Junghans Pocket Watch Reference.


Recommended Posts

Hi,

 

If you fancy some Junghans pocket watch information have a look at my website:

 

http://dirkfassbender.de/movements-1.html

 

On the other hand I would be grateful if you have some informations which are maybe missing.

 

Junghans is not so well represented on the internet which I would like to change.

 

Best regards

Dirk

Any hints are most welcome.

Hi,

I have constantly updated my information about Junghans pocket watches last year and lately I have started to search for serial numbers to maybe shed some light onto this subject.

First results here: http://dirkfassbender.de/serial-numbers.html

Any help is welcome. I look for low and high movement numbers and especially dedication engravings which could give hints for better dating Junghans pocket watches.

Best regards

Dirk

Hi... I'm trying to get some info on my pocket watch but can't find anything relevant to it. Its a Junghan, inside the serial numbers that I can see are 15646/J29 a.... it's got a Swastika on it, I can't find a single watch like this so any help would be appreciated. Thanks.. Michele

    • I'm assuming that every time you set the watch you are work hardening the detent spring, maximum hardening is  where it meets the plate due to maximum deflection.   That's why it snaps there.  The Young's modulus may be the same but after it's reached its maximum yeid strength it breaks.  My mechanic engineering is very rusty, correct me if I'm wrong. 
    • Ah ok yes that makes sense to polish it where the arm starts to form from the body of the bridge, i thought you meant the underneath of all the arm.
    • this is something I've never quite understood about the some of the Swiss companies. In 1957 Omega was using 9010 for the keyless parts with epilam. there's been a slow migration towards using heavier lubrication's but still typically oils and epilam to keep them in place. When it seems like 9504 works so much better.  
    • OK, welcome in the world of alarm clocks... I guess the 4th wheel is dished because it is from another movement. If it was not dishet, then it would not mesh with the pinion of the escape wheel, am I right? The marks of wear on the 4th wheel pinion doesn't corespond to the 3th wheel table position, at list this is what i see on the picts. Calculating the rate is easy - there is a formula - BR = T2 x T3 x T4 x T5 x 2 /(P3 x P4 x P5) where T2 - T5 are the counts of the teeth of the wheels tables, and P3 - P5 are the counts of the pinion leaves. Vibrating the balance is easy - grasp for the hairspring where it should stay in the regulator with tweasers, let the balance hang on the hairspring while the downside staff tip rests on glass surface. Then make the balance oscillate and use timer to measure the time for let say 50 oscillations, or count the oscillations for let say 30 seconds. You must do the free oscillations test to check the balance staff tips and the cone cup bearings for wear. This kind of staffs wear and need resharpening to restore the normal function of the balance.
    • Glue a nut to the barrel lid, insert a bolt, pull, disolve the glue.  Maybe someone will have a better answer.
