For 2010, Vacheron Constantin presents the Patrimony Traditionnelle “Calibre 2253” watch in the Collection Excellence Platine. 
This model features a major astronomical complication in terms of technical application. 
Entirely constructed by Vacheron Constantin’s engineering department and developed over several thousands of hours, the new Calibre 2253 provides information derived from Earth’s orbit around the sun, notably a perpetual calendar, the equation of time and the times of sunrise and sunset. 
It has a tourbillon escapement as well.
