G Shock G Steel Duo GSTB400BD-1A2

The G-SHOCK G-STEEL GST-B400 series combines style and durability with its ultra-thin module encased in carbon fiber, delivering the slimmest profile yet. The carbon core guard structure ensures strength and lightness, absorbing external shocks while maintaining Bluetooth connectivity and solar power functionality. Measuring a mere 12.9mm from the case's back to the top of the bezel, it's over a millimeter thinner than its predecessor. The dial showcases a bold blue vapor deposition finish with a black ion-plated bezel and band, while the top and middle bezels feature various textured finishes for a sophisticated look from every angle.
