WHO OWNS SILICON HAIRSPRINGS

Long energy storage silicon hairspring

Not everyone is a fan of the modern silicon hairspring. Some wonder whether silicon has its place in a traditional mechanical watch. Others question the ability to restore movements with silicon components in the. . The use of silicon in the watch industry was pioneered by Ulysse Nardin (with Ludwig Oechslin & Pierre Gygax on the technical side), in particular inside the Freak. If the 2001. . 20 years after the original patent was filed and since it has now just expired (last Friday, to be precise), it will be interesting to see who will.
