The Patek Philippe Perpetual Calendar 5160R-001 is a variation of the 5159 with an intricately hand-engraved case and clasp. The center of its dial features a pattern matching that of the case. It was introduced at BaselWorld 2013. As is the 5159, the 5160 is powered by the caliber 324 S QR movement with perpetual calendar and retrograde date hand.
