    Hello!

    I'm looking after information about this Bulova. I have no informations, sold as an aircraft clock but I don't think it is correct.
    There is a "coil" who start the elapsed timer, stop it and reset it.

    Sold as NOS but because of packaging the second hand is broken...

    Looks like a mechanical watch with a mainspring barrel and a balance wheel. Large knob on the front would wind & set and another on the opposing corner for the elapsed time. The big coil may be for a light or backlight?/

    Hi!

    Thank you for your anwser.
    Yes it is a "classical" mecanical movement, with 2 mainspring, wind with the knob. When I move the metal plate under the coil like i think it will move with electric contact on the coil (act as a magnet), it start/stop/reset the elapsed timer. You can see a small spring and the mecanism of this system in the last photo.

    Could quite easily have been used as an aircraft or even a car clock. Would be better to have seen it in original casing.

    Here a video of the mecanism, if it can help to identify the clock!




    Thank you!

    It is a very cute rotary solenoid. I would have thought that Bulova made it. It is the sort of thing that might have been used in road rally's or possibly in aviation. Clearly it was intended to be in a dashboard of some kind.

    I have an answer from Bulova. No more informations about the use, but seems an interesting clock!

    "
    This 8 days clock was a special project from our timing lab, they did special clock for places like the national weather service and Nasa during the 1960 and 1970’s
