This is a model from the G-Shock Gravitymaster Series for pilots who work in harsh conditions. It comes with an advanced World Time feature. It is an aviation watch for pilots who require different kinds of information and need to be able to display and check time information for a different time zone. The visibility of the home time has been improved through the use of broad hour and minute hands, while the local time is displayed in 12-hour format on the subdial, allowing you to check the current time in two cities at once. It also comes with a compass and temperature sensor and allows for continuous Compass and Temperature Measurement over 60-second periods. The high-luminance LED lighting also allows you to check the time and other information in the dark. The toughness and diverse range of functions have allowed the Gravitymaster to evolve in leaps and bounds as an aviation watch.
