The engravings in ((Birds of America», published by the American naturalist and artist J.J. Audubon (1785-185 1) last century, have provided Vacheron Constantin with the theme for a series of exceptional men’s watches. Each dial features a bird from the artist’s book reproduced in champlevé enamel by the talented Geneva enameller, Muriel Séchaud. There are ten different birds, each in a limited edition of ten. Adorned with gold hour markers, the enamelled dials are set in a 750 (18K) yellow gold case with a cover activated by a secret spring.
