Metiers d’Art Les Aerostiers 18K white gold watch on alligator skin strap, Vacheron Constantin

There’s a romantic tale of wanderlust behind this limited edition collection. Each of the five dial designs pays homage to an iconic hot air balloon ride that took place in France between 1783 and 1785. Entirely hand-engraved and microsculpted with gold, each dial also comes complete with intricate reliefs of human and animal figures, and takes artisans up to three weeks to complete.
