Vacheron Constantin is the world's oldest manufacturer of fine watches.

Founded in 1755, the company has been witness to the evolution of luxury watchmaking. It has excelled through out the years by never wavering from the very highest standards of excellence and style.

As one of the world's most venerable watch makers, Vacheron Constantin has played an important role in offering innovation and technology to the industry.

Among the company's special features: 

 In 1770, the company produced its first complication watches.

 Vacheron Constantin produced the first engine-turned dials and the first ever six quarter-repeater watches, striking the hours and the quarters upon request.

 In 1839, supervisor of manufacturing operations, Georges-Auguste Leschot, standardized movements into calibers, an accomplishment that revolutionized the art of watchmaking.

 Leschot later went on to pioneer additional technology, such as creating the pantographic device that allowed mechanical reproduction of certain watch parts.

The To-and-Fro calendar watch offers a to-and-fro, 31 day calendar mechanism which is visible from both the back and front of the case. This watch design has become one of the company's most popular lines.

1839 Vacheron Constantin manufacturing supervisor, Georges-Auguste Leschot invents standardized movements called "calibers", changing watchmaking forever.
