Add a blast of color to your wrist with these Casio G-Shock GA110 Watches ($120 USD). Available in blue, green, or pink, these monotone timepieces offer a shock- and water-resistant build, an auto-calendar function, a 1/1000 second stopwatch, a daily alarm, an LED backlight, and a matching resin band. The colorways are a nice way to kick up an otherwise conservative outfit.
