Casio G-Shock G-SQUAD Bluetooth¶ô¶÷ GBD-H1000 Lineup Solar Powered Black Resin Watch GBDH1000-1A4 GBD-H1000-1A4

This model based on the GBD-H1000 series from G-SQUAD, the G-SHOCK sports lineup, comes equipped with heart rate monitor and GPS functions, uses a vivid translucent resin based on black and is finished in a color scheme that makes activities more enjoyable. 
It is equipped with functions that are useful for working out, including an optical heart rate sensor, a step-count accelerometer, and sensors that detect orientation, altitude/atmospheric pressure, and temperature. The GPS function can also measure running distance, speed, pace, etc. It also supports the measurement of VO2 max, which measures cardiorespiratory fitness, and can be used as an index for improving endurance when running, etc. 
Additionally, a dedicated app allows wearers to check their fitness levels and training progress, and automatically create training plans. Uses Firstbeat's library, for data analysis of VO2 max, etc., due to its good reputation in sports science, Supported by a more accurate algorithm. 
The exterior features a curved back cover to reduce discomfort to the back of the hand, a soft urethane band with excellent fit, bi-color molded buttons for superior operability, and a high-definition MIP LCD for great visibility. We sought to enhance practicality by also supporting both USB and solar charging.
