A jewellery version of a Patek Philippe classic, Reference 5271/12P-010 is lit up by 80 baguette-cut rubies (5.25 cts) set on the bezel, the lugs and the fold-over clasp. The intense colour of the gems is echoed by the lacquered red dial with black-gradient rim and the shiny black alligator strap with contrasting stitching. The CH 29-535 PS Q caliber is distinguished by its traditional architecture (manually wound, column wheel, toothed-wheel horizontal clutch), combined with six patented innovations in the chronograph, as well as its exceptionally slim calendar mechanism.

Patek Philippe has created a new alliance between Haute Horlogerie and Haute Joaillerie by reinterpreting its most complicated wristwatch in a white gold version set with 118 baguette-cut emeralds (7.87 cts) and 291 baguette-cut diamonds (20.54 cts), using the “invisible setting” technique. Among the 20 complications are five acoustic functions, including two patented world exclusives: an alarm sounding the programmed time and a date-repeater striking the date at will. The reversible double-sided case is distinguished by its patented swivel mechanism, enabling it to be worn with either dial visible. This watch is accompanied by white gold cufflinks set with a row of baguette-cut emeralds.
