The most captivating aspect of the Les Métiers d’Art Les Aérostiers collection isn't so much the time display as the skill and technique required to produce the remarkable dials of these limited editions (five each of the five designs). Precise reproductions of historic drawings, they depict hot-air balloons that took to the skies in France between 1783 and 1785. Each dial requires a combination of artistic crafts, such as classic engraving, pounced ornament engraving and plique-à-jour enamelling, executed with astonishing finesse and precision. Beneath these exquisite scenes, Vacheron Constantin has chosen one of its own movements to discreetly indicate hours, minutes, day and date on discs whose colour matches that of the dial.
