The aircraft on-board clock The aircraft on-board clock is used for control and navigation. It is a movement with a diameter of 80 mm, a square front plate and a running time of 8 days. A lever offset to the left starts a flight time chronometer, stops it again and returns it to its zero position. The flight time is indicated by an hour and a minute hand that are attached eccentrically to the left. The mechanism of this flight time meter has been simplified considerably. The design was used for the registration and protection of the design. In addition, this watch basically has a stop device for measuring short times (chronograph) for blind landings. This short time is indicated by a central second hand and a minute hand offset eccentrically to the right. The stop device is triggered by pressing the right button. In addition, this right button is used to wind up the watch. The hands can be set using the middle button of the watch. Based on the experience gained with instruments of earlier designs, this button was not connected to the winding button. In the past, this meant that the button that was pulled out to set the hands remained in this position, thus locking the movement. With this new model, the button must be pressed in and turned to set the hands. The button then pops out again and problems with the movement are no longer possible. The dial and the hands are coated with luminous material. The movement is relatively well protected against moisture. At temperatures below -20°C, a built-in heater guarantees that the watch will function. The movement has 22 jewels and is equipped with an anti-magnetic, self-compensating hairspring.In the first half of the 1950s, the VEB Glashütter Uhrenbetriebe received a government contract for the GDR aircraft industry, which was then just starting to develop a clock for the first passenger jet aircraft , type 152. This development was completed in 1957 with the GUB movement caliber 71. The clock presented here with the movement number 115 is the earliest clock documented to date. This high-quality 22-jewel, heated 8-day movement was manufactured in small numbers by the GUB until 1967 for the civilian market of the CMEA states .
