This G-STEEL variation is a new signature model that was designed under the supervision of NBA professional basketball player Rui Hachimura.
The hour marker at 8 o’clock is red, representing Hachimura’s jersey number. Also, 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 IP (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.
But the great-looking design of this model is only half of the story. 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.
