G-SHOCK, the toughness watch that has continued to evolve in pursuit of insatiable strength since its release in 1983, is introducing the HIDDEN GLOW SERIES, which expresses human potential with luminous parts that glow in the dark.

The watch features a white and blue color scheme that evokes the image of the summer sea, and a blue phosphorescent face that expresses the fantastic light emitted by bioluminescent insects, expressing the beach scene that shows different expressions during the day and at night.

Each model features a distinctive dial design, enhancing its individuality with color and light.

In addition, the main resin parts of the bezel and band of the GA-2100HDS are made from biomass plastic, which is expected to contribute to reducing the burden on the environment.

A cool design that will accentuate your casual and work style.
