The Photoret was designed by W.K.L. Dickson and Herman Casler. Its shape resembles a pocket watch but in use it was held upright. Some sources give the picture shape as hexagonal. On this example it is square with each corner cut off giving a very irregular octagon.

This example has the patent numbers on the back of the case, others have the patent dates on the front. Some models have the words "Time stop" around the B setting pin hole, this example does not.
