The Vintage Wrist Watch Company has dated this piece to the 1910s.
The watch has a Swiss 15-jewel stem-winding movement which is working nicely. The movement is protected by an inner hinged cover.
The watch measures 50mm diameter excluding the winding stem and the loop.
Dennisons were based in Birmingham, UK and manufactured cases for various watch makers. The case is in good condition, just a couple of small shallow indentations to the hinged back.

The glass lens has light marking around the edge at the bottom but you have to look quite carefully to see it.
The dial has a very faint short hairline, difficult to see with the naked eye. Otherwise it is in lovely condition with blued steel hands, a subsidiary seconds dial and an outer minute track.

The watch comes with a single silver chain, 28cm long including the T-bar and the clasp. The chain is not hallmarked but has tested as being silver. There is also a silver and enamel fob from the Bristol Federation of Boys Club, awarded in 1938 for cricket.
The watch and chain come in a new presentation box.
