Emmanuel, known as quattro on WatchProSite, introduces a rare Patek Philippe Weekly Calendar Calatrava reference 5212A-010. This article delves into Emmanuel's detailed presentation of the limited-edition burgundy dial variant, created to celebrate 50 years of partnership with Austrian retailer Juwelier Heldwein. His post provides an invaluable first look at this exclusive timepiece, offering context and high-quality images for collectors.

This burgundy dial variant of the regular Patek Philippe Weekly Calendar Calatrava was made in 2024 to celebrate 50 years of partnership with Austria-based Juwelier Heldwein.

The ref. number is 5212A-010 as opposed to the 5212A-001 of the regular version.

The sapphire case back says β€œPatek Philippe & Juwelier Heldwein – 1974-2024 – 50 years of collaboration”, but I have been unable to find some photos of it.

Only 20 pieces were made.

Do you like it?

Best, Emmanuel

About the Patek Philippe Weekly Calendar Ref. 5212A-001

The Calatrava reference 5212A-001 introduced the Weekly Calendar complication to the Patek Philippe lineup. This model features a unique hand-written style typography for its calendar indications, distinguishing it from other calendar watches in the brand's collection. It represents an accessible entry point into Patek Philippe's complicated timepieces, offering a practical function in a non-precious metal case.

The watch is housed in a 40mm steel case, a notable choice for a Patek Philippe complication, and is fitted with a sapphire crystal. It is powered by the self-winding caliber 26-330 S C J SE, which provides a power reserve of approximately 35-45 hours. The movement is visible through a sapphire crystal case back, allowing appreciation of its finishing.

This reference appeals to collectors seeking a distinctive and functional complication from Patek Philippe outside of the traditional annual or perpetual calendars. Its steel case and unique dial layout offer a different aesthetic compared to the more formal Calatrava models, making it a versatile option within the brand's contemporary offerings. The 5212A-001 is a regular production model, contrasted by limited editions such as the 5212A-010.

But the laziness of not changing the date wheel a tad less so. But then again it’s not color matched to the dial on the original, either πŸ€·πŸ»β€β™‚οΈ

It's surprising that Heldwein didn't ask for such a refinement for such an anniversary piece (a 50th anniversary only comes every 50 years, doesn't it πŸ˜…)! Best, Emmanuel

And 60k for such a watch is simply ridiculous. Best, Emmanuel
