From G-SHOCK, which continues to evolve in pursuit of toughness, we are introducing a series that focuses on the brand's colors of black and red.

The bezel, band, and dial are black, and the LCD on the face is a new high-saturation color LCD (with improved visibility),
making this a highly designed series.

When the light is on, the text on the digital display lights up to ensure visibility.

This model has a cool black base.
