Part of the 5600 series, the GWB5600SL4 digital watch from G-Shock has a unique red colorway evoking outdoor adventure. A marbled look is achieved by using Casio's mixed-color molding process, blending deep red and charcoal resin inspired by desert sand and soil. The slim 42mm case sits perfectly under sleeves, as the square G-Shock features a scratch-resistant mineral crystal display, and a black watch face. Bluetooth connectivity allows for even easier operation, as 200 meter water-resistance, shock-resistance, and a multitude of date and time functions come standard.
