SIHH 2012 - Vacheron Constantin offers a new interpretation of the stunning Tourbillon complication in keeping with the classic style and elegance inherent to this 100th anniversary of its Tonneau-shaped collection.
On the dial featuring pink gold hour-markers and Roman numerals for the 6 and 12 o’clock indications, the Tourbillon bearing the seconds hand finds its natural place, perfectly integrated within the new and refined lines of the Malte collection.
Its positioning at 6 o’clock calls for slightly offsetting the axis of the hour and minute hands.
The movement is a mechanical hand-wound Caliber 2795, comprising 246 parts, beating at a frequency of 2.5 Hz (18,000 vibrations/hour) and endowed with an almost two-day power reserve (45 hours).
This new tonneau-shaped movement – making a perfect fit with the case – is entirely developed and crafted by Vacheron Constantin.
The Tourbillon carriage is inspired by the brand’s signature Maltese cross, and magnificently showcases the exceptional level of finishing of each movement part, including a number of naturally hand-beveled interior angles.
