The Casio G-Shock x Coca-Cola collaboration is the GA-2100CC-3A, a GA-2100-series watch with a transparent green case and band inspired by Coca-Cola’s contour bottle. Casio says it was created to mark Coca-Cola’s 140th anniversary. A Casio-authorized Hong Kong listing gives May 2026 as its launch date, but availability and pricing vary by region.
What is the model number of the Coca-Cola G-Shock?
The collaboration model is the GA-2100CC-3A. Casio identifies it as a G-Shock based on the GA-2100 series. The US regional product page also identifies the collaboration as GA2100CC-3A, without a hyphen between “GA” and “2100.” Check the full reference and suffix when comparing listings, since the exact model designation is the clearest way to distinguish this watch from other GA-2100 variants.
Casio describes the watch as created to celebrate Coca-Cola’s 140th anniversary. That is the stated commemorative premise; the product information reviewed does not specify a production quantity or establish that the run is numbered.
CASIO Europe’s GA-2100CC-3A product page documents the design and specifications. CASIO US also has a regional product page.

What makes the Coca-Cola edition different in design?
The most noticeable feature is its transparent green case and band, which Casio says draw inspiration from the Coca-Cola contour bottle. The bottle reference carries through into smaller details rather than stopping at the color.
- The date indicator and strap loop use fluted motifs inspired by the bottle.
- Printed details on the dial evoke bubbles and fizz.
- The case back has a bottle-cap-inspired engraving.
- Casio describes exclusive collaboration packaging. The European product page depicts a red package inspired by a retro soda machine.
The design cues and packaging are manufacturer-described features, not evidence that the watch is numbered or that every regional box presentation is identical.
Rank #2
- {"bullet_point1":"clip-on"}
- The rugged watch's 45.4mm case is expertly crafted from fine resin mixed with carbon fiber, an innovative composition that is lighter and more durable than resin
- The smooth black dial features an analog-digital display and double LED light feature, for easy visibility in the dark

When did the Coca-Cola G-Shock come out?
The Casio-authorized Hong Kong Casio Online Flagship listing operated by Jebsen Consumer displays May 2026 as the product launch date. That date describes the Hong Kong listing and does not establish the launch date in every country. The listing showed the watch out of stock in Hong Kong when accessed on October 7, 2026.
Check the Hong Kong listing for its current local stock display. Stock can change, and a listing for one market does not establish availability elsewhere.

Price, stock and what “limited edition” means here
The official and authorized pages cited here do not establish one worldwide retail price, a total production quantity, or current US stock. They identify the collaboration and provide product information, but do not substantiate a numbered run or a specific number of watches made. Treat “limited edition” as a description of the collaboration, not as confirmation of a production limit unless a local Casio or authorized-retailer listing states one.
For a purchase, check the listing in your country for current price and stock. Confirm that it names GA-2100CC-3A (or the US page’s GA2100CC-3A designation), and verify the seller, condition, included collaboration packaging and regional warranty. Regional price and stock information should be treated as time-sensitive.

How to compare it with other GA-2100 watches
The documented distinction is the Coca-Cola-themed design and packaging; the sources do not establish a performance advantage over other GA-2100 watches. Compare the models against what matters to you rather than assuming the collaboration changes the underlying everyday-use proposition.
