Casio G-Shock Master of G Gravitymaster Watch GA1100-1A

Introducing the latest new additions to the GRAVITYMASTER Series of the watch that is conceived and developed as aviation timepiece.

This new model features a new type of World Time function that is designed with international pilots in mind. In addition to the time in your current location, which is indicated by wide hour and minute hands, a second time can be indicated by the dial at 9 o’clock.

Other pilot-friendly functions include a large button at 9 o’clock that can be used to trigger a 60-second continuous bearing or temperature sensor reading with a single press. Also, a high-luminosity LED display light enables reading of display information even in the dark.

All of this and much more makes this new GRAVITYMASTER model the logical watch of choice as aviation watches.
