Patek Philippe · Automatic

324 S

A member of the 324 family Patek introduced in 2004 to replace the 315, and the movement behind two decades of Nautilus, Aquanaut and Calatrava references. Unlike the 240's recessed micro-rotor, the 324 winds from a full central rotor in 21-carat gold, which buys torque and winding efficiency at the cost of a little height. The balance is a free-sprung Gyromax.
