Girard-Perregaux has unveiled a limited series of watches as part of its ww.tc collection, dedicated to renowned British watchmaker John Harrison. He created a clock that would maintain its accuracy even when pitching and rolling on the world’s roughest seas. Born on March 24, 1693, he devoted his entire life to creating accurate timepieces. The Girard-Perregaux ww.tc Enamel to John Harrison watch’s dial depicts the journey undertaken by his son William from Portsmouth in England to Port Royal in Jamaica, against a map of the Atlantic Ocean, contours of which are engraved on an unprocessed plate of white gold. The compass rose shows eight directions of the wind and measures more than 3 mm hand-sculpted. The dial shows off delicate champlevé enamel, produced in the enameling workshop of the Girard-Perregaux Manufacture.
