A watch that looks like it fell out of a 1960s airport terminal is about to drop, and it is built on one of the most recognisable G-Shock shells around. C2H4, the Los Angeles based streetwear label founded by designer Yixi Chen, has teamed up with Casio G-Shock for the second time, and the result is a translucent, silver-dialled reinterpretation of the GA-2100, the watch collectors call the CasiOak.
The collaboration goes live on July 17, 2026 at 9 AM PST, and it is already generating buzz among watch and streetwear collectors alike. Here is everything worth knowing about the design, the price, and why buyers in India will need a workaround.
What Is the C2H4 x G-Shock VOL.2
The new watch is officially called the GA-2100C2H426-8A, and it is the second joint release between C2H4 and G-Shock, following a GM-5600 collaboration that launched in 2025. Where that first watch used a mirror finished metal frame, VOL.2 pushes transparency across the entire shell.
The design leans on a concept C2H4 calls Space Age, a mid-century aesthetic built around streamlined forms, unusual materials, and a stripped back colour palette. The brand sums up the idea in one line: “the future of design lies in the past.”
CasiOak is the nickname the watch community gave the GA-2100 after its octagonal bezel drew comparisons to the Audemars Piguet Royal Oak. It has since become one of the most modified and collaborated-on G-Shock shells in the lineup.
Design and Build
The VOL.2 keeps the GA-2100’s slim Carbon Core Guard structure but changes almost everything about how it looks.
- A translucent, smoky grey resin bezel and strap replace the usual solid colourway
- The dial gets a brushed silver finish through vapor deposition, a process that bonds a thin metallic layer onto the surface instead of printing colour on top, so the shine looks built into the dial rather than coated on it
- The digital display uses a blue tinted reverse LCD instead of the standard black background
- The case back is engraved with the Theme Building, the Space Age era structure at Los Angeles International Airport that anchors the entire design story
None of the toughness is traded away for the new look. The watch retains G-Shock’s signature shock resistance along with 200 metre water resistance, and it carries the full GA-2100 feature set: world time across 31 zones, a 1/100 second stopwatch, a countdown timer, five daily alarms, a full auto calendar that runs accurately through 2099, and a double LED Super Illuminator for low light visibility.
The packaging is arguably as talked about as the watch itself. It ships in a custom metallic silver and teal capsule case styled after 1960s industrial design, specifically the Panasonic TR-005 “Orbitel” television, continuing the presentation language C2H4 introduced with its first G-Shock collaboration.

Will It Be Available in India
This is where collectors in India need to temper expectations. The C2H4 x G-Shock VOL.2 is a direct-to-consumer exclusive, sold only through C2H4’s own website at launch. It is not part of Casio’s standard retail rollout, and there is no confirmation of Indian pricing, shipping, or allocation at this stage. Even in markets like Australia, coverage of the launch notes the same gap: no local pricing or stock confirmed.
That leaves two realistic paths for buyers here. The first is ordering directly from C2H4 once the drop goes live and factoring in international shipping plus customs duty on import. The second is importing through a reseller once resale listings appear, though pricing on those tends to run well above the USD 245 retail figure once fashion resale platforms get involved.
For anyone who wants the CasiOak silhouette without the import hassle, the standard GA-2100 lineup remains one of the easiest G-Shock models to buy in India right now, and it shares the same case, water resistance, and toughness as the base watch this collaboration is built on.

If that specific colourway is out of stock by the time you check, browsing the wider GA-2100 range is the next best option.
Why This Collaboration Matters
G-Shock’s 2100 series has seen no shortage of colourways over the years, but most of them are palette swaps rather than watches built around a single idea from the ground up. The C2H4 collaboration is one of the few that commits to a full design language, from the dial finish down to the packaging, and it follows closely behind other high profile GA-2100 team-ups this year, including the Coca-Cola edition that sold out shortly after release.
For streetwear and watch collectors, VOL.2 is less about telling time and more about owning a specific design statement. If you already picked up the GM-5600 version from 2025, this is a companion piece rather than a repeat, same Space Age concept, different silhouette, different finish. If you are coming to the collaboration fresh, the slimmer GA-2100 base makes this the easier of the two watches to actually wear day to day.
