Casio G-Shock Two-Tone Utility Watch GA100TU-1A3

Stylish, Practical, Reliable: The GA100TU-1A3 Utility Watch

To be practical is commonly thought a sacrifice of style, functionality over form. G-SHOCK shirks the common thinking and delivers the stylish two-tone G-SHOCK GA100TU-1A3 utility watch, a tough and beautiful addition to the Two-Toned Utility collection. The popular GA100 series is one of G-SHOCK’s large-dial watches, and the large watch face not only makes for an easy read but delivers on durability. The modern dial design forefronts two upper dials used to display and measure speed, a useful and integral part of the stopwatch mode. Teal and yellow accents enliven the dial and hands, while the multilayer dial and raised indices create a bold 3D watch face. The G-SHOCK GA100 style crafts the clear sense that beauty, performance, and utility can go hand in hand.

Smart combos of colour abound and augment the practical build. The olive-green watchband is crafted of durable resin, granting the same durability in materials enjoyed by the matte-black resin case and bezel. G-SHOCK-famous, shock-resistant construction is coupled with 200-meter water resistance, but this GA100 two-tone watch goes a step further: magnetic resistance makes the watch less susceptible to magnetic fields. Utility and style underscore a craftsmanship that is exclusively G-SHOCK.

Smart style shaking hands with reliability and comfort for everyday work: that’s the Two-Toned Utility collection.
