Patek Philippe Annual Calendar 36mm Tiffany & Co 150th Anniversary Yellow Gold 5150

Created to commemorate the 150th anniversary of the historic partnership between Patek Philippe and Tiffany & Co., this exceptional Annual Calendar Ref. 5150 is a celebration of heritage and horological artistry. The watch is housed in a 36mm 18K yellow gold case, complemented by a fixed 18K yellow gold bezel. Its refined silver dial is adorned with gold index hour markers, offering a timeless and harmonious aesthetic. Powered by a Swiss automatic movement, the timepiece features hours, minutes, seconds, day, date, annual calendar, and moonphase complications. Additional highlights include a scratch-resistant sapphire crystal, a black leather strap secured by an 18K yellow gold pin buckle, and a solid 18K yellow gold case back.

It features an officer-style (hunter) hinged case back that opens to reveal a sapphire crystal exhibition window. This thoughtful design allows the wearer to admire the mechanical movement within, while preserving the classic appearance of a traditional solid gold case when closed. Exquisitely engraved with the Tiffany & Co. flagship store motif and the dates “1851–2001,” marking this significant anniversary.

Offered with box, this rare commemorative edition stands as a distinguished tribute to one of watchmaking’s most celebrated partnerships.
