Stainless steel Patek Philippe Calatrava wristwatch

Introduced in 1949-1950, the 12-400 is the known successor to Patek's famous 12-120 calibre. While maintaining the essential architecture, the 12-400 incorporated several critical improvements, including a redesigned regulator system enhancing the overall reliability. These refinements elevated the movement from a delicate dress-watch caliber into a far more versatile platform, capable of meeting the rigors of mid-century wristwatch use.
