Ulysse Nardin Introduces its New In-house Designed Movement, the Caliber 118

Swiss luxury watch manufacturer Ulysse Nardin introduces its new Caliber 118 and confirms its leadership in the innovative use of avant-garde materials in the watch industry. Caliber 118 follows in the footsteps of Ulysse Nardin’s Caliber 66/67 Sonata, the first timepiece conceived and manufactured in house and Anniversary Caliber 160, but takes innovation in movement technology a further giant step forward. The escapement of Caliber 118 is produced in collaboration between Ulysse Nardin and Sigatec in Sion, Switzerland.

DIAMonSIL is a revolutionary alliance of silicium and man-made diamond. It is an extremely light but hard material that eliminates friction and removes the need for lubrication of the escapement – the watchmaker’s holy grail.

Sigatec is the only company in the world capable of producing high-precision components both in Silicium and DIAMonSIL; a nanotechnology which has taken many years to develop.

Caliber 118 will be the first member of a family of movements with an in-house produced and patented DIAMonSIL escapement together with the in-house-produced oscillator adjustable with four screws and fitted with a silicium 1.1.1 hairspring.

This oscillator, patented in 2007, was first put on the market in the Sonata Silicium in March 2008.The Caliber 118 also features a 60-hour power reserve and its own date-corrector, allowing forward and backward settings in seconds.
