Marine chronometers are part of Ulysse Nardin’s identity: the company was famous for them in the 19th century. It should come as no surprise, then, that the brand selected its Marine Chronometer wristwatch, which was named in honor of the company’s ships chronometers, to be among the first timepieces to receive the new caliber UN-118 manufacture movement.
The Marine Chronometer Manufacture has a 45-mm case (larger than the existing Marine Chronometer case) and a new crown designed for easy handling. The dial is handcrafted enamel, produced by Donzé Cadrans, the newest member of the Ulysse Nardin group of companies. (Click on photos for larger images.)
The escapement in Caliber UN- 118, the result of a collaboration between Ulysse Nardin and the Swiss firm Sigatec, is made of a material called Diamonsil, which consists of synthetic diamond grown on a silicon base. The movement also features the company’s own oscillator and its patented hairspring.
The Marine Chronometer Manufacture will be available in three versions: a limited edition of 350 pieces in rose gold priced at $38,600 on a strap; an unlimited two-tone edition with titanium case with gold bezel and gold crown priced at $17,800 on a strap; and a stainless-steel/titanium case priced at $10,400 on a strap. Matching bracelets are also available.
