The Vintage Wrist Watch Company has dated this piece to the 1950s.
The watch has a bumper automatic movement, calibre 342, which is working nicely.
Later automatic watches have the fully rotational rotor.

The movement is fully signed and the serial number 12,066,819 dates it back to 1950.
The watch measures 34mm diameter excluding the winding crown and the lugs. The case is stainless steel and it is in good condition, just light surface marks but nothing serious at all. The winding crown is signed with the Omega logo. The inside of the screw-on case back has the Omega triangular mark together with the case reference 2576-11 which is correct for the 342 movement.

The lens is in good condtion.
The signed dial has been professionally re-finished, a long time ago, and it now has a really good look to it. Original hands (with a little marking), a subsidiary seconds dial and outer minute markers.
A new sports strap has been fitted but the buckle with the Omega symbol has been retained.
The watch will be sent in a later Omega presentation box.
