This is a gorgeous white gold Patek Philippe Calatrava reference 570, circa 1958. The original silvered dial with hard enamel signature is pristine with applied markers and 60 seconds outer tracking. The 18kt white gold case is superb. This beauty is powered by a caliber 27SC 18 jewel manual wind movement. An Archive from Patek Philippe is on order and will accompany this lovely vintage Patek Calatrava. A brand new Patek Philippe strap and Patek tang buckle comes with the watch as well.
