From G-SHOCK, the watch brand that is constantly setting new standards for timekeeping toughness, come new models based on the big case Tough Solar
GAS-100.

Variations on a basic black design are created by three different bezels. The GAS-100 comes with a stainless steel bezel for a standard design that goes well with a wide range of fashion styles, while the GAS-100G has a stainless steel bezel with a gold ion-plated finish for touch of distinctive beauty. The GAS-100B has a black aluminum bezel for a cool design.
A CASIO original molding process is used to produce deposition coated hour markers that combine with the metal bezels to create a look of elegance.
