Patek PhilippeThe Patek Philippe Reference 5146J is a self-winding annual calendar wristwatch featuring a moonphase complication. The watch is constructed with a 39mm 18K yellow gold case, which includes a polished bezel, a signed crown, and a sapphire crystal.
The white luminous dial displays applied hour markers, with subsidiary registers for the day and month, a date window at the 6 o'clock position, and a moonphase aperture. The hands are a luminous 'feuille' style. Internally, the watch is powered by the Calibre 315 S IRM QA LU self-winding movement. It is paired with a black alligator leather strap that attaches via a signed 18K yellow gold deployant buckle. The object is accompanied by a Certificate of Origin dated 2006, confirming its production era within the annual calendar line, a complication originally developed by Patek Philippe in partnership with the Geneva School of Engineering.

- Case and Dial Design
- The Patek Philippe Reference 5146J is housed in a 39mm 18K yellow gold case. The design incorporates a smooth, polished bezel and a sapphire crystal. The crown, situated on the side of the case, is signed. Integrated into the case band are push-button adjusters for the calendar functions. The dial is finished in white and features luminous applied indices and numerals. A 'feuille' handset, also luminous, indicates the time. Calendar information is presented through recessed subsidiary registers for the day and month, with a date window positioned at 6 o'clock. A moonphase aperture is also located in this lower section of the dial.
- Movement and Functionality
- This timepiece operates using Patek Philippe's Calibre 315 S IRM QA LU self-winding movement. This movement provides the annual calendar functionality, a complication that automatically accounts for the varying lengths of months, requiring manual adjustment only once per year at the end of February. The watch includes a moonphase display and a date window. The movement architecture relates to the broader development of annual calendar complications at Patek Philippe, which began following an initiative with the Geneva School of Engineering in 1991 to simplify the perpetual calendar mechanism.
