The Vintage Wrist Watch Company has dated this piece to the 1930s.
The watch has a Swiss stem-winding movement which is working nicely. The movement has been identified as a Vertex Revue. The movement is protected by an inner hinged cover which has general light surface scratches.
The watch measures 50mm diameter excluding the winding stem and the loop.
The case is in good condition with just light surface marks.

The front cover has a small central lens surrounded by enamel filled Roman numerals some of the enamel has come out over the years but not too detrimental.
The winding crown pushes in to open the front cover.

Inside, there is an acrylic lens which is in good condition (there are some reflections showing in the photos).
The dial is in good condition with original 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.
