The Vintage Wrist Watch Company has dated this piece to the 1910s.
The watch has a Swiss 15-jewel stem-winding movement which is working nicely.

The watch measures 50mm diameter excluding the winding stem and the loop. The case is hallmarked for London (import mark) 1919 with a sponsor’s mark for Louis Weill. The case is in lovely condition. The front has a small central lens surrounded by enamel filled numerals.

The winding crown pushes in to open the front cover.
Inside, there is an acrylic lens which is in lovely condition (some reflection showing in the photos).
The dial is in good condition, just a couple of minor marks but they are difficult to see with the naked eye. Blued steel hands including the special half hunter hour hand so that the time can be read when the front cover is closed.
The watch comes in a new presentation box.
