The movement rebuild has been completed.
The pictures show the movement and cover then the complete movement with the cover fitted.
Working from bottom to top...... the space lowermost takes a 'C' sized cell. Above is the solenoid and current limiting resistor. Next is the weighted lever which is flipped clockwise when the solenoid operates. The electrical contacts can just be seen below the centre of the lever; one on the lever, the other on the armature of the solenoid. The lever does nothing as it is equally balanced at the ends. The mainspring underneath the lever is what provides the power to operate the movement. The adjuster for this spring is the (slightly damaged) brass fitting in the centre of the lever. Looks like some useless excuse for a clock repairer used pliars instead of the correct tool. I'm surprised how many so-called 'professionals' cannot execute the simplest of tasks because they don't have the correct tools. The hairspring and balance wheel are above the lever and now run smoothly. no lubrication needed because these are jeweled bearings. Finally, the pointed lever at the top is for time adjustment.
All in all, a nicely made movement, albeit hard to service and repair when compared to similar types. Once it has been adjusted and is running, it will be fitted to the clock body.
The Junghans movement is not particularly common as it was well made and therefore expensive. Why use metal gears when UK manufacturers like Smiths could get away with making movements using plastic ones? Why use brass front and backplates when a piece of stamped aluminum sheet does the same job? Why did the British clock manufacturing industry ultimaltely fail? When comparing these quality German movements to the British crap at that time, it was similar to compared a Mercedes 180 to an Austin Allegro.
