The Marine Chronometer Series

From Ulysse Nardin

Limited to 99 pieces. 

Ulysse Nardin's Caliber UN-118 COSC chronometer is housed in a 45 mm stainless steel case that has been treated with what UN refers to as a "Blaktop" coating.

A point of interest in the movement is that the escapement is UN's patented DIAMonSIL, the oscillator features a patented inertial balance wheel l 10 with a silicium hairspring.  It boasts 60 hours of power reserve. 

Hours, minutes, seconds, date (at 6 o'clock) and power reserve (at 12 o'clock).  Sapphire crystal front, display back.  The strap is a combination of rubber and titanium that have also been "treated" with the "Blaktop" coating.
