Hey gang,
I started a thread yesterday about this watch and today was able to carefully open the case. The photos are from inside the case and the movement, as well as some of the outside features. I don't see any serial number on the movement, and believe the serial number on the case may or may not have anything to do with the movement. I don't know anything about ZETA, so I would welcome any education. Not looking for a value necessarily, but more interested in the history. Thanks.
