The culmination of Patek Philippe's Annual Calendar in its most technically elevated — and visually striking form. The 5450 pairs the complete Oscillomax system GyromaxSi balance wheel, Spiromax hairspring and Pulsomax silicon escape wheel — with one of the most coveted dial colours in the Patek palette. The salmon dial lends this already exceptional piece a warmth and distinction that sets it apart from every other reference in the Advanced Research series. Limited to 300 pieces. A technical masterpiece with the soul of a dress watch.
