Patek Philippe Complications 5212A-001 Calatrava Weekly Calendar

The Patek Philippe Reference 5212A-001 Calatrava Weekly Calendar features a 40 mm stainless steel Calatrava-style case, a rare material choice in the brand’s complication line, and is water-resistant to 30 m. Its silvery opaline dial introduces a unique weekly calendar function, displaying the current week number alongside the day, month, and date. This layout is brought to life with distinctive handwritten-style typography, evoking the charm of personal annotations. Complemented by faceted anthracite white gold dauphine hands and applied “obus”-style hour markers, the dial achieves a balance between traditional elegance and contemporary design.

Inside, the automatic Caliber 26-330 S C J SE powers the timepiece, developed specifically for this calendar configuration. It drives the central sweep seconds hand along with dedicated displays for the day, date, month, and week number, each operated via individual hands and windows for clarity. The two-tier case structure with gently curved lugs and a sapphire crystal case back highlight the refined craftsmanship of the movement within. Paired with a brown hand-stitched calfskin strap and a stainless steel tang buckle, this Calatrava offers a blend of practical utility and timeless sophistication.
