Patek Philippe 18K yellow gold ref. 5146J with cream dial, made and sold 2014 The ref. 5146 was launched in 2005 and replaced Patek Philippe’s first Annual Calendar, the ref. 5035. Made two mm larger, the 39 mm ref. 5146 had a number of design modifications as Patek Philippe evolved the Annual Calendar line. The roman numerals were left in the past and Arabic 9-12-3 was added with applied baton numerals. The date remained at 6 o’clock and a novel up-down indicator was added below 12 o’clock. This finely preserved and complete example is offered with its original Certificate of Origin, box and product literature.

The Patek Philippe Annual Calendar is a highly sophisticated watch combining technical ingenuity and ease of use, featuring complications that need to be adjusted only once a year. It displays the day, date, and month, adjusting automatically for months with 30 and 31 days. Launched in 1996, it was the first wristwatch to offer an annual calendar mechanism, symbolizing a significant milestone in watchmaking history.
