I would tread carefully on this if I were you. The Oris name has been around for a long time. The only similarity between the Oris of 60 years ago and the Oris of today is the name. Oris disappeared from the market for a number of years, re-appearing having morphed into an upmarket, mid-range watch of vastly better quality than the earlier ones. Simply put, I would classify early Oris watches as " cheap" watches! I think the subject watch is one of those. If you can take a picture of what is inside the case and get back to us, we'll have a better idea.
