Patek Philippe Calatrava ref. 3569 backwinder

Patek Philippe Calatrava reference 3569 in 18k white gold, measuring 35.5mm and powered by the ultra thin automatic caliber PP 350 with peripheral winding rotor. Produced in 1970, the reference 3569 is among the most elegant and technically refined Calatrava references ever made, combining the purity of the Calatrava design with Patek Philippe’s mastery of ultra thin automatic movement construction. The peripheral winding rotor, an exceptionally rare feature at the time, allows the movement to be appreciated in its entirety without the obstruction of a conventional central rotor. The blue sigma dial is in outstanding condition, presenting with the deep, rich tone and crisp printing that defines the finest vintage Patek Philippe dial work, and in white gold creates a combination of cool refinement that is particularly sought after among serious collectors. Fitted on a non Patek strap and buckle. Brand: Patek Philippe Model: Calatrava Reference: 3569 Year: 1970 Movement: Automatic, Cal.
