Introducing a new lineup of slim G-STEEL GSTB400 models with new, improved designs made possible by a thin module and carbon core guard structure. The standard model in this lineup, the GSTB400-1A sports a silver color face and resin band. The GSTB400 is made possible by even further miniaturization of its parts and thinning of its modules without sacrificing any Bluetooth or solar function. Power consumption has also been significantly reduced.

New G-Shock G Steel Watch Is the Slimmest Yet

GST-B400-1A - G-SHOCK MAG.

An ultra-thin module encased in carbon fiber makes for a stylish G-STEEL timepiece with the slimmest profile yet. Strong, yet lightweight, the carbon core guard structure absorbs external shocks and retains Bluetooth connectivity and solar power functionality even with smaller components and a thinner module. Measuring just 12.9mm from the back of the case to the top of the bezel, the GST-B400 is over a millimeter thinner than its predecessor.
