Vacheron Constantin was founded in 1755 by Jean-Marc Vacheron, an independent watchmaker in Geneva, Switzerland.He was a close friend of leading Enlightenment philosophers Jean-Jacques Rousseau and Voltaire due to their common interests in philosophy, science and watchmaking. In 1770, Vacheron's company created the world's first horological complication, and nine years later he designed the first engine-turned dials. The son of Jean-Marc Vacheron, Abraham Vacheron, took over the family business in 1785.
