G-SHOCK and Coca-Cola come together on the GA2100CC-3A, a limited collaboration built around Coca-Cola’s 140th anniversary. The watch uses the GA-2100 platform, one of G-SHOCK’s most recognizable modern shapes, and pulls the design through the visual language of Coca-Cola’s classic contour bottle.
The GA-2100 already has a strong base for a collaboration like this. It is slim for a G-SHOCK, built with the brand’s octagonal case shape, and carries the analog-digital layout that has made the 2100 series one of the most popular lines in the G-SHOCK catalog. The Coca-Cola version keeps that shape intact, then shifts the surface details toward bottle glass, soda fizz, and vintage Coke branding.
The bezel and band are done in a translucent green tone inspired by the Coca-Cola contour bottle. That bottle has been part of the brand’s identity for more than a century, and the watch leans into that look instead of defaulting to the obvious red-and-white Coca-Cola treatment. The green gives the GA-2100 a different kind of Coca-Cola reference, closer to glass, vending machines, bottle caps, and the older pieces of the brand’s history.
Casio adds more bottle details throughout the watch. The day indicator hand at 9 o’clock uses a fluted bottle shape, and the band loop carries the same bottle motif. The dial brings in Coca-Cola-toned hues with printed graphics that reference carbonation bubbles, giving the face more movement while keeping the display readable. Red accents sit at the tips of the hour markers, tying the green case back to the familiar Coca-Cola palette.
