| Ticka watch camera|
The Ticka watch camera was made in England by Houghtons, between c.1905 and 1914. The design is similar to the American Expo Watch camera from the Expo Camera Company - both designed by Swedish engineer Magnus Neill.
The Ticka uses a special 17.5mm roll film - loaded in cassettes - taking 25 16 x 22mm images. The case is 55mm in diameter and 21mm deep.
A later version of the Ticka has a dummy watch face, with the hands indicating the angle of view. A sterling silver version was also made.
