The Vintage Wrist Watch Company has dated this piece to the 1950s.
The watch has a signed 17-jewel hand-winding movement, calibre 28, which is working nicely.

The watch measures 31mm diameter excluding the winding crown and the lugs. The case is 9 carat gold and there are two sets of hallmarks inside the case back, the first set is for Birmingham 1951, and the second for when the watch was exported to the Republic of Ireland.

There is a little discrepancy in the dates but this is perfectly feasible as production of watches ceased for many watch manufacturers during the second World War as concentrated on the war effort.
The case has minor marking and a little unevenness to the back but otherwise is in good condition. Plain winding crown.

The lens has a 2mm scratch but you have look carefully to see it.
The dial is in its original finish which has aged a little, and a little fading to the Omega name and logo. Feuille shaped hands.
The watch comes in a later Omega presentation box
