The Venetian glass is done with silicium.

It is intended to be the first member of a family of movements incorporating both the DIAMonSIL escapement and an adjustable oscillator fitted with a silicium hairspring.

This oscillator, patented in 2007, was introduced to the market in the Sonata Silicium in March 2008.

“We were a precursor in 2001 with the use of silicium in our movements starting with the Freak timepiece,” Ms. Hurni said.

“The timepiece blends traditional enameling on the dial, and silicium in the heart of the mechanism,” Susanne Hurni, the chief marketing officer for Ulysse Nardin, said by telephone from the company’s headquarters in Le Locle, Switzerland.
