A special collaboration model based on a "Formless Tai Chi" theme designed by Chinese artist Chen Yingjie, who creates works using both traditional Eastern ink painting and Western street art. Chen Yingjie personally selected G-STEEL as the base model. The design theme was China's philosophy of Tai Chi. Black ion plating and original printing technology are applied to the entire watch to highlight the link between Tai Chi and the flow of time, as well as to express the concept of a cosmic system, by which the nature and order of all things change with the flow of time. Additionally, Chen Yingjie's signature engraved on the back and other details embody the concept of the flow of time, change, and the cosmic system throughout the whole G-SHOCK watch.
