Original Listing Description

eBay Physically, the Geochron looks like a framed world map, about 2? x 3? ft. in size. The colorful map is an endless belt that is driven slowly from left to right by an electric clock motor in synchronism with the rotation of the earth. It’s a clock, it’s a conversation piece, it’s a hand-made work of art. All known legal time zone boundaries are delineated on the map by dark blue lines which in most cases, converge on lettered pointers on the top edge of the map. These letters identify the standard time zones and also represent the short wave radio prefix for that zone. The Geochron is the only mechanical chronometer to simultaneously display the current time and the sun’s Event Horizon simultaneously, anywhere in the world. As an added extra of this one-of-a-kind project, they are custom made to every order! The Geochron Illustrates: Legal time zones Greenwich Mean time Greenwich Apparent time Local Apparent time (in 12 or 24 hour) Moment of sunrise Moment of sunset Duration of daylight Sun’s meridian passage Sun’s equation of time Degrees of latitude and longitude Geochron History The Geochron was invented by James Kilburg with the idea that one device could be used to determine what time it is anywhere in the world. Kilburg was a mechanical engineer who perfected his craft and knack for ingenuity while living in Luxembourg. After moving to America, Kilburg devoted his life to creating innovations such as the car cigarette lighter, the first automatic dialing telephone, as well as the automated maraschino cherry pitter. After more than 50 years, the Geochron is still assembled by hand in Portland, Oregon. It takes four clockmakers three days to build a clock, then a “burn-in” on the test wall. Each Geochron passes through multiple quality inspection checks along the assembly process, including a rigorous 28 point inspection over two days prior to shipping. The Geochron has been used by world renowned business leaders, dignitaries and diplomats and even by those in the White House. President Reagan gave one to Mikhail Gorbachev as a gift.WEIGHT 35 lbsDIMENSIONS 24 × 7 × 36 inTIME BAND 12 Hour, 24 HourPUBLISHER English (Condition: New (Other))
