Casio

The bands of these models have reflectors and other design features that make nighttime activities more fashionable and enjoyable. 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. G-SHOCK Connected also makes it possible to maintain step count logs with five exercise intensity levels, calculate the calories you burn, specify a daily step target, create timer combinations and send them to the watch, store stopwatch measurement data, view data, and more. All of this combines to help you plan and record your workouts, making them more effective and enjoyable. Other features include app-based auto time setting correction and other features for more efficient timekeeping, and an Auto LED Light to facilitate workouts in areas where lighting is dim. Back wings on the inside of the band where it connects 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. You can even make fine adjustments to the band size.
