160 years is a mighty long time to be making watches, and Eterna has undertaken the celebration of this milestone with some very beautiful and intriguing pieces.  One of them being the Skeleton 1856. 

Named for the year of their founding, the Skeleton 1856 is (as you might have guessed by the name) a skeleton watch.  The movement itself provides the basis for the dial.

And as with any good skeleton watch, the movement can be viewed from the back as well.

The movement in question is Eterna's 3902 M, this is the dial side.

And this is what is visible through the sapphire crystal on the back of the case.  It is manual winding and boasts a very impressive power reserve of 65 hours.

The watch itself measures a respectable 42 mm in diameter, and is secured with a braided leather strap.
