Case and Dial Construction

The Reference 5040P is characterized by its tonneau-shaped case constructed from platinum. This design deviates from traditional round profiles and retains the manufacturer's crown, which bears the Patek Philippe cross. The case back is reported to show gentle wear, while the sapphire crystal remains free of scratches. The brushed silver dial features applied Breguet numerals. The layout includes a perpetual calendar with a 24-hour indicator situated at the left sub-dial. The moonphase disc is described as being in flawless condition. The 24-hour indicator displays a two-tone aesthetic, where the bottom half of the circle shows a golden brown finish.

Movement and Functionality

This watch utilizes the Caliber 240 Q movement. This is an automatic, ultra-thin caliber equipped with a micro-rotor, a feature noted by the manufacturer for its ability to maintain a slim profile for the watch case. The movement facilitates the perpetual calendar complications, which include the tracking of the day, month, date, leap year, and moonphase. The vendor reports that the watch is currently keeping time and functioning correctly. No specific records of previous maintenance or service are available for this unit.

Documentation and Provenance

The timepiece is supplied with its original black alligator leather strap and a platinum deployant clasp. As part of the acquisition process through the vendor, an Extract from the Archives has been requested from Patek Philippe to document the watch's origins. The serial number is listed as 47XXXXX / 36XXXXX, and the model is defined under the reference 5040P.
