Produced during 1940 until 1948, the ref. 1536 were cased in yellow and pink gold and were crafted by Geneva master casemaker Wenger and powered by the 12’’’120 indirect sweep centre seconds movement. They were fitted with Stern dials that feature hard-raised enamel signatures and scales, baton hands, and blued steel seconds hand. With less than a handful of pink on pink examples ever surfaced the market (total of 5 examples with one double signed example), the present example bears an attractive two-tone pink dial with strong raised enamel long signature and scales. The four oversized conical lugs anchors the timepiece spectacularly on the wrist. The stamped hallmark on the caseback remains deep and intact, its movement number stamped on the snapped caseback is still visible. Confirmed by the Patek Philippe Extract from the Archives, this gem is from 1949 and further sold on the last day of February in 1950. Beautifully preserved, this is a chance for collectors to own a piece of Patek Philippe’s history that documents their ability to break boundaries.
