C2H4® to release second G-Shock collaboration on July 17: GA-2100 The Space Age Edition
July 12, 2026
Following its GM-5600 collaboration in 2025, L.A. fashion label C2H4® is releasing its second limited edition G-Shock on July 17, 2026 (9:00 a.m. PST). Like the previous watch, this G-Shock GA-2100 model is billed as “The Space Age Edition” and is inspired by the Theme Building at the Los Angeles International Airport.
The watch features retro-futuristic style with a translucent gray bezel and band combined with silver metallic finishes on the dial, indices, and hands. A C2H4® logo is printed above the Casio logo on the dial, and the case back features an engraving of the Theme Building. Like the 2025 release, the watch comes with a retro capsule case inspired by the 1970 ATC Genie Telephone, but with silver and teal colors this time. (The watch is mislabeled as a GM-2100 in one of the promotional images, but it is clearly a GA-2100.)
Founded in 2014 by designer Yixi Chen, C2H4® is recognized in China where the previous release (GM-5600C2H424-8) was released online by Casio.
The GA-2100 collab will be available on July 17 (9 a.m. PST) at c2h4losangeles.com. (C2H4® offers international shipping.)
