The GBD-H1000, equipped with a heart rate monitor and GPS functions, is a color model that uses G-SHOCK's brand colors of black and red as its base colors and skeleton resin. 1A9JR is based on the standard black color and has a gold IP bezel covered with skeleton resin, giving it a special look. The 4A1JR is red. The 4A1JR, on the other hand, uses red as its base color, with a black IP bezel and black skeleton resin. In terms of functions, the watch uses 5 sensors and GPS to monitor your workout in real time, and supports evaluation, analysis, and planning of your training in conjunction with a dedicated application. In addition to the optical sensor for heart rate measurement, it is equipped with an accelerometer for step measurement and sensors for orientation, altitude/barometric pressure, and temperature to help you monitor your workout in real time. In addition, it obtains your current location information from GPS satellites. It can also measure your distance, speed, and pace. It can also measure VO2max, the standard for cardiopulmonary capacity, based on measurements such as heart rate and running speed. This can be used as an indicator to strengthen endurance in running and other activities. The dedicated application, which helps you manage your watch settings and training, allows you to check your current fitness level and training progress, as well as automatically create a training plan to meet your set goals. The exterior design features a curved back cover to reduce interference with the back of the hand, a soft urethane band for a better fit, two-color molded buttons for easy operation, and a high-definition MIP LCD for better visibility. The watch is also compatible with USB charging and solar charging, enabling solar-powered daily use (clock function, step counting, notification function), in pursuit of practicality.
