The 35mm 18KT yellow gold round case embodies classic elegance, while the silver dial proudly bears the Tiffany & Co. signature, complemented by gold hour markers for a refined aesthetic. A sub-seconds dial at 6 o’clock adds to its vintage charm. Powered by the manual-wind Caliber 12-120 movement with 18 jewels, this watch exemplifies Patek Philippe’s timeless craftsmanship. Case No. 654572 further authenticates this exceptional piece.
