Casio GPW-1000 combines Multiband 6 capability to receive any one of six time calibration signals around the globe with a receiver that acquires position and time information from GPS satellites. When GPS information is acquired the watch determines your current time zone and judges whether or not your location requires the use of summer time, and updates watch settings accordingly. The combination of these two capabilities creates a hybrid timepiece designed and engineered to ensure that you are on time all the time, no matter where you happen to be. A dial at 8 o’clock shows World Time, so the current time in two time zones can be viewed at a glance. An Airplane Mode simplifies the task of disabling and re-enabling signal emission by the watch as conditions require.
