I’m a fan and collector of Junghans chronometer watches, but also enjoy some of their more unusual watches with funky designs. This is the second-generation quartz movement from Junghans from some time in the mid 70’s.
The watch is in decent condition considering the age, but is not running!
The movement is pretty funky, with acrylic plates, 9Jewels and a hand soldered circuit board. After some testing it reveals the coil is damaged.The movement is out of the case and the hands are of the dial.Plastic fantastic. The covering plate, date ring, date wheel, hour jumper and hour wheel all made out of plastic.There is not much visible dirt, but there are lumps here and there that will cause havoc to the movement.This watch is very different to other watches I have done! So it takes a little longer than a normal watch to take apart.Here I have removed the train bridge and you can see the gear train. Note the see though plastic plate and the friction spring leaning on to the center seconds pinion.I have removed the circuit board, coil and most of the gear train.To get to the center wheel and base plate I remove the plastic plate.After being cleaned the base plate is looking much better!I oil the center wheel and put it back in place.Setting mechanism back in the place.I put the gear train back in place.Date mechanism working again. Easy to see if everything is working as it should thanks to the see-through plastic. Pretty nifty quick-set function on this watch.Now that’s a quartz crystal!The king of Junghans,Torsten, was very kind and donated a working coil for my project and I now have a working watch again!The case back has a spring to hold the battery in place and you can still see the factory markings.That’s a funky quartz watch!Actually it is funky enough for me to wear! It is the first time I’m wearing a quartz watch in 9 years;)
