Casio G-Shock has collaborated with NBA professional basketball player Rui Hachimura to create this new signature G-Steel model. Representing Hachimura's jersey number, the hour marker at 8 o'clock is red. The Japanese word for 8 is hachi, which is also part of Hachimura's name. The button pipe of the Bluetooth® connection button at 8 o'clock and the indicator disk are also done in red. The gold ion-plating of the bezel and case parts along with a Rui Hachimura logo on the band ring and package create a bold, sporty look befitting of a special model such as this. A simple operation connects with the G-Shock Connected phone app for quick and easy time adjustments, simplified timer and other function settings, phone number searches and more. A high-brightness LED light enables easy reading of the display, even in the dark. This new tough, sporty and fashionable timepiece captures the essence of everything that Rui Hachimura represents.
