Vacheron Constantin is a Swiss manufacturer of prestige watches and a brand of the Richemont group. It employs around 400 people worldwide, most of whom are based in the manufacturing plants in Geneva and Valle de Joux. Previous Vacheron Constantin owners include Napoleon Bonaparte, Pope Pius XI, the Duke of Windsor and Harry Truman. The company was founded in 1755 by Jean-Marc Vacheron, an independent watchmaker in Geneva, Switzerland. This makes it one of the oldest watch manufacturer in the world with an uninterrupted history. Besides being a young businessman, Vacheron was also a talented craftsman. In 1770 his company created the first complication, and nine years later he designed the first engine-turned dials. The son of Jean-Marc Vacheron, Abraham, took over the family business in 1785. During this period the company was able to survive the French Revolution.
