Ulysse Nardin has released several new Marine Chronometer models for 2012. The particular model you see here is a limited edition piece with a rose gold case and enamel dial.  I have included a lot of photos depicting the making of the enamel dials, as well as a closer look at some of Ulysse Nardin’s patened silicon component technology.  The watch is powered by Ulysse Nardin’s UN-118 caliber, first introduced in 2011 and featuring several of UN’s silicon based innovations such as the DiamonSil (silicon treated with a thin layer of diamond coating that not only eliminates the need for lubrication, but also significantly increases the part’s durability) and silicon hairspring — see Video below.   As well, the Marine Chronmeter case is slightly expanded to 45mm and has a new rubber-covered crown design.  The enamel dial is beautifully handcrafted by Donzé Cadrans, a world-recognized enamel-dial specialist that is owned by Ulysse Nardin.  As I say this is the limited edition piece, but I have included photos of the other models below as well.
