Self-winding
28-28
This skeleton, square shaped, self-winding movement is a masterpiece of harmony and integration between design and watchmaking. The mainplate and bridges have been openworked endowing it with both transparency and elegance. Another original feature — and a first for Patek Philippe — is the fact that the movement is presented in a monochrome aesthetic.
