To prove that its Celestia Astronomical Grand Complication 3600 and the Symphonia Grande Sonnerie 1860 wristwatches weren't a pair of flukes, Vacheron Constantin has released its latest bit of haute horologie, Les Cabinotiers minute repeater tourbillon sky chart. A product of the manufacturer's Les Cabinotiers department, the dress timepiece sports a minute repeater function and localized sky chart on the reverse.
