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".
Base model for this lineup is the classic GA-100 digital-analog combination model.
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.
