The central part of the dial, the bezel, the middle part of the case, the crown, the hinged lid and the lugs, as well as the folding clasp and the screws of the strap are decorated with a hand-engraved pattern in the form of curls and leaves, which resembles the ornament on pocket watches from the Patek Philippe heritage collection.
