I was given two old watches to fix yesterday. An old Everite and a Longines. They have been in a drawer for many  years. I stripped the Everite,  and well serviced it but it does not run well. The Beat error is 600 micro seconds (0.6 mS) and the balance amplitude varies between 140 and 190 deg. The HS is fine. The lever flicks to the banking and the Draw seems to be OK. It is keeping time to about +2 mins/day face up and a smaller amount face down,  The best I can achieve.  It does not look very good on the timegrapher. Is this a case of general Bal/Esc wear. The end stones look OK. Under the microscope I can see pallet jewel  witness on the teeth of the ESC wheel.  It was purchased in the thirties and used for many years. I have boxed it up. Perhaps someone will comment.

Did you check the impulse jewel to see if it was chipped or loose? What type of oil did you use on the ecsapement. You know pallet pivots should not be oiled as it can and will cause drag.

Thank you for your help Oldhippy. Yes, the impulse jewel is firm. I used a tiny amount of 9010 oil on the escapement but not on the impulse jewel. I did however use a touch on the pallet pivots !!!! I will remove this today.  I do not feel safe without the tiniest touch of oil on most bearing services, a habit that I must get out of in some areas.  I can see where you are coming from with regard to the pallet pivots not being oiled, oil could be the cause of a weaker impulse to the balance,  I will let you know how I get on in due course. Many thanks for your constructive and expert help to an old Jobber !!. Best regards, Mike.

Hi oldhippy, I have just finished the Everite watch and your comments about oiling the pallet pivots were Spot On!. I cleaned them with Acetone, dried and then re-assembled the balance. The balance now has a steady 220 deg. Amplitude.  I have timed it to +30 Secs per day. It is much better now. Thank you so much for your correct diagnosis and perhaps 9010 is a little stickier than I thought. I have learnt something from your years of experience and am most grateful to you. Thinking about it there would no real need to oil the pallet bearings as the rotational moment is so small,  I realise this now that  you pointed it out.  Thanking you again,  Best regards, the old Jobber  Mike.

 

 

spot on !.

Thank you again. I could hardly believe the oil on the pallet bearings could have that much effect. I will not oil them again. Mike.

Yes it is hard to believe the retarding effect of oil on pallet pivots. Even worse is: if the watch( some movements, especially pin pallet)  isn,t worn for couple of months, oil can freeze the pivots from functioning.

      AS2063 - hand setting

      By Mercurial · Posted

      Have you got the pallet fork installed in the movement when you see the train move when using the setting works? As nevenbekriev said, without the pallet fork to lock the train, the behaviour you are describing is normal. If this is happening with the pallet fork installed, you have a problem in the gear train, it should be immobile when the pallet fork is locking the escape wheel.  The fit of the circlip above the pinions on that wheel is crooked in your pictures, it should sit flat up against the upper pinion as in Marc’s picture.  Hope that helps, Mark

      Stem broken - can it be rescued?

      By Khan · Posted

      Hi I got a Jaeger LeCoultre K911 movement, where one of the stems was broken. Part no. Should be 401.  Im based in Europe and tried Cousins but its discontinued. They except to get stem in stock for cal. K916 but will that work? Or Is there a way out to join the ends?

      The part was how it fell out of the movement - the train wheel bridge wasn’t screwed in.    I’ll probably dismantle the part, if I can, to work it out.    The train of wheels ran fine - it was only once the keyless works were installed I noticed the problem.

      Balance staff sourcing?

      By mthomas828 · Posted

      Hello, I am about 5 months into watchmaking and I love it!   The attention to precise detail is what really attracts me to it. (and the tools!) I am working on a 16 jewel 43mm pocket watch movement.   There are no markings besides a serial number (122248) .  The balance staff needs replacement. The roller side pivot broke off.  I successfully removed the hairspring using Bergeon 5430's.  I successfully removed the roller using Bergeon 2810.   Did i mention I love the tools?! I removed the staff from the balance wheel using a vintage K&D staff removal tool  with my Bergeon 15285 (that's the one that comes with a micrometer adjustment so it can be used as a jewel press as well as a traditional staking tool...it's sooooo cool...sorry..  can you tell i love the tools?) No more digressing..  I measured the damaged staff in all the relevant areas but I have to estimate on some because one of the pivots is missing. A = Full length  A= 4.80mm  (that's without the one pivot...if you assume that the missing pivot is the same length as the other pivot (I'm sure it's not)  then A = 5.12 mm...(can I assume 5.00mm here?) F=  Hair spring collet seat  F=  .89mm   (safe to assume .90 here? .. I am sure that my measurement's would at least contain  .01 mm error ?) G = balance wheel seat  G = 1.23 mm  (1.20mm?) H  =  roller staff  H =  .59mm  (.60 mm?) B  = bottom of the wheel to roller pivot   B  = 2.97mm  (3.00 mm?)     here I am estimating  again because this pivot is missing. So my friends, and I thank you profusely,  can you point me in the right direction as to how to proceed? Do i buy individual staffs?  or an assortment?   Since I don't know exactly the name of the manufacturer, will that be a fatal hindrance?   Tbh, I'm not even sure what country of origin this movement is. Thank you!

      Epilame / Fixodrop

      By Neverenoughwatches · Posted

      Thats why i asked that question earlier, what happens if lubrication is placed directly on top of epilame ?  As opposed to walled within its non epilamed area . I'm not saying its right, i have no idea , just asking questions.
