The material revolution continues. With the Sonata Silicium Limited Edition, Ulysse Nardin demonstrates the versatile use of silicium in watch making, including the production of micro precision components for our watch movements and for aesthetic use in the manufacture of watch dials.

The dial of the Sonata Silicium is cut out of a silicium wafer in its striking natural color; so too is the logo inlay on the winding rotor visible through the exhibition sapphire back of the case.

The movement runs with a 28’800 oscillator and an anchor escapement etched out of silicium. This escapement is the result of a research program which Association Suisse pour la Recherche Horlogère - Swiss Association for Horological Research conducted and in which Ulysse Nardin participated. Both the anchor and escapement wheel are manufactured of silicium.



The Sonata Silicium is based on the technical movement features of the Sonata Cathedral Dual Time including the novel alarm setting with a countdown indicator and the dual time system with the instant time zone adjustor featured in many Ulysse Nardin watches.

This patented dual time function permits time zone adjustments forward and backward by simply pressing the pushers plus (+) or minus (-) to change the position of the hour hand. The original home time (reference time) stays displayed while the date, the alarm and countdown adjust automatically when a time zone adjustment is made.

The melodic chiming of the Alarm is based on a novel 24-hours mechanism which allows setting the Alarm 24 Hours ahead for 7:30 pm the same day or 7:30 am the next day.

The Limited Edition Sonata Silicium limited to 500 pieces each in 18 ct white and rose gold.
