Casio G-Shock Men's 51mm GA1100-2A Watch - Red/Blue

One of the latest additions to the GRAVITYMASTER series, this model has been conceived and developed as an aviation timepiece. It features a new type of world time function that's designed with international pilots in mind. In addition to the time in your current location, a second time can be indicated by the dial at 9 o'clock. Other pilot-friendly functions include a large button that can be used to trigger a 60-second continuous bearing or temperature sensor reading with a single press. A high-luminosity LED display light enables easy reading even in the dark. A pilot or not; this performance watch is as versatile and functional as its good looks.
