The Vintage Wrist Watch Company has dated this piece to the 1920s.
The movement is signed Craftsman. This brand name was registered by at least five watch companies, and it was probably the case that one of these companies bought movements in from Cyma for their Craftsman branded watches. Originally there would have been an inner cover over the movement but this has been removed over the years.

The watch measures 50mm diameter excluding the winding stem and the loop. The case is gold plated. There are a couple of patches of wear, including a 6mm patch to the front cover. There is also an indentation to the front cover although fairly shallow.

The winding crown pushes in to open the front cover. Inside there is an acrylic lens which is in good condition.
The signed dial is in lovely condition and has blued steel hands, a subsidiary seconds dial and an outer minute track.
The watch will be sent in a new presentation box.
