Celestia Astronomical Grand Complication 3600 - Vacheron Constantin

The Fine Watchmaking firmament welcomes a bright new star: the unique twin-dial Celestia Astronomical Grand Complication 3600 combines astronomy and the watchmaking art in a celestial white gold composition. Twenty-three essentially astronomical complications appear on the front and back dials of the watch, providing a reading of time in three modes – civil, solar and sidereal – each driven by its own gear train. Embodying the height of technical sophistication, its new fully integrated 514-part caliber measures a mere 8.7 mm thick, while six barrels guarantee three full weeks of autonomy.
