Description
The self-winding caliber 26-330 S C J SE movement drives the revolutionary weekly calendar complication within this 40mm stainless steel case, marking Patek Philippe’s first foray into steel for the Calatrava Weekly Calendar collection. Reference 5212A-001 showcases its silvery opaline dial through a sapphire crystal case back, revealing the intricate mechanics that power the unique seven-day calendar display alongside traditional month and date functions. This unworn example represents Patek Philippe’s mastery of contemporary complications, housed in the understated elegance that defines the Calatrava lineage while introducing the accessibility of steel construction to this sophisticated calendar system.
