Casio’s Coca-Cola collaboration is the GA-2100CC-3A, a GA-2100-series analog-digital G-SHOCK that Casio presents as a 140th-anniversary watch for Coca-Cola. Its green palette and bottle-inspired details distinguish it from a standard CasiOak, but Casio’s regional pages do not establish one worldwide release date, price, or current stock level.
What is the Coca-Cola CasiOak?
The GA-2100CC-3A is built on the GA-2100 platform, the octagonal-bezel G-SHOCK design often nicknamed the CasiOak. Casio describes the collaboration as marking Coca-Cola’s 140th anniversary in 2026; its product copy says the company was founded in Atlanta in 1886. Those are Casio’s anniversary framing and historical reference, respectively. Casio India’s product page and G-SHOCK Europe’s collaboration page identify the model and its theme.
How the design references Coca-Cola
The watch translates Coca-Cola’s contour bottle into details across the case, strap, and dial rather than relying only on a logo. Casio describes the bezel and band as drawing their colors from the bottle. The day indicator at 9 o’clock and the band loop use a fluted motif inspired by the bottle’s shape; printed dial graphics evoke bubbles in a fizzy drink. A bottle-cap-inspired engraving appears on the case back, and the watch comes in special anniversary collaboration packaging. G-SHOCK Europe and Casio India describe these design elements.

When does the Coca-Cola G-SHOCK come out, and how much does it cost?
G-SHOCK Philippines’ announcement page is marked “Published 24 April 2026.” That is the publication date of the Philippines page, not confirmation of a worldwide on-sale date. The official regional pages provide product and purchase or notification pathways, but do not establish a universal price or current inventory across countries. Check the relevant Casio site or an authorized local retailer for availability and price in your market. Philippines announcement · Europe collaboration page · India product page

The GA-2100CC-3A is not one of the older Coca-Cola collaborations. Casio’s US collection page lists the red-themed DW5600CC23-4 and the green-glass-bottle-inspired DW6900CC23-3; that page labels the latter discontinued. These are historical reference points, not evidence about the new model’s availability or status. G-SHOCK US Coca-Cola collection
