OMEGA desk clock purchased while living in the United States. I was told it was a very rare item. I am selling it because I am organizing my belongings due to a move. Size: 7.5 Set the time with the crown on top, and it is manually wound. I have confirmed that it works. There was no error after 9 hours since winding it. Due to its antique nature, it is not suitable for those who are sensitive to such things.
