A new wave of excitement is building for fans of cross‑brand collaborations, as a fresh leak suggests Casio’s G‑Shock and beverage giant Coca‑Cola are plotting another limited‑edition release for 2026. This time, the partnership appears to be targeting the wildly popular GA‑2100 series—affectionately known as the “CasiOak”—with a design that harks back to Coke’s iconic green glass bottles.
The Leak: Model Number Points to a Green‑Bottle Theme
The rumor originates from a recent Instagram post by the well‑known Casio leaker account @geesgshock. The post claims that an internal model number, GA‑2100CC‑3A, has been confirmed for a 2026 Coca‑Cola collaboration. The “CC” suffix is the key clue here, as it directly mirrors the coding used for the previous Coca‑Cola G‑Shock models.

This naming convention strongly suggests the watch will follow the aesthetic path of the DW6900CC23‑3, released in 2023. That model featured a semi‑transparent green resin case and band, a direct nod to the hue of vintage Coca‑Cola glass bottles. Based on this precedent, watch enthusiasts and collectors are speculating that the GA‑2100CC‑3A will sport a similar, predominantly green octagonal case, accented with classic white Coca‑Cola logo branding and pops of red in the details to complete the recognizable soda palette.
A Brief History of the Thirst‑Quenching Collab
This won’t be the first time these two iconic brands have joined forces. Casio and Coca‑Cola first partnered in 2023 on two successful limited editions:
- The DW5600CC23‑4, a bold, solid Coke‑red version of the classic square DW5600.
- The DW6900CC23‑3, the aforementioned translucent green “glass bottle” iteration of the round‑faced DW6900.
Both models came with co‑branded packaging and focused primarily on unique colorways and branding rather than introducing new technical features. They stayed very close to the core specifications of their base models.

Given this pattern, it’s highly likely that a GA‑2100 Coca‑Cola watch would be a similar proposition: the beloved, rugged, and affordable CasiOak platform dressed up in a special, collectible design. The GA‑2100 is renowned for its lightweight, shock‑resistant construction and classic analog‑digital display, making it a perfect canvas for a vibrant collaboration.
What We Still Don’t Know
As with any early leak, caution is advised. The leaker has only provided the model number and the 2026 collaboration claim. There is no official listing on Casio’s website or in their collaboration archive yet.
Critical details such as the official release date, specific markets, production numbers, and final pricing remain unconfirmed. Casio has not issued any statement regarding the rumor, so the design expectations, while logical, should be taken with a grain of salt until an official announcement is made.
For those inspired by the prospect of a CasiOak and looking for a reliable daily wearer, the standard model is a great place to start.

The potential for a G‑Shock GA‑2100 Coca‑Cola edition in 2026 is already generating significant buzz. If the rumors hold, it would marry the streetwise appeal of the CasiOak with the timeless, globally recognized branding of Coca‑Cola, likely creating another instant hit for collectors and casual fans alike. Stay tuned for official updates as we get closer to 2026.
