The Vintage Wrist Watch Company has dated this piece to the 1930s.
The watch has a stem-winding movement, calibre 40.6 T2.15P, which is working nicely.
.. this calibre of movement was made from 1923 until 1936. The movement is protected by an inner hinged cover upon which are images of trade medals won by Omega.

The watch measures 49mm diameter excluding the winding stem and the loop. The case is 800 silver and there are Continental hallmarks inside the case backs, along with the early Omega logo. As well as being silver, there is a rose gold wash around the edge of the watch, this is known as a galonne case. There is some rubbing to the rose gold wash on the back of the watch but not too detrimental. The back of the watch has a cartouche with the name Carl-Uno.
The acrylic lens is in good condition.
The signed white enamelled dial has a hairline crack but it is quite faint.
The watch will be sent in a new presentation box.
