GWIS's recent acquisition of the Patek Philippe Ref. 5236P-001 Perpetual Calendar marks a significant moment for any collector. His detailed review offers a rare, firsthand perspective on what makes this platinum timepiece a 'grail-level' watch, balancing horological complexity with understated elegance. This article distills community insights, providing a comprehensive look at the 5236P's appeal and nuances for both seasoned enthusiasts and those new to Patek Philippe's perpetual calendars.





The Complications reference 5236P-001, introduced in 2021, is notable for its in-line perpetual calendar display. This configuration presents all calendar indications – day, date, month, and leap year – in a single, elongated aperture below 12 o'clock. This design choice offers a distinct aesthetic and legibility compared to traditional perpetual calendars with multiple subdials or apertures. The reference was a significant addition to Patek Philippe's Complications collection, showcasing a novel approach to a classic grand complication. Its platinum case and blue dial further underscore its position within the brand's high-end offerings.
The watch is housed in a platinum case measuring 41.3mm in diameter, with a thickness of 11.07mm. It is powered by the self-winding caliber 31-260 PS QL, a movement specifically developed for this in-line perpetual calendar display. This movement incorporates several technical advancements to achieve its unique calendar presentation and offers a power reserve of 38 to 48 hours. The watch features a sapphire crystal on both the front and the case back, allowing for a view of the meticulously finished movement.
As a relatively recent introduction that was subsequently discontinued, the 5236P-001 holds particular interest for collectors who appreciate innovative calendar displays and limited production periods. Its technical sophistication and unique aesthetic appeal to those seeking a distinct perpetual calendar from Patek Philippe. The discontinuation of a model introduced in 2021, while not uncommon for certain high-end references, adds to its potential collectibility, distinguishing it from longer-running production pieces.
The blue brushed dial is sublime. The brushing is done by hand using a traditional method in PP’s dial manufacturing workshop. Quite something to see.
You didn't mention the very beautiful architecture of the movement which, to me, is an important part of its appeal. The only thing missing in such a caliber is one or two sharp interior angles. Enjoy your grail in good health and with your daughter!
Now this is something special. Great description and fantastic photos to top it all… Enjoy the honeymoon! Best, Zsolt.
to this grail! I enjoy it very much too and really prefer the blue dial. The salmon is kind of „dead“ in comparison. The nubuck strap from the 5172 is a good alternative to the original strap as it matches the dial very well:
Many thanks for the information about the dial.
You are quite right, the architecture of the movement is great. I wasn’t happy with the pictures I took of the movement and so I didn’t include them in the end.
