Watch of the Week: Vacheron Constantin Métiers d’Art Les Aérostiers

Our watch of the week is actually a series of watches, as Vacheron Constantin took everybody's breath away last SIHH by introducing five versions of the Métiers d'Art Les Aérostiers. These watches pay tribute to the early days of aviation when hot air balloons where the first means for humankind to explore the earth from above.
