In addition to the rather bold Marine version showed in 2016, collector can now opt for a subtler version of the Ulysse Nardin Classic Sonata, with a more classical dial. No more texture on the dial, no more triangular indexes, no more opening over the governor and no more luminous hands. wdfreplica This 2017 version of the Sonata sticks to more elegant codes, with baton indexes, a plain dial and leaf hands. Yet, the case remains large at 44mm, with quite some pushers and crowns But that s what you need to properly use this complex and rather unique piece of high-end watchmaking.
