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.

The Ryo Ishikawa collab G-Shock is a cool limited release rep. The green and white golf-themed colorway on the GM-2100 octagon form is subtle and well executed.
Great conversation starter at the golf course. The collab details on the dial and strap are accurate to the reference. Comfortable and light for active wear.
Octagon case in this collab colorway is sharp. Resin band is soft right out of the box. All G-Shock functions work. Arrived in 11 days in original-style packaging.
Nice unique collab piece. The golf motif accents on the dial are crisp and the color coordination between case and strap is on point. Very wearable as a daily driver.
Q: What is special about the Ryo Ishikawa collaboration design?
A: The collab features golf-inspired color accents and co-branded dial details -- a more refined, athletic aesthetic compared to standard GM-2100 colorways.
Q: Is the GM-2100 octagon a resin or metal-bezeled case?
A: The GM-2100 series uses a metal bezel over a resin case body -- giving it a more premium look than full-resin G-Shocks at a lighter weight than full metal.
Q: Is this suitable as an everyday sport watch?
A: Absolutely -- the G-Shock platform is built for shock, vibration, and general abuse. The resin body and metal bezel combination is very resilient for active use.
