No longer in production, this Patek Philippe ref. 5146J Annual Calendar remains one of their most important innovations. Requiring just one correction a year (end of February to March), it quickly became a flagship complication, and one that's now utilised across Patek's catalogue. 

Within its 39mm solid yellow gold case, the slate grey dial elegantly displays the day, date, month, moonphase display and power reserve - a harmony of multiple complications. Equipped with Calibre 324 S IRM QA LU and a 45 hour power reserve, waterproof to 30m.

This outstanding example is fitted to a brand new brown Patek alligator strap, fastened by a solid gold Calatrava deployant clasp. Complete with its original Patek box, Patek certificate d'origin dated September 2007, instruction booklet and setting stylus. Covered by our two-year warranty.
