Patek PhilippeAnnual Calendar

Offered by a UK-based trade seller, this Patek Philippe ref. 5146J is presented with its display box and an Extract from the Archive from Patek Philippe outlining its provenance. The watch shows some marks and swirls on the case and some light wear to the leather strap, and its condition appears to be within the bounds of the vendor’s ‘A’ grading. 

The case of this second-generation Annual Calendar measures 39mm in diameter - increasing in size from the original reference 5035 that debuted in 1996. Constructed from 18K gold with a crisp white dial and applied gold hour markers, the watch is both elegant and eye-catching. From all angles, the watch is nicely balanced with the complications laid out symmetrically.

An exhibition case back displays the expertly finished calibre 324 S IRM QA LU movement, which is elaborately decorated with Côtes de Genève across the bridges and 21K winding rotor. The watch is paired with a factory alligator strap and signed Patek yellow gold deployant clasp. 

Originally debuted in 2005, the reference 5146J represents the second generation of annual calendar watches for Patek Philippe. An important piece in the company’s catalogue, the patented movement was invented by Patek Philippe and only requires the wearer to adjust the date once a year.
