Minifon wrist watch microphone




Used Google translator

    The microphone is camouflaged for a man's wristwatch. They were produced from 1951 to the middle of the 60s as accessories to portable dictaphone Minifon. During this period, the manufacturers changed two times, at first it was "Monske & Co. GmbH", since 1953 "Protona GmbH", and after the 62nd "Telefunken".
     As these dictaphones at that time were used by special services of many countries, it can be assumed that such watches were also used by spies. Indeed, camouflage is pretty good, and if used correctly, the wire that goes into the sleeve will not be visible. The microphone itself is piezoelectric, with good sensitivity, and is perfectly suitable for practical use. However, unfortunately this is just the camouflage of the microphone, and the clock mechanism in the case is missing, there is simply no room for it. This of course was a weak spot of camouflage, since an attentive person could notice that the hands of the clock do not move.
     In different years, several design variants were produced, featuring inscriptions on the dial and on the back cover, as well as the color of the case, was a variant with gilding. The connectors, of course, could also be different, like the dictaphone with which they were used. Microphones themselves in different years also had some constructive differences. I have two such watches of different years of release, with different inscriptions on the dials, and different microphones. There was also a more sophisticated version of the luxury version with buttons for remote control of the recorder. The microphones in them were very small and rectangular in shape. The design drawing of such watches will be found at the bottom of the page. In my watch the buttons are not real, there is no remote control. Case diameter 39.6 mm, thickness 13.4 mm, weight with strap and cable 55 g.

       The luxury version had buttons for remote control of the recorder. Such watches were used with transistor models Minifon Protona Special, Minifon Attache, and Minifon Hi-Fi, which had a nine-pin input connector that included remote control. Such a clock is now very rare, and unfortunately I could not find them.
      The watches I have without the remote control function are suitable for the Minifon Mi51 and Minifon P55 dictaphone with two-pin input connectors. Buttons in them are not real, and are part of the body.
