The Vintage Wrist Watch Company has dated this piece to the 1960s.
The watch has a 17-jewel hand-winding movement, calibre 269, which is working nicely. The movement is fully signed and the serial number dates it back to 1963.
The watch measures 33mm diameter excluding the winding crown and the facted lugs. The main body of the case is gold plated while the case back is stainless steel.
The inside of the case back has the Omega logo and the case reference 121.001-63

Plain winding crown.
The lens is in lovely condition.
The signed dial is in its original finish with original hands, a subsidiary seconds dial and outer minute markers. There is a little marking but not too detrimental.
A new leather strap has been fitted.
The watch comes in a later Omega presentation box. It does not quite close fully because of the newness of the strap.
