Patek Philippe In-Line Perpetual Calendar
Complete, Like New, 2023
Ref. 5236P-001

This Patek Philippe Ref. 5236P-001 Platinum Self-Winding In-Line Perpetual Calendar Is Complete. Accompanied with its certificate of origin, second case back, setting pin and automatic winding box. This example is like new with papers dated 2023.

The Patek Philippe Ref. 5236P-001 is a perpetual calendar with an original in-line display to its rich range of calendar watches. The day, date and month appear in a large single aperture at 12 o'clock. So as to combine originality, legibility and reliability, the watch design engineers have developed the new self-winding movement 31-260 PS QL with an additional in-line display module, for which three patent applications have been filed. This highly sophisticated new caliber is housed in an elegant platinum case framing a vertical satin-finished blue dial with a black-gradient rim. The dial is a masterpiece of elegance.

The Patek Philippe Ref. 5236P-001 case is inspired by vintage timepieces - ref. 3448 and 3450, specifically - and is based on the 40mm case of Regulator reference 5235, in this case upgraded to 41mm. The inspiration from this novel movement comes from a vintage timepiece, pocket reference 725/4 which features a similar indication (albeit in "American" style - month, date, day - rather than the present European style "day, date month"). The similarity between the two watches is however purely aesthetic, as the calendar module of ref. 5236 is completely new, a masterpiece of watchmaking featuring 118 additional parts compared the a "standard" perpetual calendar, and a number of technical solutions devised exclusively for this complication.
