I am collecting German novelty eye clocks. The type that the right eye is the hour and the left eye is the minute. The hours are notched around the eye socket of the right eye and the minutes are notched on the left side, as the eye revolves around a hash marks on the eye balls points to the appropriate hours and minutes. The majority of the ones that I have and have seen were made by J. Oswald, Freiburg, Germany. I have three that are marked Sinn, Frankfurt, Germany, and I have one that is not marked except for a six digit number that could possibly be a third maker. I am surprised at the lack of information that is available regarding these interesting and unique clocks and the companies that produced them. I have found one page references to them in two books. Thanks to fellow member Mr. Douglas Stevenson who directed me to the book “Price Guide to Collectible Clocks 1840-1940" by Alan and Rita Shenton on page 256 there is a brief description and a picture of four models available. In the book “Pastime Telling Time From 1879 to 1969" there is one picture of a dog that was produced and a very brief mention of J. Oswald. These novelty clocks seem very scarce in my area of Michigan and the few that I was able to find even at clocks shows were the common Scottie dog and Pekinese dog (these are being reproduced by the Chinese). Since I have become hooked on E-Bay I am surprised and somewhat amazed at the variety that were produced, very tall to miniature shelf models of human forms as well as animals, and wall hanging plaques. Is anyone aware of a more detailed history of J. Oswald or of any publications that show a more complete line of novelty clocks available?
