The Vintage Wrist Watch Company has dated this piece to the 1910s.
The watch has a Swiss hand-winding movement which is working nicely.
The watch measures 35mm diameter excluding the winding crown and the fixed wire lugs.

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 good condition for such a piece, there are some marks and a little unevenness in places, but overall very acceptable. The small button at 8 o'clock is pressed in to release the front cover. Inside, the lens is in good condition.
The dial has a couple of hairline cracks but they are faint.
A new leather strap has been fitted.
The watch will be sent in a new presentation box.
