The Vintage Wrist Watch Company has dated this piece to the 1920s.
The movement is signed Thomas Russell & Son and is protected by an inner hinged cover.

The watch measures 50mm diameter excluding the winding stem and the loop. The case was made by the Illinois Watch Case Company and it is also signed with the Thomas Russell name. The case has three small indentations to the back and some rubbing to the finish but overall is very acceptable for a 1920s piece - the patterned edge is a nice feature of this case.
The plastic lens has light marks.
The white dial is also signed Thomas Russell & Son. It has blued steel hands, a subsidiary seconds dial and an outer minute track.
