Patek Philippe’s first chronograph movement
As surprising as it may seem, the large manufacture, Patek Philippe,didn’t have a chronograph movement that was totally designed, developed, and produced in-house. Now it does. Introducing the new calibre CH R 27-525 PS.
Under this rather dry-sounding name, can be found the world’s flattest column-wheel chronograph movement, with a thickness of 5.25 mm. This is a grand premiere because up to now, as a base for its chronographs, Patek Philippe had used a Nouvelle Lémania calibre produced exclusively for the Geneva brand. Based on the CH 27-70, the movement gradually added a perpetual calendar and a continuous flyback function
