Notes: Presented at Baselworld 2015, the Patek Philippe ref. 5905P features an elegant 42mm diameter platinum case with an annual calendar and a flyback chronograph complication. While most would agree that the resemblance in aesthetics is uncanny to the annual calendar ref. 5205, the ref. 5905 does not feature hollowed lugs such as the ref. 5205, but instead offering the wearer with an additional chronograph function with a larger case. Indicated through three apertures, the annual calendar shows the day, date and month above the signature providing the wearer with clear legibility. The reference was first available only in platinum with the release of an 18K pink gold variant introduced recently in 2019 by the firm with a “chocolate” brown dial. 

The present example Patek Philippe ref. 5905P features a blue dial from circa 2017.
A rarely collector opportunity for this only one Double factory seald on the market with the inscription “Anonymous” on the place of the name that of course make up the value.
