Can Anyone Help Me With These Readouts

So i have put my balance in beat to get a better reading however however i've got the most ridiculous readings now.

 

I mentioned before that this watch was giving very different readings between the dial up and side.

 

it seems the tracks have doubled.

 

The balance still looks perfect, is straight and is "breathing" well when spinning 

 

anyone can chime in that would be great.  im thinking maybe its something else and not the balance anymore.

 

Thanks for looking.

Just thinking out aloud here.

 

You said in your previous post thread that you adjusted the banking pins inwards as they looked like they had been moved apart.

Could this now be affecting the locking and unlocking of the escapement to cause knocking on the pallet jewels?

 

If the impulse jewel is now sitting central of the pallet fork at rest then moving the banking pins back out may give the lever a bit more swing to clear the knocking on the pallet jewels. As long as it doesn't go into overbanking.

I suggest you get it back to basics. Put the banking pins back straight, checked the impulse jewel is not damaged or loose, double check the hairspring is not fouling anywhere , check the pallet jewels are not loose  or damaged. Also check that the impulse jewel is in the correct position when the balance is resting (it should be spot on in the middle of the banking pins) if it is not then the hairspring stud needs turning on the balance staff to achieve this. Mark has a Vid on this procedure.

Finally when all is correct give it an ultrasonic clean re-assemble lubricate.

Was browsing Youtube recently and came across several videos by    perplxr.  Just enter this in search and they come up.  There is one which covers banking and overbanking very well.  The close-up movies are brilliant.  Also covers lubrication and other aspects.  Well worth a look.

      Main spring

      By Jon · Posted

      I would go for the dearer spring. You won't need to remove the spring from the carrier ring and then use a mainspring winder to get it into the barrel, for a start. Also that spring is closer to the needed dimensions, especially the length. The length plays a part in the mainsprings strength. If you double the length you will half the force (strength) of the spring and vice-versa. A spring with 20 mm less length would be about 7% shorter, so technically would be 7% more strength, but I find halving this number is closer to real-world findings, so the spring would be about 3 to 4% more strength/force. On a mainspring that ideally kicks out 300 degrees of amplitude, a 3% increase in amplitude would be 309 degrees. Increasing or decreasing the length of the mainspring will affect the power reserve to a greater or lesser degree. It depends how much shorter or longer it is.

      What tools does ebay have to offer this week.

      I recently bought this but not on ebay. I figured if I want something Japanese I better check Japanese auction sites since these don't seem to pop up on ebay. I paid 83 € plus shipping & taxes. I think it was pretty reasonable for a complete set in good condition.

      Did you take the friction pinion off the large driving wheel and grease it? Although, now that I think about it, that shouldn't have any effect on the free running of the train if the friction pinion isn't interacting withe minute wheel/setting wheel...

      I did in fact use Rodico to get the spring into general position and "hold" it there while I used a fine oiler to make subtle positional adjustments.

      The two measurements of particular importance wound be the height and the strength,  the length would obviously correspond with the increase/reduction of half mm of barrel diameter. There is a big difference in price considering that the more expensive one is the shortest. The longer one might be ok ? But then it is taking up more room in the barrel, might it effect the unwinding ? I wouldn't have thought so for just that small amount.  Ideally a pro might reduce the longer one to suit. But there is some information that might help, do you have the one that was fitted to measure up, though not necessarily the right one.
