Vacheron Constantin 2260

A mechanical hand-wound tourbillon movement supplying an exceptional 14-day (336 hours) power reserve. In addition to the tourbillon coupled with small seconds at 6 o'clock along with slightly off-centred hours and minutes functions, it also features a power-reserve display on a 280° sector. To guarantee the 14-day power reserve, caliber 2260 is equipped with four barrels stacked in pairs, interconnected and discharging simultaneously, yet four times slower than a single barrel. The architecture of the 231-part movement features two large bridges. The tourbillon carriage, inspired by the Maltese Cross, is a showcase for exceptional finishing. The tourbillon bar alone takes over 11 hours of hand craftsmanship to complete.
