#CountdowntotheNewYear: This month in #NYC, this impressive Cartier Ecran Mystery clock fetched $564,500 – more than double its $200,000 high estimate. Produced only in the mid 1920’s, Cartier Ecran Mystery clocks are exceptionally rare, with possibly only 10 in existence. The ‘mystery’ refers to the hands, which appear to float on the dial with no connection to the movement. This stunning example is constructed of rock crystal, onyx, enamel, coral, and yellow gold with diamond set hands. #SothebysWatches #Cartier #sothebys2020wrapped
