The Vintage Wrist Watch Company has dated this piece to the 1940s.
The watch has a Swiss 15-jewel hand-winding movement which is working nicely. The movement is calibre 364K which is a Cyma calibre.
From a collector’s point of view, both the British and Swiss made J W Benson movements are desirable and comparable in quality.

The watch measures 22mm wide excluding the winding crown and 32mm high excluding the lugs, it would suit a slimmer wrist. The case is 9 carat gold and there are hallmarks inside the case back for Birmingham 1949 together with a case maker's mark for Aaron Dennison, a prolific manufacturer of cases for various watch manufacturers. The inner back is also signed with the J W Benson name. The case is in good condition, as is the lens.

The signed dial is in its original finish with original handsomely shaped hands, a subsidiary seconds dial and an outer minute track. There is a little marking to the dial but overall very acceptable for a 1940s piece.
A new leather strap has been fitted.
The watch comes in its J W Benson presentation box.
