Especially developed by Patek Philippe and Tiffany & Co. and released at the end of 2012 to commemorate the fifth anniversary of the Patek Philippe Boutique located inside the Tiffany & Co. flagship New York store, the Patek Philippe Annual Calendar ref. 5396G-012 is one of the most exclusive and rare timepieces from Patek Philippe in the modern era. Fitted with a 38 mm 18K white gold case, this annual calendar featuring day, date, month, moon phase and 24-hour indication comes with a glossy black dial and a matte black alligator strap. A perfect symphony to commemorate such an important partnership. To make things even more special, its black dial is double-signed by Patek Philippe and Tiffany & Co. featuring applied white gold classic Breguet numerals and a pearled recessed minute track, making this watch a true classic in all the sense of the word.
