Launched at Baselworld in 2010, the Patek Philippe ref. 5160 was the answer of the evolution of the perpetual calendar with retrograde date ref. 5159. While both features a sophisticated officer style hinged caseback, the ref. 5160 is a showcase of Patek Philippe’s best known artisanal mastery with a hand engraved flourish. Presented as part of the rare handcraft collection, the master engraver proudly demonstrates their talent with the large Calatrava logo on the hinged caseback. Surrounded by gorgeous proportions and elegant foliate motif down to the edges of the straight lugs, the inspiration reminds one from the Patek Philippe Perpetual Calendar No. 979975 dated back to 1925. Only released in a small undisclosed number during the time, it is believed that no more than three dozens were made in each metal: yellow, white and pink gold. Featuring an engraved dial encircled with both Arabic and Roman numerals, the aesthetic of the timepiece is balanced and pleasing to admire.

What makes the present timepiece exceedingly exquisite is not only its early production of the reference from 2010, but it is the stunning white gold case that will definitely intrigue any collector. The fully engraved case in almost a gun metal shade gives this timepiece an extremely contemporary appeal. Such even and unique oxidation is not something you will see everyday, as we all known that these characteristics develop by random and only through time.

Well-preserved and accompanied by its original certificate and presentation box, this is arguably one of the most interesting complicated Patek Philippe models you will ever come across.
