The Vintage Wrist Watch Company has dated this piece to the 1920s.
The watch measures 50mm diameter excluding the 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.

Overall the case is in good condition, just a slight indentation to the back and some surface marking. The engine turned detail is still nice and crisp.
The acrylic lens has a couple of light marks but barely noticeable to the naked eye.

The dial is signed with the name of the original retailers of the watch, Kendal & Dent. It is in very nice condition.
Kendal & Dent were very well known watch makers and they also supplied ships' chronometers for the Admiralty. In later years, they bought in Swiss pocket watches for retail, such as the one we have here.
The watch will be sent in a new presentation box.
