Indulge your love of all things vintage with a monochromatic take on a time-honored Casio watch. Paying homage to the F-100, the first Casio watch designed with a resin case, the A-100 line commemorates the iconic four front buttons, adding vintage-style metallic components for an updated reboot of a true classic. Retro in style but packed with contemporary functionality, this timepiece boasts a stopwatch, calendar, water resistance for daily use, and of course an LED light for an easy read in any lighting.
