ABSTRACT:
A world time multi-function watch for providing the local time at any location on earth by entry of the cartesian coordinates of that location through the bezel of the watch or by means of a GPS unit. The bezel is a high resolution input device which enables the cartesian coordinates to be input in increments of one degree. The coordinates are used to access a database of world time zones to determine the time zone in which the entered coordinates lie. Appropriate adjustments are made to reflect time zone adjustments with respect to a predetermined reference time line and to reflect the local observance of daylight savings time. One set of analog hands will automatically move to display the time at the selected location. The watch can be linked to a GPS unit through an optical, spread-spectrum rf or cable interface, by manually entering the information through the bezel, or through a wrist mounted unit linked directly or through an appropriate interface.
