Introduced in honour of the 260th anniversary of Vacheron Constantin in 2015, the reference 57260 is the result of 8 years of research and development at the request of an anonymous collector, resulting in an entirely original creation exhibiting a total of 57 complications, several of which unique and new. It features three distinct types of perpetual calendars (Gregorian, Hebraic, Business), a rattrapante chronograph with separated seconds hands and several chiming functions including a repeater, sonnerie and alarm, and a triple-axis tourbillon. In addition, it features several astronomic functions like indications for the seasons, equinoxes and solstices, a sky chart (set for New York, perhaps revealing its owners location), sidereal time, sunrise and sunset and more.
