Swiss - Mechanical - used for timing the length of telephone calls – excellent condition You are looking at a very rare piece from the watchmaker Georges Favre-Jacot & Cie, Le Locle, Switzerland. This time piece is a rather special one, used for timing the length of telephone calls. As this is a timer and not a clock, the main dial/hand counts minutes instead of hours. The small counter has an interesting scale (12, 24, 36 & 48) indicating seconds up to 48 sec. By moving the lower lever from left to right, you start the counter. As soon as the conversation is over, the counter is stopped and then reset to zero by pushing the control from right to the left. The timer has a red bakelite base plate with metal backplate with ornamental grind, and engraved serial number. Markings on the dial: PAT 12336/08 S.G.D.G. 373533 / D.R.P. 189161 35608 ZENITH Fabriques des Montres Zénith Le Locle Suisse Dial diameter: ca. 50 mm Condition: Works Perfect The dial is in excellent condition
