Up for sale only is my Eterna 160th Anniversary skeleton watch from 2016. I bought this from the original owner on Ebay a couple years ago and have not worn it much. It runs great. You will find scratches on the case from being worn, but the sapphire crystals are clean. The original braided black leather strap has been worn by the previous owner, but I never used it since it was too stiff for my taste and I am a bracelet guy. So you will also get a brushed and tapered 20mm strapcode superfine mesh bracelet. Wears like a 40mm. Very comfortable case design to wear. No box or papers.

There were 3 versions of this watch made and this is number 116 of 160 (so 480 watches were made in total). Original retail price was $4,950. Here are some stock photos (my version is the one on the left), and my pics are below these.

Here are the specs:

41.7mm case
48.8mm lug tip to lug tip
10.8mm height
20mm lug width
50 meters
Push pull crown hacks the hand wind 3902M movement (based off of Eterna's calibre 39)
65 hours of power reserve
Sapphire crystals front and back
