Notes

The ?World Time? system was invented around 1935 by Louis Cottier (1894-1966), famous independent watchmaker in Geneva. This ?World Time? system was 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 Timers? from 1937 to the mid-1960?s: 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 known and only three examples are known today. One was sold by Antiquorum, in Geneva, on April 10, 1994, lot 502, for SFr. 550'000 (US$ 388,560). Ref. 542 HU (Ø 28 mm.), started around 1937, bears the names of approximately 30 cities in the world on the revolving bezel. Only 4 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). - Geneva, April 10, 1994, lot 500, at SFr. 231'000 (US$164,200) with unusual bezel and hands. - Geneva, October 15-16, 1994, lot 608, at SFr. 110'000 (US$ 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, in Geneva, on April 18-19, 1998, lot 40, for SFr. 355?500 (US$ 235,000), establishing a world record for this type of watch.
