The Casio G-SHOCK GD-400GB-1B2DG (often referred to as GD-400GB-1B2) is a striking timepiece that combines the rugged, street-smart aesthetic of the GD-400 series with the bold luxury of the Black and Gold collection. This model is characterized by its protective "bullbar" wires over the mineral glass, a feature popular in extreme sports to guard against direct impact to the crystal. It maintains the core G-SHOCK principles of Shock Resistance and 200-meter Water Resistance. The all-black matte resin body is accented dramatically by gold-colored details on the dial, giving it a cool, hip-hop or B-Boy inspired fashion look. It features the powerful Super Illuminator LED backlight and the practical Multi Time function, making it both highly durable and visually commanding.
