Appears to be an automatic movement and matches up with other identical watches as having 17 jewels. When shaken the second hand does move and seems to be running more continuously as we shake it more. But we cannot get the back off to determine for sure. Regardless, you experts out there will know what it is. Because we can?t get the back off, we are selling as is. Price will be reflected. But it does seem to run so might just need a deep clean and (obviously) a new watch band. See photos and reach out with questions. This appears to be the ultra rare version. So cool to find at a recent estate sale. Will ship USPS with tracking to winning buyer
