The Vintage Wrist Watch Company has dated this piece to the 1950s.
The watch has a calibre 410 hand-winding movement which is working nicely. The movement is signed Omega and the serial number 15,730,326 dates it back to around 1957. There is a difference in the finish between the bridges within the movement but further investigation has revealed that this is a common occurrence with the 410 so they may well have been manufactured this way (rather than a replacement bridge).
The watch itself measures 33.5mm diameter excluding the winding crown and the lugs. The case is stainless steel.
The winding crown has the Omega logo. The case back has a 1957 inscription on the outside and the Omega triangular stamp to the inside, along with the case reference 2759-9SC which is correct for the calibre 410.

The lens is in good condition.
The signed honeycomb dial has a little age related darkening. Dauphine shaped hands, subsidiary seconds dial and outer minute markers.
A new leather strap has been fitted.
The watch will be sent in a new presentation box.
