The Harmony mono-pusher chronograph is one of the seven models of the Harmony Collection produced to celebrate the 260th anniversary of Vacheron Constantin in 2015. Measuring an impressive 42 mm, it was made in a numbered limited edition of 260 examples in pink gold and inspired by an historic Vacheron Constantin doctor’s chronograph of 1928. The new caliber 3300 movement is the result of seven years of development, giving a power reserve of 65 hours and finished with hand-engraving. According to research, the present watch is only the second example of this model to appear at auction.
