Ulysse Nardin " Vivaldi ".
The first " music box watch " by Ulysse Nardin was the " Stranger ", followed by the Vivaldi.
Another surprising creation by Ulysse Nardin...
Two issues for me. The first one, the date, which was not mandatory, in my opinion.
The second is that this watch doesn't sound very loud. It is quite discreet, alas.
But the concept is great.
