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.
Introduced in 2015, caliber 3750 is the result of over 8 years of development and consists of over 2800 parts, including 242 jewels and three column wheels. Among its most notable features is its Hebraic Perpetual Calendar that is shown alongside the regular (Gregorian) calendar and business calendar. Due to the long-term changing cycles of the Hebraic calendar and its difference with the Gregorian calendar, its implementation in a watch was considered impossible until the unveiling of caliber 3750. This calendar includes a year indicator and and a Yom Kippur sector.
Other notable features include the double retrograde rattrapante chronograph with two seconds hands moving in sync, yet not with one atop of the other; a night mode for the sonnerie, a chiming alarm, an ISO 8601 business calendar, a triple-axis 'armillary sphere' tourbillon and much more.
