Xiaomi Amazfit A1821 Bip S 1.28" Touch Screen-Bluetooth  Smart Watch Carbon Black (Global Version)

The Amazfit Bip S is designed to be more powerful than the previous generation, thanks to the revolutionary design of the watch materials and manufacturing process while remaining ultra-lightweight. With only 31 grams with the watch band, the watch is very comfortable to wear while doing sport or sleeping. The case is designed with seamless two-color technology to fuse two different shades of polycarbonate material, allowing different colors while ensuring hardness, lightness, and a highly expressive appearance. The Amazfit Bip S uses the Cleaning wristband manufacturing process developed by Huami Technology. Molecular lattice technology ensures the entire wristband is soft, dry, and resistant to dirt, making it perfect for long-term wear. The Amazfit Bip S is built with excellence in mind down to the smallest details, even the buttons. The 316L stainless steel button is finely machined by high-precision CNC machine tools, sandblasted, and treated with a PVD vacuum coating process to make the surface of the button colorful and wear-resistant. In the middle of the button, the watch's color scheme is matched through a tone drip process, which enhances the overall fullness and design details of the watch and adds a finishing touch. The Amazfit Bip S has a color-changing watch body with shades including carbon black, white rock, red-orange, and warm pink to satisfy your desire for color and expression. The ingenious transflective color display allows you to clearly see the screen while taking advantage of low power consumption and eye protection even if the power-intensive backlight is not turned on. It performs even better in outdoor environments, since the brighter the sunlight is, the clearer the display looks, making it ideal for outdoor sports. When the ambient light is low, you can turn on the watch backlight to fully illuminate the screen. The built-in Sony 28nm GPS chip, through several product updates and iterations, as well as continuous optimization and adjustment, performs even better in satellite search speed, positioning accuracy, and power consumption. GPS can operate continuously for 22 hours. Inside the slim body of the Amazfit Bip S, the built-in battery has a capacity of 200mAh. The use of a high-performance switching regulator power chip (low-current high-efficiency DCDC) and optimized Bluetooth reduces power consumption, improves device efficiency, and provides sufficient power for long battery life. The Amazfit Bip S uses the BioTrackerâ„¢ PPG Bio-Tracking Optical Sensor independently developed by Huami Technology. The effective high-precision sensing area is 3 times that of the previous generation, the LED luminous intensity is 7 times that of the previous generation, and the heart rate monitoring accuracy is improved to 98%, all while using only one-fifth the power of the previous generation of products, making this a significant advance for watches with full-day heart rate monitoring. Amazfit Bip S is small, but it contains a lot of potentials. Water Resistant to 5 ATM, it supports 10 sports modes including swim tracking, the continuous heart rate monitoring and PAI Health assessment system provide useful tools to improve your health and workout efficiency. Additional functional and practical features such as music control, editable watch faces, notifications, alarm clock, timer, weather forecast, and world clock will bring more convenience into your daily life and work. The Amazfit Bip S is waterproof to 50 meters. You can wear it while swimming, and also record interesting swimming data, including stroke rate, stroke times, SWOLF index, tracks in open waters, etc. In addition, the watch also supports 10 sports modes, which provide data such as track display, speed, heart rate, distance reminders, and most importantly, excessive heart rate reminders, making you safer when exercising. Amazfit Bip S integrates the innovative huami-PAIâ„¢ Health Assessment System, which eliminates the need to track complicated data and allows you to intuitively understand your physical state at a glance, as well as more concisely and precisely control your health.
