The brilliance of baguette-cut diamonds

Heir to a classic launched in 1941, this perpetual calendar chronograph is one of Patek Philippe's most prized complication combinations. The aesthetic harmony of this platinum version set with baguette-cut diamonds is complemented by a lacquered black dial. The manually wound movement combines traditional construction with six patented innovations.
