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;)
I have Find one i think its more than 50 years old..
Bonjour.
J en ai une qui fonctionne parfaitement et je voudrais bien la vendre.
Pourriez-vous me faire une estimation.
Merci
Mes salutations.
Hi guys i have one of these and was wondering if i sent it to you could you get it up and running? When i put a battery in it, it barely moves the gears inside it,
Mark,
I am afraid we don’t do quartz watches any more.
Best regards,
Christian
What is the value or a working model like this in decent condition?
Look at completed auctions on ebay. We don’t provide valuations I am afraid.
hi!i just opened the same quartz watch -found the coil damaged.Can you still buy those?
I am afraid not…
The ceramic variable capacitor on those older quartz watches was used to ‘pull’ the crystal to minutely change the resonant frequency. Is performing that ‘regulation’ part of a service and what equipment do you use?
Thank you so much for maintaining your blog- fascinating reading!
We have a proper quartz watch tester that has a reading for the accuracy of the movement, and we use that to adjust the movement. If there is a regulator, we will do this as part of a service – but don’t forget that we don’t really do quartz watches 😉
Mitka,
Nice to see another Junghans coming back to life. Your Junghans was produced in 1976 according to the markings on the main plate (K76).
The 667.xx quartz series was produced between 1976-1978.
Thanks Torsten, pretty cool to know the production date!:)
Very nice watch! I’m looking forward to buy a max bill from Junghans as I believe it’s one of the finest examples of bauhaus aesthetic and reasonably priced.
Also it’s interesting to see you working on a quartz watch! – by the way, my omega seamaster 120m ‘plongeur deluxe’ (cal 1337) is still in want of a service 🙂 it’s in working condition, but the seconds hand sometimes get sticky when I set the time, so I believe it’s time for a cleaning… please let me know when/if you’re accepting watches again and can make an exception for quartz 🙂
Plastic fantastic indeed, looks like a cracker toy inside!
A very high grade cracker toy;)
Nice clean face, I guess a 39mm dia size? I wonder how many would actually service a quartz watch. Nice. Secretly every WIS has a quartz watch somewhere!
