※ We are very sorry, but we do not ship to Okinawa, Hokkaido, and remote islands. This is the "First Generation G-SHOCK Revival Model," which symbolizes the evolution and inheritance of the brand. The design embodies the will and expectations for the future that were put into the original model, and it has been revived as much as possible with the technology of the current G-SHOCK. The case is made of stainless steel, just like the original, and the band also reproduces the original model's length, shape, and dimple positions. On the other hand, the bezel and band material use biomass plastic, and the case size has been increased from the original model's 41.6mm to a modern 42.3mm. The face and back cover designs also faithfully reproduce the original model, and the design is inherited down to the smallest details.
