At Ulysses Nardin, the revolution of materials continues, declining silicon in all its evolutions. Dial components of micro precision, spiral exclusive, oscillating, anchors or exhaust developed with the assistance of the ASRH (Swiss Association for Clock making Research): as many technical developments dedicated to the movement and the esthetics of this ultimate edition. A series limited, of 300 parts of each gold, equipped with an alarm to the sound of a gong of cathedral, programmable under 12 midnight.

       Mechanical movement with automatic reassembly, gauges UN-67, 28 ‘ 800 Alt/h, holds of walk of approximately 42 hours. Anchor and dart, just as plate and finger of impulse in only one part by ravage plasma out of silicon, spiral carried out in a silicon plate of orientation.

       With Sonata Silicon Limited Edition, manufacture Ulysses Nardin once again proves the potential of use of silicon for clock making industry. This material is used as much for the components of the movement of this single part as for the esthetics of the dial. A silicon wafer in its original color cuts the dial of Sonata Silicium. The logo is also encrusted on the rotor, visible through the open bottom. The lever escapement engraved in silicon makes it possible the beam to beat with 28 800 alternations/hour. This exhaust is the fruit of a research program that the ASRH (Swiss Association for Clock making Research) led. Ulysses Nardin by its taste of technical innovation was to take part in it. The anchor and the wheel of exhaust are all two out of silicon.

       The Inno Vision program of Ulysses Nardin presented in August 2007 developed 10 technological innovations. Three of these last consequently are introduced into a finished product and are marketed. The ravage plasma by the two faces which makes it possible to carry out the anchor and its dart only one part. The spiral one realized in a silicon plate of orientation 1.1.1 (patent deposited).
Sigatec, a company created by Mimotec and Ulysses Nardin, produces all the silicon components of this exceptional chronometer.

       The design features of the movement of Sonata Silicium watch remain similar to those of Sonata Cathedral Dual Time: the alarm clock with countdown and Dual system the “Time”. Such technical functionalities appear already in several models Ulysses Nardin. Dual system the “Time” makes it possible to pass from a time zone to the other while supporting on one of the push rods, this which corrects the standard time while preserving the hour of origin. All the other functions adapt automatically (date, alarm clock, countdown) when a change of hour is carried out.

       The harmonious stamp of the ringing (alarm) is dictated by the work of a cam 24 hours doubled of a cam of the minutes. This complementarily allows a precise daily release, which eliminates moreover the risk from confusion (between 07h35 and 19h35, for example). Sonata Silicium Limited Edition is limited to 500 gold coins pink and 500 gold coins gray.

       Movement: report automat, caliber UN-67, mother-of-pearl and its dart in a part by ravage plasma out of silicon, plate and the finger of impulse in a part by ravage plasma out of silicon, spiral carried out in a silicon plate of orientation 1.1.1 (patent deposited), 42h of reserve of walk.

       Functions like alarm clock with stamp and countdown, Dual system Time with changes off time zone, great date
       Box is made out off pink gold 18 carats gold white gold, 42mm off diameter, seals with anti-reflecting 30m, ice sapphire, bottom sapphire screwed, tight crown.
