Reference 5050
Reference 5050, Patek Philippe's first perpetual calendar wristwatch featuring a retrograde date made in series, was introduced at the Basel Fair in 1993, cased in yellow gold only. As of 1995, it was also available in pink gold, white gold and platinum but still exclusively with the silvered dial, applied Roman numerals, aperture for the moon phases, the very first examples with outer railway minute divisions. Following substantial demand from clients, Patek Philippe introduced a second version featuring applied baton indexes, a modified moon phases display now in form of a circular subsidiary dial, outer beady minute divisions and the addition of the designation "Automatic".
Discontinued in 2002, reference 5050 is today a highly sought after collector's watch, a modern classic enjoying popularity both amongst scholars and aficionados for day to day wear.

Reference 5050 is illustrated in Patek Philippe Wristwatches by Martin Huber & Alan Banbery, second edition, p. 296.
