*The colors may differ slightly from the image. Features These G-SHOCK G-SQUAD GBD-H1000 Series models pack heart rate measurement and GPS capabilities into a choice of black or white designs made of semitransparent resin. The result is powerfully vibrant timepieces that look great no matter where they are worn. Useful workout functions include an optical sensor for heart rate measurement, along with bearing, altitude/barometric pressure, and temperature sensors, and an accelerometer for step counting. These five sensors help to keep you in close touch with your current activity in real-time. The ability to receive GPS signals lets you access location information when you need it. When used in combination with the stopwatch, you can keep track of running information like distance, speed, pace, and more. The watch uses your heart rate and speed data to calculate a VO2max value, which is an indicator of your cardio-pulmonary capacity. This measurement is useful when trying to increase stamina for running and other activities. A phone app is available to help you configure watch settings and manage your training data.
