These models feature a thick stepped round bezel, hence the nickname "Disco Volante," or flying saucer. The 2552 is among those Patek Philippe references blessed by the caliber12-600AT, the first automatic movement by Patek Philippe, universally considered one of the most outstanding automatic movement ever developed and an absolute example of industrial art. The most famously housed in reference 2526, this movement is the result of a momentous technical effort.

The architecture and size of this movement allow for particular positioning of the gears and for a relatively large balance wheel, for increased accuracy. The massive 18K rotor is ideal for capturing energy and its lavish finish betrays the care and attention Patek Philippe reserved to this caliber.
