Ref. 5050
The first models of Patek Philippe's ref. 5050 in 1993 were produced as a yellow gold version only, to be followed by the full range in 1995: yellow gold, white gold, pink gold, and platinum. Opaline gray was the only dial-colour available for the four different metals, but a choice of either indexes or Roman numerals was offered. The ref. 5050 was the first Patek Philippe perpetual calendar wristwatch with a retrograde date. When the reference was first shown in 1993/1995, this complication went more or less unnoticed. However, when the watch was discontinued in 2001/2002 this became a sought-after complication, which was by then widely used by other brands. The well-known minute repeater ref. 5016 subsequently used this type of perpetual with retrograde date. With its small window displaying the day and month and the leap year indication, it was the successor to Ref. 3450, and like 3450, only produced in very small quantities.
