Official Marketing Focus from Casio

G-SHOCK announces a new lineup of heavy-duty model that is great for wear in tough environments and as street fashion items as well.
The industrial design motif of this model is created by a 10-sided bezel that resembles the shape of a nut. The bezel is secured by four screws for a tough and rugged look. Combination timekeeping is provided by analog hands along with a digital display for the ultimate in operational ease. The design of the hands and the graphic figures that appear in the digital readouts create a powerful face design that enhances readability. The band connection and all buttons have checkered surfaces that prevent slipping and contribute to operational efficiency.
