The Casio Limited Edition GA-110SR-1AER digital watch has a great, simple design. The watch has a carbon fiber reinforced thin and black resin case, 45.4 mm wide and 11.8 mm thick, and weighs 51 grams. The Casio Limited Edition GA-110SR-1AER watch body uses Carbon Core Guard construction, which provides excellent impact resistance by exploiting the properties of carbon fibers (impact resistance, rigidity and resistance to degradation), which are also used in aircraft fuselage parts. The wristband is made of polyurethane, which is very durable and comfortable to the touch. The iridescent color on the dial, the first-ever G-SHOCK with full-surface gradated crystal finish evokes reflected sunlight giving this watch a unique look.
