A smooth transition from the 2.5D curved glass to the metal watch body lowers the thickness to 9.4 Millimetre, which makes it slim and delicate. The aircraft-grade aluminum alloy compactness also helps control the weight of the watch body, which is as light as 24.8 gram, but also strong and robust.Water resistant to a depth of 50 meters, Amazfit GTS also supports multiple swimming scenarios. The watch can automatically recognize your swimming position, and record data like SWOLF, pace, or calorie consumption, and enables an accurate analysis on the data each time you swim.Amazfit GTS supports 12 mainstream exercise modes and is integrated with a GPS+GLONASS dual-satellite positioning system, capturing workout tracks accurately. There are also multiple professional sensors that record physical data in full, and perform scientific analysis on them to enhance your exercise capacity.Amazfit GTS combines software and hardware to deeply optimize the power consumption of the system and the components, in order to bring about a long-lasting endurance of 14 days while keeping a slim watch body, which enables you to avoid frequent charges. The watch can continuously work for 1 month and a half under the Basic Watch Mode and up to 25 hours with the GPS continuously working, which is enough for running a marathon or an endurance race.The key information is displayed centrally, focusing on what matters most to you. Except for the time in the upper left corner, there are five display content modules (widgets) that can be customized. In the middle area, you may have weather, heart rate or reminder displayed; in the lower areas, you may switch to stopwatch, alarm clock, battery indicator, or any other of the available 16 options.You can focus on the central time pointer. There are seven customizable display content modules (widgets) to choose from 17 options, so you can view other data in real time.The watch is integrated with Huami’s proprietary BioTracker PPG biological tracking optical sensor, which can perform constant 24-hour high-precision heart-rate monitoring as well as a heart-rate interval monitoring during workouts, and warning if a much too high value is detected. It also supports RealBeats AI-based biological data engine, which is an advanced AI-based automatic identification function for arrhythmia (including atrial fibrillation), to enable you to further learn about your heart’s health, and warn you of potential heart risks. In addition, multi-dimension health management functions such as long-time-sitting reminder, calorie consumption and sleep analysis can help you develop good habits and fully improve the health of your body.
