Introduced in 2005, the Patek Philippe ref. 5146 features an annual calendar complication and is the second annual calendar model ever produced by the brand. It succeeded the ref. 5035, the first annual calendar reference introduced in 1996, and retains a similar aesthetic. Before the annual calendar wristwatch was released, collectors had to choose between highly complicated perpetual calendar watches and simple triple calendars, leaving a gap that the annual calendar effectively filled.

Housed in a sophisticated 39mm 18K yellow gold Calatrava-style case, the ref. 5146 exudes a traditional and timeless charm. What makes this timepiece particularly special is its dial. This example, fresh-to-the-market, comes from its original owner who purchased it in 2006 at the Patek Philippe Salon in Geneva and still retains the original purchase invoice. The grey dial is exceptionally rare compared to its ivory counterpart, with only a few examples having surfaced. This piece marks Phillips' auction debut for this reference, making it stand out among its peers. The striking combination of the grey dial against the yellow gold case offers a unique opportunity for connoisseurs who appreciate such elegant timepieces.
