The Vintage Wrist Watch Company has dated this piece to the 1920s.
The watch has a Swiss stem-winding movement, by Revue, which is working nicely.

The watch measures 50mm diameter excluding the winding stem and the loop. The case is silver and there are hallmarks inside both of the case backs for Birmingham 1925, together with a case maker’s mark for Aaron Dennison, a prolific case maker and supplier to various watch makers. The case is in good condition, just a hint unevenness to the back, and a couple of marks where the loop has pressed into the case back.

The glass lens is in good condition with light marking, nothing too serious at all.
The dial is signed Kay’s Keyless “Challenge”. William Kay set up Kays of Worcester in 1890. Customers bought items from handbills in a folder and initially the goods on offer were limited to household items, jewellery, clocks and watches such as this one. The goods were bought in and labelled with the Kays name. Eventually William’s son Jack took over the running of the business. The company continued to expand and trade successfully, becoming one of Worcester’s largest employers.
The signed dial looks good to the naked eye. If viewed very closely, you can see several faint hairlines. Blued steel hands.
The watch comes in a new presentation box.
