Combining a sleek look and sophisticated monitoring, the GTS 2 GPS Smartwatch from Amazfit is an ideal companion that looks great while helping you stay healthy and reach your fitness goals. It sports a 1.65′′ square AMOLED display that is your window into detailed health and fitness monitoring. To help you stay fit in the exercise of your choice, the GTS 2 supports 90 built-in sport modes, 6 of which are conveniently automatically recognized, and GPS tracking. With waterproof construction that can withstand depths of up to 164′, the GTS 2 can be used on land and in the pool. To better track how your body responds to exercise and its overall health, the GTS 2 also comes equipped with both a BioTracker 2 24/7 heart rate monitor and blood-oxygen saturation (SPO2) sensor. While you can get detailed metrics on the watch or in an app on your phone, an algorithm combines all of this data into a singular PAI score for easy tracking of overall progress. With additional features, such as hands-free calling, notifications, and sleep monitoring, the GTS 2 GPS smartwatch provides support throughout your entire day.
