New York City bike and apparel retailer Chari & Co is teaming up with Casio to release the limited G-Shock GA500K-3A. The collaboration watch featuring black and olive colors forming triangular shapes is inspired by the three main components of a bicycle (the top tube, seat tube, and down tube), a design motif previously seen on Chari & Co racing apparel. The watch also has a Chari & Co logo on the face and a custom engraved case back, and includes a co-branded box and tin.


I was assigned to be art director and designer to create special collaboration model G-SHOCK GA500K watch, and also create bike jersey and merchandises.

The main triangle of a bicycle frame is made up of a top tube, seat tube, and down tube. Together, thes three tubes are responsible for determining th strength and stiffness of a bicycle The geometry of these three tubes, which should match the needs and dimensions of each rider, can significantly affect one’s time on the bike.
