I have done a whole lot of pocket watches and never had to remove the balance to demag, & never had any problems.:)

I would prefer to do it out of the watch and wrapped in paper. probably because ,like you I read it somewhere.

Vinn3 and TimFitz,

Thank you for your recommendations.  I Demagnitized the balance separately and again after the watch was assembled.  It did not make a difference in function.

      Once again I am asking for help.  I cleaned an Illinois pocket watch.  It was running well, but had a lot of lint and other debris inside.  I cleaned the balance wheel and hair spring without taking the hair spring off.  Cleaning was done in lighter fluid in an ultrasound machine.  The movement was cleaned in an ultrasound machine using watch cleaning fluid followed by two rinse soakes.  Everything went back together well.  When the balance cock and hair spring were placed the spring was not parallel to the plate.  None of my manipulation could make it so.  If the balance wheel is manually the escape wheel moves normally, but the watch will not run.  When not in the watch the hair spring is parallel to the balance wheel.  
      I have included pictures.  The one from the side was meant to show the h.s, but is hard to see. 
      Thanks in advance for your help.

      The oscillator, or something, in my automatic wrist watch seems to be greatly affected by outside temperature (summer vs winter).
      It seems to run fast in the summer, and even faster in winter (The manufacturer said they could adjust it).
      Q:  Is this difference with temperature normal/possible?
      and
      Q:  What would cause this?  [a poor choice of hair spring material (stiffer in cold = higher rate)??? a poor choice in lubricant???]
      Thoughts?
      As an Engineer, I like to understand causes and effects.
      As far as my watch is concerned, I will be surprised if there is a year round fix.

      I'm relatively new to mechanical watches and have quickly become fascinated but have an elementary level question that hopefully someone can answer.
      If the hairspring and balance wheel come to a complete stop due to the main spring running out of power, what is it about winding that sets the balance wheel back into motion?  I understand the way the escapement works once it is in motion to input a small amount of energy into the balance wheel, but don't understand how winding alone sets it back into motion.  I know with grandfather clocks you have to restart the pendulum manually and I'm wondering why this isn't the case for watches also. TIA.

      I bent the hair spring attempting to turn the hair spring collet to line up the roller jewel with the pallet fork. Manipulated it and this was the end result. I had to pat myself on the back.

      As per the title, I was checking why my Gigandet Valjoux 7733- based chrono was not working today, and noticed that the hair spring got loose from the small insert that connects it to the balance cock (what's its name again?) Taking a closer look, it appeared to have been fixed with schellac, but I am not sure. Would this be normal, if so?
       
      So now I need to find a way to reinstall the hair spring inside the stud. Heating it gently could be the way, but I am afraid I will only riun the hair spring if not careful enough...

    • I am reading your comment "When i try to wind it, the clutch wheel on the main spring barrel turns but so does the main spring barrel which doesn’t allow the spring to wind." Do all other wheels turn? If so - pallet fork is your main suspect. If they do not, hen tale of the mainspring, remove the lid and check if mainspring is hooked to the arbour.
    • Hi this watch is Rolex gm master11 A good clone needs a tweak thanks
    • In all of my tear down I do not remember removing the pallet fork or even seeing it.  I google'd it to find an image and definitely didn't remove it but that doesn't mean it wasn't dislodged or broken when the watch unwound and the hand slammed the index. It seems like whatever is supposed to "clamp" either the main spring barrel from spinning when in winding position or clamp or disengage the winding rotor when in hack position isn't working properly.  Does the pallet fork play a part in these mechanisms?
    • Then check if pallet fork is installed correctly and that both jewels are present. If that does not help - take the entire movement apart - clean it and visually inspect all pivots, teeth on each wheel.
    • If memory serves me right , I read here on WRT that Rolex doesn't put out datasheet, if available watchweasol gets us link to datasheets in no time,  so I got lazy. Should you decide to repair it, Caliber Number is needed. You have  evrything to gain by taking pictures at every step of disassembly. I don't know if there is a walkthrough ( search function) for you to browse through. Never worked on a Rolex personally, no shortage of knowledge and experience here. I guess its a chrono grade, high precision gears and excellent escapement. The more questions you ask ,the better chance you provide for us to learn. Regs  Joe
