Vacheron Constantin 2160

The first self-winding tourbillon movement developed by Vacheron Constantin. In addition to the elegance of its openworked carriage shaped like a Maltese cross, the emblem of the Manufacture, Caliber 2160 is distinguished by its incredible slimness: this ultra-thin 188-part movement endowed with an approximately 80-hour power reserve measures just 5.65 mm thick. Its relatively sedate frequency (2.5 Hz), along with its 22K gold peripheral oscillating weight, provide a chance to admire the steady beating of its mechanism. The bar of the tourbillon carriage is entirely hand-bevelled, a craftsmanship operation that takes almost 12 hours for this component alone.
