High visibility Casio G-Shock GA-2100 watch launching soon

A new Casio G-Shock x Ron Herman watch has been announced in Japan. This 2026 model, based on the GA-B2100, is the latest in a string of collaboration watches from the Japanese watchmaker and the Californian lifestyle brand.

The upcoming Casio G-Shock x Ron Herman GA-B2100 watch has a high-contrast design. It features a matte black resin casing and strap, with matte white accents like the chapter ring, indexes and analog hands. This model has a 48.5 x 45.4 x 11.9 mm (~1.91 x 1.79 x 0.47 inches) casing, with an octagonal bezel. 

Features of the hybrid GA-B2100 include the Carbon Core Guard structure, 200 m water resistance and Tough Solar charging. Users can choose from a range of world time zones, and there are on-watch tools like a stopwatch, alarms and a timer. Plus, Bluetooth connectivity brings further functions, like auto time adjustments, when paired to a smartphone.

In Japan, the limited edition Casio G-Shock x Ron Herman GA-B2100 will retail for ¥36,300 (~$228) at launch on May 9th. These Ron Herman collaborations tend to be exclusive to the Japanese market. However, you can buy other versions of the G-Shock GA-B2100, such as the GA-B2100-1, in the US and European countries like Germany (curr. €149 at Casio Store).
