G-SHOCK, a toughness watch that has continued to evolve in pursuit of insatiable strength since its release in 1983, has released the fourth signature model of professional golfer Ryo Ishikawa, who belongs to Casio Computer Co., Ltd. and holds the record for being the youngest gold medal winner in Japan. To do
The base model is the popular GM-2100, which features an octagonal metal bezel.
The color scheme and design are different from the normally released inline model.
The bezel is a metal cover, and the dial is made of green inspired by golf (with a golf ball dimple pattern as a watermark).
The band is made of resin and has a comfortable finish.
Additionally, the back cover is engraved with Ishikawa's handwritten signature and the message "GO FOR THE TOP", which is a message to aim for heights.
Inspired by G-SHOCK and Ishikawa, who will continue to aim for great heights, we have created a cool and detailed design that can be used for both lifestyle and golf play.
