Patek Philippe 5935A-001 (New with box and papers) — USD 56,999 on eBay

The Patek Philippe Reference 5935A-001 is a notable entry in the brand's World Time Chronograph series, distinguished by its stainless steel case. This reference represents a contemporary interpretation of Patek Philippe's long-standing tradition of combining complex functionalities, specifically a flyback chronograph with a world time display, in a material rarely seen in such complicated pieces from the manufacturer. Its introduction in steel makes it a distinctive offering within a lineage typically associated with precious metals. This choice of material underscores a modern approach while retaining the intricate horological craftsmanship expected from Patek Philippe. This timepiece features a self-winding mechanical movement, the Caliber CH 28-520 HU, which integrates both the flyback chronograph and the world time mechanisms. The case, crafted from stainless steel, measures 41mm in diameter and is fitted with a sapphire crystal case back, allowing for observation of the finely finished movement. The front crystal is also sapphire. The movement provides a power reserve of approximately 50-55 hours, ensuring reliable performance for daily wear. For collectors, the 5935A-001 holds particular appeal due to its stainless steel construction, which is uncommon for Patek Philippe's highly complicated watches. This characteristic positions it as a unique and potentially sought-after reference, appealing to those who appreciate the brand's technical prowess combined with a more understated and contemporary material choice. It stands as a testament to Patek Philippe's ability to innovate within its established catalog, offering a fresh perspective on a classic complication.
