The Vacheron Constantin Historiques Triple Date Moonphase (Reference 37150) is a highly collectible luxury timepiece crafted by the world's oldest watchmaker in continuous operation. This beautiful watch was released in the 1990s as a modern tribute to the legendary, highly complicated mid-century watches of the 1950s.
