The Vintage Wrist Watch Company has dated this piece to the 1890s.
The watch has key-wound movement which is working nicely.
The patent was for an integrated dust ring which also acted as a movement carrier. The movement is protected by an inner hinged cover.

The watch measures 51mm diameter excluding the stem and the loop. The case is silver and there are hallmarks inside the case backs for London 1892 with a maker's mark for J W Benson. A previous owner's name has also been engraved into the inner case back, A Haymany. Overall the case is in good condition with just some unevenness to the back.
The watch has a glass lens which is in good condition, as is the signed enamel dial.
The watch comes in a new presentation box.
