Patek Philippe 5100P and 5500G Collection

Rolex Air-King Reference 5500

The Reference 5500 represents the black dial steel variant within the Air-King model range. Produced from 1972 to 1989, this reference spans nearly two decades of Rolex's catalog, offering the Air-King configuration in stainless steel construction with contrasting black dial presentation.

The 34mm stainless steel case houses the automatic Caliber 1520 movement, providing 42-48 hours of power reserve. The watch features a fixed bezel, acrylic crystal, and 100-meter water resistance. The black dial is paired with a steel bracelet, creating a monochromatic steel and black aesthetic throughout the watch.

This reference appeals to collectors seeking vintage Rolex pieces from the 1970s and 1980s production era. The 34mm case size and automatic movement position it as an accessible entry point within vintage Rolex collecting, while the extended production period means examples can be found across various condition grades and price points.

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.
