From the very secret and private safe of Nicholas G. Hayek, Mr. SWATCH himself, and never before seen "in public," two extremely precious prototypes of the most successful plastic watch in the world… made of pure gold and platinum!
In order to test the concept of engineering and construction and to
develop the best possible technical solution, the beginning of Swatch took
place at a watchmaker's table. Therefore, these two perfectly working
masterpieces of contemporary watchmaking represent the ideal bridge
between "the old and the new" way of looking at Switzerland's most
renowned industry. They mark the immaterial point separating "time before
Swatch" from "time after Swatch."
