Only the masters at Patek Philippe can make a complicated watch look and feel uncomplicated. 

The introduction of the ref. 5050 was an important milestone in Patek’s distinguished history of producing perpetual calendar wrist watches. Modelled after a unique retrograde perpetual calendar housed in a yellow-gold ref. 96 Calatrava case by Patek Philippe in 1936, the 5050 was the first serially produced watch to combine the classic perpetual calendar with the quirky retrograde complication.

The ref. 5050J features a 35 mm yellow-gold Calatrava style case. The silver opaline dial features simple applied 18k yellow-gold baton indexes and an elegant 18k yellow-gold feuille (leaf) handset.

The complications are displayed in an atypical manner. While perpetual calendars traditionally display the calendar in three sub dials, the reference 5050 features a retrograde date display that is arced over the top half of the dial and is read with the help of a centrally mounted hand. As the retrograde mechanism switches between two months, the date hand instantaneously resets to the 1st of the new month.

The day and month, on the other hand, are displayed in two apertures placed at the 9 and 3 o’clock positions, while an aperture at the 12 position houses the leap year indicator. Only the moon phase indicator is found in its traditional position at 6 o’clock.

The perpetual calendar mechanism can create a lot of visual clutter, even more so when combined with a showy retrograde complication. Yet, the dial of the ref. 5050 is a study in legibility and harmony. In fact, it’s a textbook example of how to make a complicated watch look uncomplicated.

When the watch is turned around, a sapphire display case back provides an unobstructed view of the beautiful hand-finished automatic movement with a 21k yellow-gold rotor. 

The watch dates back to 1994 and comes on a brown alligator leather strap with an 18k yellow-gold Patek Philippe buckle. The original Patek Philippe box is included as well as the Extract from the Archives.
