Patek Philippe 5140J Perpetual Calendar 18K Yellow Gold Silver Dial

The Patek Philippe 5140J-001 Perpetual Calendar stands as a testament to the manufacture's enduring mastery in haute horlogerie, replacing the renowned reference 3940 upon its release in 2006. Crafted in 18k yellow gold, the 5140J embodies a refined evolution of Patek’s perpetual calendar lineage, with a perfectly sized 37.2mm case that caters to collectors who appreciate classic proportions. At its heart beats the ultra-thin, self-winding caliber 240 Q, distinguished by its micro-rotor architecture and impressive 48-hour power reserve. This movement elegantly orchestrates a full perpetual calendar, displaying the day, date, month, leap year, moon phase, and 24-hour indicator in impeccably balanced subdials. The silver dial, adorned with applied gold markers, exudes quiet sophistication, while the sapphire display back allows an unobstructed view of the hand-finished movement. Water-resistant to 30 meters and accompanied by a matching solid gold deployant clasp, the 5140J blends daily practicality with undeniable prestige. This reference is a bridge between Patek’s revered past and its innovative present, revered for both its technical prowess and its desirability among connoisseurs. Saw limited production until it was replaced by the 5327 series, ensuring its continued relevance as a collector’s piece. Complete examples with box, solid caseback, setting pin, and papers—like this offering—underscore the 5140J's enduring allure and investment potential within the perpetual calendar pantheon.
