If you have family or business contacts across different countries and time zones, this impressive device is sure to help you stay connected. Called the Geochron World Clock, it is a full-color moving map used by NASA to aid satellite tracking and the Pentagon to synchronize troop deployment – elegantly displaying the time throughout the world at a glance.
Revolving in its frame at precisely the same speed as the Earth’s rotation, the Geochron World Clock features a 15 x 26-inch map that continuously displays the areas of our planet that lie in daylight or darkness at any given time.
With an analog dial system that cleverly charts the world’s 40 time zones on a 24 hour scale, the Geochron World Clock is backlit by two 15-watt fluorescent tubes and features light-diffusing, cam-driven mylar panels (for the dark areas) that adjust automatically for changes in seasons and daylight saving time.
Including a moving calendar displaying the date on both sides of the international date line plus the month and day of the week, the Geochron World Clock also shows moments of sunrises and sunsets and the length of daylight/darkness in global locations.
With an easy-clean black laminate and glass exterior plus updatable time zone maps, the Geochron World Clock measures 34 1/4″ wide x 22 3/8″ high x 5″ deep, weighs 28lbs, includes mounting brackets, plugs into AC and is available now from Hammacher Schlemmer for $1800.
