Casio G-Shock GM-2100RI21-7AJR Ryo Ishikawa Golf Collaboration Watch

Product Details

The GM-2100RI21-7AJR is the second collaboration between G-Shock and professional golfer Ryo Ishikawa, released to commemorate the 40th anniversary of the Casio World Golf Open. The white resin strap and light-blue and orange dial accents reference the fairway colours of the tournament course, while the deep-blue dial itself draws direct inspiration from the green's geography. The case back is engraved with Ryo Ishikawa's signature, making this one of the few G-Shock collaborations with a personal tribute etched into the steel. Built on the GM-2100 platform, this 1:1 replica uses a Miyota-based movement for stable and accurate timekeeping, a true moveable small hand (not a painted facsimile), and the original-tooled resin strap for weight and feel identical to the retail watch. Professional QC inspection before shipping ensures every detail -- from crown action to case finishing -- matches the standard expected of a collaboration piece.
