The Vintage Wrist Watch Company has dated this piece to the 1910s.
The watch has a seven jewel stem-winding movement which is working nicely.
The movement is protected by an inner hinged cover.

The watch measures 50mm diameter excluding the winding stem and loop. The case is silver and there are hallmarks inside all three covers for Birmingham 1913 with a case maker's mark for Aaron Dennison of the Dennison Watch Case Company, a prolific manufacturer of watch cases for various watch companies.

The watch has a small lens to the front which is surrounded by dark blue enamel filled Roman numerals. There is a small chip to the small lens.
The case has three small knocks to the central section and a series of small "dings" to the back.

The winding crown pushes in to open the front cover. Inside, there is an acrylic lens which is in good condition.
The white enamel dial is signed Coventry Astral. There is a short hairline crack by number 5 but it is faint. Blued steel hands, a subsidiary seconds dial and an outer minute track.

Henry Williamson founded his business in 1865 and became an increasingly successful and important wholesaler and retailer. The business increased in size as they acquired the English business of Charles Hutton Errington of Coventry in 1895 and the remnants of the English Watch Company in 1897. H Williamson's company was taken over by Smiths in the early 1930s.
The watch will be sent in a new presentation box.
