The Vintage Wrist Watch Company has dated this piece to the 1950s.
The watch has a 17-jewel calibre 351 bumper automatic movement.
Later automatic watches have the fully rotational rotor. The movement is fully signed and it has the serial number 12,717,894 which dates it back to 1950.

The inside of the screw-on case back has the Omega logo together with the case reference 2577-8 which is correct for the calibre 351 movement.
The watch measures 34mm diameter excluding the signed Omega winding crown and the lugs. The case is stainless steel and it is in lovely condition.

The lens has light marking but is very acceptable (some white reflection showing in the photos).
The signed dial is in its original finish with original hands and centre seconds hand. There is some age related darkening and light freckling, giving a nice even tropical finish.
A new leather strap has been fitted.
The watch comes in a new presentation box.
