This model is a collaboration with "iSearch Japan," which is engaged in activities to promote the wonders of dolphins, whales, and nature. The black case and yellow band are a reproduction of the first model. The "iSearch Japan" logo is printed on the band, and the "Love The Sea And The Earth" symbol is engraved on the back cover. When the backlight is turned on, a whale appears. This is also the first time that biomass plastic is used in a collaborative model with Isearch Japan. The paper box is made of recycled paper. The product bag for the watch incorporates a 100% cotton drawstring bag that can be reused as a pouch.
