Casio G-Shock for Ladies' Bio-Based Watch GMAP2100ST-4A GMA-P2100ST-4A

Silky smooth with pearly luster-a soft, subtle, and sophisticated timepiece.

Pearlescent polarized coatings with a matte finish are applied to the bezel and band. The matte metallic color of the dial adds a beautiful luster for a simple, minimalist design with a touch of extra shine.

Key resin components used in the bezel and band are made with bio-based resin. Produced using renewable organic resources, this material is expected to help reduce environmental impact.
