The Coca-Cola x G-SHOCK Collaboration Channels the Classic Contour Bottle

Summary

• The new collaborative timepiece utilizes G-SHOCK’s popular 2100 series as its foundational base
• Construction highlights include a translucent green bio-based resin and Carbon Core Guard structure
• Subtle dial and case back engravings directly reference iconic Coca-Cola bottle elements

G-SHOCK is celebrating 140 years of Coca-Cola with the new GA-2100CC-3A timepiece. Built upon the beloved octagonal framework of the GA-2100 series, this latest collaborative model strips back the expected bright red branding in favor of a specialized material execution inspired by the classic Coca-Cola contour glass bottle.

Constructed with a meticulous focus on tactile and visual details, the timepiece features a streamlined case and bezel cast in translucent green bio-based resin. This specific color application directly mimics the distinctive tint of vintage Coca-Cola glass bottles. The material choice extends to the matching bio-based resin band, ensuring the timepiece maintains G-SHOCK‘s signature durability while utilizing an eco-conscious manufacturing approach. The underlying architecture utilizes Casio’s proven Carbon Core Guard structure, keeping the watch lightweight at just 51 grams while offering rigorous shock and 200-meter water resistance.

Looking at the dial, the design layers functional watch mechanics with nuanced thematic nods. The textured brown surface utilizes a printed pattern meant to evoke carbonation bubbles, contrasting against prominent rose-gold hour markers. A custom bottle graphic serves as the day-of-week indicator at the 9 o’clock position, incorporating the fluted motif of the contour bottle. This same fluted texturing is mirrored on the bio-resin band loop, while the stainless steel case back is finished with an exclusive bottle-cap engraving. Dual LED illumination and a robust three-year battery life complete the technical package.

To understand the weight of any new 2100 release, you have to look back at the seismic shift the model caused upon its debut in 2019. Originally launched as a quiet addition to the G-SHOCK catalog, the GA-2100’s slim profile and distinct octagonal bezel instantly drew comparisons to the legendary Audemars Piguet Royal Oak. The community quickly dubbed it the “CasiOak,” sparking a massive wave of third-party metal mod kits and aftermarket customization that dominated watch coverage. G-SHOCK wisely leaned into the hype, eventually answering the market’s call with official metal-clad versions (the GM-2100 series) and high-end full-metal iterations that successfully bridged the gap between accessible streetwear accessories and luxury horology aesthetics.

Check out the watch above. The Coca-Cola x G-SHOCK GA-2100CC-3A is available for ¥27,500 JPY (approx. $175 USD) in May 2026 via the Casio webstore.
