The new perpetual calendar with a retrograde date hand in an Officer’s-style case is a Patek Philippe tribute to artisans who master rare handcrafts. The center of the dial, the white-gold case, the hinged cover, and the clasp are lavishly decorated with manually executed engravings inspired by a pocket watch that belongs to the Patek Philippe Museum’s collection.
