Lot Essay
Reference 605 stands as Patek Philippe’s pocket-watch interpretation of the World Time (Heures Universelles) mechanism conceived by Louis Cottier. Cottier first presented Patek Philippe with his 17-ligne world-time calibre in 1937. Between 1938 and 1939, he delivered the first two examples, one of which is considered a prototype. Only 88 world-time movements were finished by Cottier up until 1964, with three movements being supplied in 1940 and five in 1941.
With a total production of well under 100 pieces, reference 605 HU is an extremely rare model that houses the great majority of these movements. Consigned by an important private collector, distinguished for a discerning focus on complicated pocket watches and a deep appreciation for horological excellence, the present example has the traditional and exquisitely silvered dial, which has long been regarded as the most archetypal representation of the model. A few other dials were made in enamel, champagne, or pink colors, and even a very rare black version made upon special request.
Notably, when this timepiece first appeared at public auction more than 30 years ago, it was already engraved with the Geneva coat of arms, a historically significant detail underscoring its early recognition and importance.
Heure Universelle & Louis Cottier
Louis Cottier (1894–1966) created the world-time, or Heure Universelle, mechanism in 1931, and it soon rose to prominence as one of the most significant complications of the 20th century. Several of Switzerland's top watchmakers, including Patek Philippe (references 605, 1415, and 2523), Vacheron Constantin (ref. 3372), Agassiz, and Rolex (ref. 4262), adopted his innovative system.
Cottier improved his creation in 1953 by adding a mechanism that used a secondary crown to adjust the city disc. The Heure Universelle became one of the most elegant and useful complications ever created when Patek Philippe was able to patent a system in 1958 that allowed the hour hand to be independently adjusted without halting the minute hand's continuous progression.
