Reference 5050, Patek Philippe's first perpetual calendar wristwatch featuring a retrograde date, 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, an aperture for the phases of the moon, 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 moonphase display now in form of a circular subsidiary dial and the addition of the designation "Automatic".

Discontinued in 2002, the present lot is one of only 14 examples of reference 5050 in white gold to appear at auction to date.

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