The Vintage Wrist Watch Company has dated this piece to the 1940s.
The watch measures 29mm wide excluding the winding crown and 29mm high excluding the lugs. The case is 9 carat gold and there are hallmarks inside the case back for Chester 1940. There are some fairly small indentations to the case, front and back.

The lens is in good order.
The dial is in its original finish. It has light marking but overall is very acceptable for a watch of its age. Handsome diamond hands (one is a slightly different colour), subsidiary seconds dial and an outer minute track.
A new dark brown leather strap has been fitted.
