The Vintage Wrist Watch Company has dated this piece to the 1920s.
The watch has a Swiss hand-winding movement, believed to be by Langendorf, which is working nicely.
The case is silver and there are hallmarks inside the case back for Glasgow 1929 with a sponsor’s mark for George Stockwell.

From 1 June 1907, Stockwells acted as assay agents, facilitating the import into Britain of foreign gold and silver items which had to be assayed and hallmarked in a UK assay office before being released for retail.

The case is in lovely condition, and it is a good wearable size.
The lens is in good condition (some reflection showing in the photos).
The dial has light marking across it, and a couple of faint hairlines but they are difficult to see with the naked eye.
A new leather strap has been fitted.
The watch comes in a new presentation box.
