These are the latest additions to the new POWER TRAINER sports lineup from G-SHOCK. GBD800UC-5.The good-looking designs and utility colours of these models maximize coordination possibilities with both everyday fashions and training wear. Function-wise, these watches link with the G-SHOCK Connected phone app to provide access to a number of functions that enhance workouts. Daily health and fitness support functions include a 3-axis accelerometer that keeps track of step counts, a Multi-Timer that lets you create up to 20 timer combinations of five timers each, memory for up to 200 lap records, and more. The app also makes it possible to maintain step count logs with five exercise intensity levels, to calculate the calories you burn, to specify a daily step target, to create timer combinations and send them to the watch, to store stopwatch measurement data, to view data, and more. All of this combines to help you plan and record your workouts, making them more effective and enjoyable.

Back wings on the inside of the bands where they connect to the case, a new band ring shape that prevents sliding, and more band holes to allow better tightness adjustment, all add up to a more comfortable fit.
