The 27 AM 400 is a manual-winding caliber introduced by Patek Philippe in 1950. It belongs to the caliber 27 family and was produced as an antimagnetic movement designed for the Calatrava collection. As an in-house movement, it reflects Patek Philippe's proprietary approach to watchmaking during the mid-20th century. The caliber was discontinued, making it a vintage reference among collectors.
