The Patek Philippe Reference 605 HU (Heure Universelle) is one of the most historically significant world time pocket watches ever created. Produced between 1939 and 1964, it was developed in collaboration with master watchmaker Louis Cottier, who invented the world time mechanism that allows for the simultaneous display of 24 time zones.
