The Retrograde Perpetual Calendar Rare Handcrafts Reference 5160/500 is reinterpreted in a new rose gold version with a silvery opaline dial.

The dial center, bezel, case middle, crown, hinged cover and lugs, as well as the fold-over clasp and strap screws are adorned with richly hand-engraved decoration composed of volutes and foliage inspired by a pocket watch from the Patek Philippe Museum.

Self-winding 26-330 S QR caliber drives displays of day, leap-year cycle and month through apertures at 9, 12 and 3 o'clock. The date is indicated by a retrograde hand sweeping over an arc between 8 and 4 o'clock.

The Officer’s-style case features a sapphire crystal case-back protected by a hinged cover.
