Amazfit has added a new member to its T-Rex series of rugged smartwatches. The new Amazfit T-Rex 2 comes with some significant upgrades over the first-gen T-Rex. It has a larger 1.39" AMOLED display, while the company has upped the water-resistant property from 5 ATM (50 meters) to 10 ATM (100 meters) here. T-Rex 2 also has a significantly larger battery, which is now rated to last up to 24 days under normal usage. With all this, the watch is a bit heavy compared to its predecessor, as it weighs around 66.5 grams with the strap. In terms of health monitoring, it comes with some advanced features like breathing exercises and menstrual cycle tracking as well. Whereas you can choose from 150+ sports modes along with 15 strength training exercises. Amazfit T-Rex 2 boots on the company's own "Zepp OS" platform and pairs with the "Zepp" app which is available for both Android and iOS devices.
