Girard-Perregaux Worldtimer “John Harrison”

Nice looking world timer from Girard-Perregaux, the new Worltimer honoring one of the greatest British watchmakers, John Harrison (inventor of the marine chronometer).  The dial of this exceptional timepiece depicts the journey undertaken by John Harrison’s son William from Portsmouth, England, to Port Royal, Jamaica, against a map of the Atlantic Ocean. The trip lasted from November 1761 to March 1762 and was intended to test the reliability of Harrison’s H-4 timepiece.  The H-4 was proven able to calculate a ship’s longitude to within half a degree, a breakthrough accomplishment for marine navigation.  A fitting tribute for one of history’s most important watchmakers!
