The Vintage Wrist Watch Company has dated this piece to the 1910s.
The watch measures 44mm diameter excluding the winding stem and the loop.

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, as is the acrylic lens.
The dial has blued steel hands, a subsidiary seconds dial and outer minute markers. There are a couple of short hairlines radiating from the centre but they are faint.

The watch comes with a silver chain, 32cm long including the T-bar and the clasp. Each of the links on the chain have the lion silver mark, and the clasp has a date letter for 1912.
The watch and chain come in a new presentation box.
