History of spy-cam watches
The Watchismo blog has a mind-blowing history of early spy-cameras built into wrist-watches:Link1960 Tessina Cameras featured the only subminiature watch that uses standard 35mm film but is the size of 16mm cameras. A rare version exisits for the wrist (above) and one with a Swiss watch attachment (below). Made up of 400 parts and built by Concava of Switzerland, the Tessina was also designed and patented by Dr. Rudolph Steineck.
