Three new color variations of the Tough Solar GAS-100 add new flavor to this case design. 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.
