Casio G-Shock GA-2100 Lineup Carbon Core Guard Structure Bluetooth¶ô¶÷ Solar Watch GAB2100FC-7A GA-B2100FC-7A

Who says you can’t be playful and tough? Introducing the rugged G-SHOCK dressed up with splashes of colorful accents — ready to party and play.

The watch is based on the GA-B2100, which maintains the distinctive octagonal form of the GA-2100 and has handy functions like Smartphone Link and Tough Solar charging. It also employs the Carbon Core Guard structure to preserve a similar fit on the wrist as the original model.

Monotone base colors — black, white, and green that easily coordinate with your favorite fashions — are decorated with bright red, blue, yellow, and green accenting on the bezel inlay sections, dial components, index markings, and the indicator of the inset dial at the 9 o’clock position. The result is a special treat of minimalist design splashed with a stream of confetti-like color.

A great way to celebrate in playful casual style — whether hanging out with friends or rocking it at an outdoor concert or festival.
