Calibre 2260, a mechanical hand-wound tourbillon movement supplying an exceptional 14-day 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. A “dragging” or “trailing” hand shows the remaining energy on a 280° sector. This surface area, which is larger than on classic indicators, enables a precise division of the 14 days, themselves divided into two 12-hour slices and thus enhancing the readability of the power reserve.
To guarantee the 14-day power reserve, Vacheron Constantin Calibre 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 Calibre 2260 features two large bridges. The movement finishing and notably the Côtes de Genève motif find magnificent scope for expression in these generous dimensions. The tourbillon carriage, inspired by the Maltese Cross, is a showcase for the exceptional finishing of the parts featuring a number of naturally handbevelled interior angles. The tourbillon bar along takes over 11 hours of hand craftsmanship to round off.
