The Vintage Wrist Watch Company has dated this piece to the 1920s.
The watch has a signed Swiss 15-jewel Vertex stem-winding movement which is working nicely. The movement is protected by an inner hinged cover which has light marking.

The watch measures 49mm diameter excluding the winding stem and the loop. The case is silver and there are hallmarks inside both of the back covers for Birmingham 1923 with a case maker’s mark for Aaron Dennison, a Birmingham based case manufacturer who supplied cases to many watch manufacturers. The case is in good condition, just a few small marks to the hinged case back.

The glass lens has light marks across it but is very acceptable.
The watch comes with a single chain, 31cm long including the T-bar and the clasp. Each of the links on the chain has the lion silver mark although quite rubbed. The T-bar is a later replacement.
Also included is a 1902 silver fob.
The watch and chain come in a new presentation box.
