The Vintage Wrist Watch Company has dated this piece to the 1950s.
The watch has a Swiss 17-jewel hand-winding movement which is working nicely. In the photo of the movement, there appears to be a couple of empty holes... however, there should not be screws because the movement is held in place by the fitted case back.
The case is 9 carat gold and there are hallmarks inside the case back for Birmingham 1954, together with the J W Benson mark and also the case maker's mark for Aaron Dennison, a prolific case maker who supplied various watch manufacturers. The shaped lugs are a very stylish feature, they give the watch a very dapper appearance. The case is in good condition, just a couple of very minor “dings” to the back but nothing serious at all.

The lens is in good condition.
The signed dial has some freckling as shown in the photos. Feuille shaped hands, a subsidiary seconds dial and outer minute markers.
A new leather strap has been fitted.
The watch comes in a Benson presentation box... the outside of the box is tatty and has lost some of the outer covering.
