Patek Philippe 5150J T150 Annual Calendar "Tiffany & Co." 18K Yellow Gold Silver Dial

Introduced in 2001 to celebrate the 150th anniversary of the Patek Philippe and Tiffany & Co. partnership, the Ref. 5150J “T150” is a restrained yet profoundly significant annual calendar wristwatch. Crafted in 18K yellow gold, the 36 mm officer‑style case opens via a hinged back to reveal the meticulously finished automatic Caliber 315/189, stamped with the Geneva Seal and enhanced with a moon‑phase display—an elegant evolution of Patek’s first annual calendar movement. The dial presents a rare silver tone, with day, date, and numeric month apertures arranged in a refined layout, while an oversized “T” at 12 o’clock and the Tiffany & Co. signature beneath the moon‑phase subtly underscore the collaboration. With only 150 pieces produced in yellow gold as part of a tri‑metal limited edition, this piece is exceptionally rare and steeped in both horological and cultural significance. Collectors prize its combination of technical innovation, historical commemoration, and aesthetic restraint. The movement’s 48‑hour power reserve, central seconds, and exquisite finishing further elevate its appeal. This is not merely a watch, but a wearable chapter in the storied legacy between two icons of luxury. Like New with Patek Philippe Tiffany & Co. box and photocopy papers.
