Casio G-Shock G-Squad Watch GMDB300-1D

The ideal companion for your active everyday — a sports-oriented G-SHOCK with step tracker delivers handy support for your healthy, active lifestyle.

Start walking and the motion-sensing accelerometer counts your steps automatically. The watch displays total daily steps as well as progress toward goals. Tracked data sent to a dedicated app helps you easily manage life log data.

Indulge in natural hues that add a touch of colour to daily life. Matte textures pair with light accent colours to produce colour block designs, and the dial features a sportswear fabric pattern to perfectly accent your effortless casual style.

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