The Vintage Wrist Watch Company has dated this piece to the 1960s.
The movement is signed with the Omega name and also the serial number 20,159,537 which dates it back to 1963.

The watch measures 32mm diameter excluding the winding crown and the lugs. The case is gold plated (20 microns rather than the thinner 10 microns) and the condition is good with just the odd mark. The winding crown has the Omega logo.

The stainless steel snap-on case back has the Omega logo inside together with the case reference 103.001-63-SC which confirms it is also 1963 and the correct date for the movement.
The lens is in good condition.

The dial has some minor marking. The hour and minute hands appear to be the originals. There is also a centre seconds hand and outer minute markers.
A new brown leather strap has been fitted, with a vintage Omega buckle, and it sets the watch off handsomely.
