G-SHOCK, the tough watch that has continued to evolve in pursuit of ever-increasing strength since its launch in 1983, is pleased to announce the fifth signature model from professional golfer Ryo Ishikawa, who is affiliated with CASIO.

The base model is the GA-2100 with an octagonal bezel and a slim case that won't get in the way during your golf swing.

The dial features a calm blue that evokes fighting spirit, the overall color scheme is white, which represents purity and determination, and the orange accent color represents hope, making it easy to coordinate with any golf wear.

In addition, the skeleton dial creates an impressive design that has never been seen before.

Ryo Ishikawa's signature is engraved on the case back and at the 12 o'clock position, and the watch comes with a special package that includes a trading card, making it a special edition.
