百達翡麗，精細及非常罕有，18k白金自動上弦腕錶，型號3415，1960年製

Reference 3415 is one of Patek Philippe's few models made with the legendary self-winding caliber 12-600 AT movement, featuring the iconic double Patek Philippe crown and the classical design iconography that the manufacture utilised throughout the 1960’s and 1970’s. Produced only in 1959 and 1960, the present watch appears to be only the second example to appear in public, the first of which was offered at Christie’s November 2005 Geneva sale and sold for CHF 98,400.
