Patek Philippe 5212A-001 (Pre-owned - Good) — USD 37,704 on eBay

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.
