A shape within a shape, the iconic cushion case of the orginial Vacheron Constantin chronograph watch from 1928 has been reinvented for the new Harmony collection. A 37mm white gold case is set with 88 brilliant-cut diamonds on the bezel. Housing a opaline silver-toned dial, this is a dual time ladies' watch with a fresh take on the complication. Rather than having a traditional 24-hour hand, the dual time fuction is indicated in a gold-rimmed, sunken 12-hour sub-dial at 4 o'clock and day/night indicator at 7 o'clock. Turn the watch over and the first Vacheron Constantin in-house made chronograph movement can be admired. The automatic movement, calibre 2460DT, has a beautifully engraved oscillating weight. Presented on a pale blue alligator leather strap, this watch is limited to 500 models.
