Casio G-Shock CLASSIC GA-2100LXB-1AER

The LUXE BLACK line reinterprets the iconic 2100 series through an essential, modern, and sophisticated design. The matte black dial, characterized by a fine texture that reduces reflections, enhances the slender hour and minute hands and indices with silver vapor deposition treatment, creating refined metallic contrasts.

The black resin bezel and band complete a minimalist and timeless aesthetic, maintaining the iconic G-SHOCK toughness.
