Good afternoon gentlemens, Hinrik, concerning your question I am not sure of my right concerning posting of images in books. The clock in your image is reproduced in Knirim, Konrad (2002): Milit?ruhren/Military timepieces, Verlag Peter Pomp, Bottrop-Essen page 287. Also a pic of the U 124 radio room is there to be seen: Message station of U 124: The oficer has a KM wrist watch, left at the wall is a small Junghans clock J30E with chromed bezel. Image below (Knirim collection): Submarine wall clock Junghans cal J30D with big dial and 8 days movement and the smaller version with Junghans J 30D Another pic of U 2518 radio room, page 281, shows the Kieninger & Obergfell wall watch near a 40 watt Lo 40K39 transmitter I think your watch is the Junghans J30D or a very similar version hope this helps best regards Alejandro Gomez Guerrero http://community.webshots.com/user/eaj1es (personal Uboat items collection)
