New Casio G-Shock GA2100 modular glow-in-the-dark collab watch unveiled

Adding to the long streak of April and May's collab watches, Casio G-Shock has just announced a new limited-edition collaboration with Crocs, set to release on May 27. The drop includes a GA2100CROCS25-7 watch bundled with a matching pair of Echo Wave clogs. Both are designed with a shared marbled pattern, and the bundle offers a few firsts for both brands - including modular integration between the watch and the footwear.

This GA-2100 model, which follows the slim and lightweight "CasiOak" format, features glow-in-the-dark accents and a custom Crocs logo printed directly on the dial. Its case back also carries a special engraved design unique to the release. The removable strap carries a marbled finish that matches the lining of the Echo Wave clogs, and the box itself is designed with the same color theme across all components.

Function-wise, the watch still includes the essentials: 200m water resistance, world time for 48 cities, shock protection, stopwatch, countdown timer, 5 daily alarms, and a double LED backlight. The modular band system allows the watch to be removed and clipped directly into the Crocs' rivet system - the same space typically used for Jibbitz charms (attachments for crocs).

This makes it one of the few G-Shock watches designed to be worn either on the wrist or integrated directly into footwear. The bundle will be sold through select wholesale partners and on crocs.com. Pricing details are yet to be revealed, and there’s no confirmation on whether the watch will be available separately.
