The GW-2000 series is G-SHOCK's first aviation watch especially designed to meet the challenges of flying. The face is designed to minimise the reflection of bright light at high altitude. The bezel has a tachymetre with inscriptions up to Mach 1 and UTC based world time. The luminescent Arabic numerals are used for hour markers so the 12 o'clock position can be determined at a glance even under busy cockpit conditions. The mechanics of the watch are protected by G-Shock technology that shields the watch against damage and the effects of in-flight G-forces.
