Nicolas (amanico) initiates a compelling discussion on the Patek Philippe Ref. 5100 'Ten Days,' a modern reference that continues to captivate collectors. His post delves into the allure of its distinctive case and the impressive 10-day manual winding movement, prompting a community-wide reflection on this significant Patek Philippe model. This article synthesizes collector preferences and insights, highlighting why the 5100 remains a coveted piece.

The Patek Philippe Calatrava reference 5100 was introduced in 2000 as a limited edition to commemorate the new millennium. This reference stands out within the Calatrava line for its distinctive 'Manta Ray' shaped case, departing from the more traditional round Calatrava forms. It was produced in very limited quantities across different precious metals, making it a notable special edition for collectors of the brand.
The 5100 features a manual-wind caliber 28-20/220, a movement specifically developed for this model, known for its elongated form to fit the unique case shape. The case is characterized by its rectangular, slightly curved profile with integrated lugs, and it is fitted with a sapphire crystal. The specific variant mentioned, the 5100P-001, is crafted in platinum.
This reference appeals to collectors who appreciate Patek Philippe's limited-production commemorative pieces and those drawn to watches with distinctive case designs. Its unique aesthetic and the bespoke movement developed for it position the 5100 as a significant, albeit unconventional, entry in the brand's modern history, particularly for enthusiasts of shaped timepieces.
It surprises me again and again how we share similar pov. The beauty and practicality of this series. The pain in winding it (not that far from speedy pain, but here it’s 10 days). The preferred P metal but the acceptable G for it’s pure beauty. All in all imagine a P 5135 in that blue dial…
My favorite is RG with the grey dial, so beautiful!
The blue dial 5124G is really nice and also criminally underrated, which is great
The white metal and blue dial are a winning combination. Dave
While fantastic from design and ergonomic view, the legibility was not so good due to the curved crystal. Winding it was a pleasure, even dough a bit too long…
A real "face in the crowd" watch !
