The G-Shock GD-B500 is a unique fitness-oriented model equipped with Bluetooth smartphone link, a step counter, and a 200-record lap memory. It is also notable for its very light weight and slim size. At 11 millimeters thick, it is currently the thinnest men’s G-Shock watch. The band is designed to fit a large range of wrist sizes (from 5.7 to 7.9 inches), making it suitable for some women.


A daily step goal (from 1,000 to 50,0000) can be set and tracked automatically by the watch, with the goal progress viewable as a graph on the watch display in timekeeping mode. There are also indicators for goal attainment and (optional) step reminder. The step count data and lap records can be transferred to the smartphone app with Bluetooth for viewing, where the 24-hour and weekly step counts are viewable, along with calories burned for each step count category. The daily step count is also viewable on the watch and offers a step count graph for the past seven hours plus the current hour, along with the total step count number. Lap records with lap and split time are viewable on the watch, as well as the phone app.
