A heavy-duty model that can be used in tough environments as well as for street fashion. The nut-like 10-sided bezel is fastened with screws to express the industrial design motif, and is finished in a rugged, tough, and straightforward design. The use of analog hands with a digital display also enhances usability. High visibility is achieved, even in the powerful face, by inserting graphics on the hands and dial. Additionally, the lug ends of the band and all the function buttons, including the front button, are engraved with non-slip checkering for excellent operability. Features skeleton-type coloring based around gray. Based on the rugged, tough form of the GA-900, this skeleton series model features chic coloring making it suitable as a fashion item.
