Notes

Ref. 6378 Among the ?classics? of Vacheron Constantin, Ref. 6378 is one of its great successes. With a self-winding movement, gold-edged rotor with ruby roller bearings, calendar, and a water-resistant case, it is representative of the best Swiss wristwatches of the 1960s. Those in white gold were only produced in limited series.
