Object description

Case and Dial Design

The timepiece is housed in a 39mm 18K rose gold case, utilizing a tonneau shape. The design incorporates a smooth bezel with polished finishing and utilizes a sapphire crystal to cover the dial. The side of the case features a crown signed with the Patek Philippe emblem.

The silver dial is designed with three distinct apertures for the calendar functions, displaying the day, date, and month. It is finished with applied dart indices and prominent Breguet-style numerals at the 3 and 9 o'clock positions. The handset consists of dauphine-style pointers. A sub-register at the bottom of the dial indicates a 24-hour cycle and incorporates a moonphase aperture.

  • “day-date-month indicators north of center, a 24-hour subsidiary register with moonphase display”

Movement and Technical Configuration

Internally, the watch is driven by the Patek Philippe Calibre 324, a self-winding mechanical movement. This caliber provides the annual calendar complication, which manages the date display automatically across different month lengths, requiring manual adjustment only once per year.

The movement is viewable through the rear of the watch, which is fitted with a sapphire exhibition caseback. This aperture allows for direct observation of the mechanical components of the Calibre 324 while the watch is in use.

Provenance is supported by the original Certificate of Origin provided with the set. This document is dated February 2009. The watch is currently fitted with a brown alligator leather strap, which is equipped with an 18K rose gold pin buckle.
