I got this Junghans car clock with a J30 movement to prove that the J30 was derived from the J26 pocket watch movement.
Several variants are known of the J30
J30A - 8 day, automatic winding from 1929
J30B - 1 day board clock from 1935
J30C - 8 day board clock from 1936
J30D - 8 day car clock from 1937, main spring case from J44
J30BZ - 1 day board clock with chronograph from 1938
J30E - 8 day car clock with rewind click from 1940
This is a Junghans carwatch with a J30 movement. The watch has a diameter of 80 mm and can be mounted in a board.
