accurate Mode, and up to 114 hours in GPS Long Battery Life Mode. With some settings disabled, GPS usage can even last up to 180 hours for long hikes.
