Summary
Zeiss Ikon Diaphot Exposure Meter. This has the look of a thin pocket watch with a silver coloured edge and handle. This is an extinction meter, on one side is a view finder orifice through which one looks to rotate the disc and select the correct exposure. The correct exposure is when the view can barely be seen. Above the viewfinder is the Zeiss Ikon embossed logo in black and embossed and highlighted in silver "Germany". On the other side is a glass screen beneath which there is a black screen with a pentagram symbol central. There are two cut aways. The small one shows a graded shading and a black spot when rotated. The larger cut away has a panel showing apertures against which a disc reveals exposure times when the the disc is rotated.
