Pre-Owned Patek Philippe Complications Ref. 5212A

Patek Philippe Ref. 5212A is the Calatrava Weekly Calendar, a self-winding Complications watch introduced at Baselworld in 2019 and discontinued after 2025. The standard Ref. 5212A-001 pairs a 40 mm stainless-steel case with a silvery opaline dial, light-brown calfskin strap, and handwritten-style calendar typography. Five centrally mounted hands indicate the time, day, and week number with month, while the date appears through an aperture at 3 o'clock. Its calendar follows ISO 8601, beginning each week on Monday and defining the first week as the one containing January 4; it also accounts for years with 53 weeks. The 5212A matters as Patek Philippe's first serially produced wristwatch with a weekly-calendar complication and as the debut platform for the self-winding calibre 26-330 S C J SE. Its semi-integrated calendar mechanism adds 92 parts to the 212-part base movement, bringing the complete calibre to 304 parts within a thickness of 4.82 mm. The stepped bezel and curved double-godron lugs draw from the unique 1955 Ref. 2512, whose reference numerals were reversed for the modern 5212. Two separate anniversary executions followed the standard model: the burgundy-dial 5212A-010 for Juwelier Heldwein in 2024 and the ice-blue 5212A-012 for KUTTER 1825 in 2025, each limited to 20 pieces. Every watch available through The 1916 Company is authenticated and backed by The 1916 Company's 2-year warranty.
