Notes

The "World Time" system This system was invented around 1935 by Louis Cottier 1894-1966, a famous independent watchmaker in Geneva and is used by Patek Philippe and by other major names in the Swiss watch industry, such as Agassiz, Rolex and Vacheron Constantin. Patek Philippe created various series of "World Times" from 1937 to the mid-1960s: Ref. 515, a rectangular "galbé" pink gold model made in 1937, with the names of 28 cities in the world on the dial, the time differences between them based on Greenwich Mean Time. It is the earliest of the "World Time" pieces and only three exam-ples are known today, one of which was sold by Antiquorum Geneva on April 10, 1994, lot 502, for SFr. 550,000 US$ 388,560. Ref. 542 HU Ø 28 mm., was started around 1937, and bore the names of approximately 30 cities in the world on the revolving bezel. Only four examples are known to date, three of which were sold by Antiquorum Geneva: October 17, 1993, lot 431, at SFr. 121,000 US$ 81,700; April 10, 1994, lot 500, at SFr. 231,000 US$164,200 with unusual bezel and hands; October 15-16, 1994, lot 608, at SFr. 110,000 US$ 87,300. Ref. 96 HU Calatrava, with the names of 28 cities in the world on the dial, appears to be an unique example made in 1939. Ref. 130, of which only one example is known and was made on special order by Patek Philippe in 1939, is an 18K yellow gold mnemonic "World Time" chronograph wristwatch, with square push buttons, register and tachometer. This watch does not have a "World Time" movement but features a "World Time" dial with the names of 24 cities of the world. The time difference between the various cities is based on Berlin, which is placed at noon. This watch was sold by Antiquorum Geneva on April 18-19, 1998, lot 40, for SFr. 355,500 US$ 235,000, establishing a world record for this type of watch. Ref. 1415 HU was produced around 1939-40. It has drop-shaped lugs, a diameter of 31 mm. and, on the revolving bezel, the names of approximately 30 to 41 cities in the world. This model was produced in: yellow gold with silvered dial; in yellow gold with cloisonné enamel dial representing various continents; pink gold, with silver, champagne or pink dial; platinum with silvered dial; and pink gold, with a cloisonné enamel dial representing various continents. Antiquorum Geneva sold one on November 13-14, 1999, lot 520, which set a World Record at SFr. 1,345,500 US$ 868,065 for this model. Ref. 1416 HU is similar to Ref. 1415HU and was produced at the same time, with the only difference in its straight "claw" lugs. Three examples are known today. Ref. 1415-1 was created in 1940, especially for Dr. P. Schmidt. This is a unique "World Time" chronograph wristwatch, in yellow gold, with square push buttons and the names of 33 cities of the world. It was auctioned by Antiquorum Geneva, on October 15-16, 1994, lot 516, setting, at the time, a World Record, at SFr. 990,000 US$ 785,714. This watch is illustrated on the front cover and p. 270 of the 1998 edition of "Patek Philippe Wristwatches", by Martin Huber & Alan Banbery. Ref. 605 HU was produced circa 1940-1960?s and is a series of dress watches, with the names of approximately 30 to 41 cities in the world on the revolving bezel. Some examples have a matte silvered dial or black dial and others have a cloisonné enamel dial. Ref. 2523 HU and Ref. 2523-1, with two crowns, were produced circa 1953-1965: they bear the names of approximately 40 cities of the world on the revolving bezel. They were made in: pink gold, with silvered guilloché dial; pink gold, with translucent enamel dial; pink gold, with cloisonné enamel dial representing various continents; yellow gold, with silvered guil-loché dial; yellow gold, with translucent enamel dial; yellow gold, with cloisonné enamel dial representing various continents; and only one example known to date in white gold with cloisonné enamel dial represent-ing various continents.
