Patek Philippe 5140R-001 (Pre-owned - Excellent) — USD 46,599 on eBay

The Patek Philippe Grand Complications reference 5140R-001 is a perpetual calendar wristwatch, introduced in 2006 as a successor to the long-running reference 3940. This model represents a modernization of Patek Philippe's classic perpetual calendar design, offering updated proportions while retaining the core aesthetic and functionality that collectors associate with the brand's complicated timepieces. It is part of the Grand Complications collection, signifying its advanced mechanical complexity. This specific reference features a rose gold case, housing an ultra-thin self-winding mechanical movement, the Caliber 240 Q. The movement is known for its compact design, allowing for a relatively slender case profile. The perpetual calendar mechanism accurately displays the day, date, month, leap year cycle, and moon phases, requiring no manual correction until the year 2100. A sapphire crystal protects the dial, and a sapphire crystal case back allows for viewing of the movement. The 5140R-001 appeals to collectors seeking a contemporary interpretation of a traditional Patek Philippe perpetual calendar. It builds upon the legacy of the 3940, offering a slightly larger case diameter that aligns with modern preferences while maintaining a classic and understated presence. The rose gold case with its specific dial configuration distinguishes this particular variant within the 5140 series.
