The Vintage Wrist Watch Company has dated this piece to the 1960s.
The movement is signed Omega Watch Co, Swiss and it has the serial number 17,876,633 which dates it back to 1960.

The watch measures 33mm diameter excluding the winding crown and the lugs. The case is stainless steel and the condition of the front and sides is good. There are some scratches to the case back.
