PATEK PHILIPPE, REF. 5160/500G-001, A VERY RARE AND FINELY HAND ENGRAVED 18K WHITE GOLD PERPETUAL CALENDAR WRISTWATCH WITH RETROGRADE DATE DISPLAY, LEAP YEAR INDICATOR, AND OFFICER’S CASEBACK

Reference 5160 is based on reference 5159 with perpetual calendar, retrograde date and sweep center seconds, but the case, dial and clasp are enhanced by highly ornamental and delicate hand engraving. Reference 5160 has long been characterized as a highly complicated wristwatch exuding exclusivity, rarity and artistry.

The piece is a remarkable combination of heritage techniques and modern horology. The movement is among the best center seconds perpetual calendar automatic movements currently in production. Aesthetically, the officer-style case with screw strap bars and hinged cuvette is a nod to historical watches of the early 20th century, as well as the overall dial design with radial Roman numerals and the fifth of a second and Arabic 5 minutes outer divisions. The engraved case with its floral motif typical of the Belle Epoque is reminiscent of the artful decorations of vintage pocket watches.
