There are some things that you know are fundamentally bad for you, but you can’t resist consuming them. Coke (the soft drink) is one such commodity, and especially during the summer season, it has become more of a necessity than an indulgence. The brand itself has been around for 140 years and has built itself into something that virtually everyone recognizes, from its logos and visual cues to its timeless ad campaigns. It has become a cultural artifact for well over a century, transcending beverage culture to become one of the most iconic brands in history.
To celebrate this milestone, Coca-Cola has partnered with another recognizable global brand, G-Shock, to create a limited-edition collaboration. The GA-2100CC-3A is the first-ever Coca-Cola watch built on the analog-digital GA-2100 base, which has its own massive cult following in the watch community. Enthusiasts affectionately nicknamed the GA-2100 the “CasiOak,” a nod to its resemblance to the luxury Audemars Piguet Royal Oak, making it one of the most talked-about G-Shock models of the modern era.
Designer: G-Shock x Coca-Cola
You would think that a Coca-Cola collaboration would have red and white splashed all over, but G-Shock took a more refined, classic approach. Instead of leaning into the brand’s signature bold palette, the design focuses on a translucent green bio-based resin that is directly reminiscent of Coca-Cola’s iconic vintage contour glass bottle. You do get minimalist splashes of red throughout the design, as it is of course the color most associated with the brand, but it’s tasteful rather than overwhelming. Instead of just slapping the logo on this wearable, you get smart design easter eggs that will delight the most die-hard of Coke fans.
Both the bezel and band come in the aforementioned translucent green, with the dial receiving Coca-Cola-toned hues as well as printed graphics evoking the iconic bubbles from the soft drink’s fizz. At the 9 o’clock position, the date indicator hand is shaped like the brand’s beloved fluted glass bottle. That same bottle motif is carried over into the band loop as well, keeping the design cohesive and intentional. Flip the watch over and you’ll find the case back engraved with a bottle cap-inspired design, a subtle but brilliant finishing touch. The entire watch also arrives in exclusive special-edition packaging specifically created to commemorate the brand’s 140th anniversary, making it a complete collector’s package from the moment you open the box.
It’s also worth noting that the use of bio-based resin is not just a stylistic choice. It reflects a growing commitment to more sustainable materials in watchmaking. The GA-2100 series adopted bio-based resin in 2024, and it carries forward seamlessly into this collaboration, giving the watch a modern, eco-conscious edge that feels right at home in 2026.
In terms of technical specifications, you still get all the great hallmarks of the GA-2100 base, which has made it one of the more popular G-Shock models. It is shock resistant as well as water resistant for up to 200 meters. It comes equipped with the usual functions including a timer, stopwatch, and Double LED light, with an approximate battery life of 3 years. The case measures 48.5 × 45.4 × 11.8 mm and weighs in at 51g, slim and lightweight for a G-Shock, which has always been a big part of the GA-2100’s appeal.
The GA-2100CC-3A is priced at ¥27,500 JPY (approximately $175 USD) and is set to release in May 2026 via the Casio webstore. Given that this is a limited-edition piece tied to a once-in-a-generation anniversary, it’s the kind of watch that won’t sit on shelves for long.
Whether you’re a G-Shock collector, a Coca-Cola memorabilia enthusiast, or simply someone who appreciates thoughtful design collaborations, the GA-2100CC-3A checks every box. It’s nostalgic yet modern, playful yet polished, and honestly, much like the drink it celebrates, it’s the kind of thing you didn’t know you needed until it’s right in front of you.
