In the 1950s, a young visionary named Hans-Ulrich Klingenberg embarked on a mission to produce watches of timeless beauty and impeccable quality.
To realize this dream, he displayed extraordinary ingenuity and tenacity.
One of his early breakthroughs was developing and patenting a revolutionary vacuum system in a monolithic watch case.
This innovation ensured complete resistance to water, air, humidity, and dust—the greatest enemies of mechanical movements.
HISTORY

Vacuum Test
“Otto von Guericke”
Magdeburg, 1660
In the middle of the XVII century, Torricelli and Pascal develop the theory of the vacuum.
Otto von Guericke makes the first vacuum pump. He demonstrates the efficiency of this pump with the aid of horses at Magdeburg.
This print inspired the creation of the vacuum logo.
