- G-Shock Duo Nishikigoi GA-100JK-4A
This series is designed in the image of Nishikigoi, a world-renowned variety of carp that are often called "living jewels" and "swimming art pieces".
The white, red, and black motif of the GA-100JK is based on the white, scarlet, and black Taisho Sanshoku koi.
The white face also features red and black accents, creating the Taisho Sanshoku image. The hand of the inset dial of the GA-100JK is designed in the image of a Nishikigoi.
The band ring of this watch features an illustration of a Nishikigoi to emphasize the connection between this model and the Nishikigoi.
The package design and special cards included with this model were designed by the independent BlackEyePatch label of Tokyo.
This G-SHOCK model is made in Japan and this reflects the quality and attention to detail for which Japan is famous.
