Singapore based visual artist JAHAN LOH has selected five popular G-SHOCK models and specially designed them based on the theme of the "Five Generals" from Chinese history and the Chinese philosophy of the "Five Elements and Five Constants". The "Five Elements" refers to the five elements that make up all things: water, wood, metal, earth, and fire, and the "Five Changed Things" refers to the five paths that people should always follow: humanity, righteousness, propriety, wisdom, and faith. These concepts are superimposed on the images of the five generals: Ma Chao, Zhao Yun, Guan Yu, Zhang Fei, and Huang Zhong. Each model has its own band. The band of each model is printed with the textures of "Water, Wood, Metal, Earth, and Fire". The back of the watch is engraved with the words "Jin, Yi, Rei, Ji, Shin". The packaging has also been specially designed and finished to match the special model. This is a new collaboration model that embodies the philosophy and history of China from G-Shock, a toughness watch that fuses with various cultures around the world and pursues design evolution.
