Vacheron Constantin Solaria

Twenty years after Vacheron Constantin celebrated its 250th anniversary with the 16-function Tour de l’Ile (named after the Genevoise island where founder Jean-Marc Vacheron set up a workshop in 1755), the company rings it its 270th year with the Les Cabinotiers Solaria Ultra Grand Complication, a 45-millimeter-diameter wristwatch boasting 41 complications — including five solar and celestial indications. The split seconds hands of its rear-side stopwatch function even double as a means of knowing when your chosen star (selected from the 13 zodiac constellations on the watch’s dial) will be visible from Earth.
