The Worst Timegrapher Reading?

A de-magnetiser is an essential tool in your workshop. You should de-magnetise every watch after service and before regulating.


But I am not entirely sure magnetisation is the fault here. Check that the coils of the hairspring are not touching each other. 


To illustrate this I have made a quick video which shows readings for both faults and you will see what I mean.


I will upload it today and update you when it's available.

Thanks. Looking forward to view the video.


Regardless of the issue to this watch I received, I've been wanting to get demagnetizer, so could you recommend one or two demagnetizers?

The Etic 340.400 is a good demagnetiser and this is quite cheap. You can get cheap Chinese clones of this tester which I have and it works fine.



I also have an Elma Anti-Mag and this is an excellent tool but quite a bit more expensive.



I have done a demonstration in the video I am uploading so you can see how they both work.

I have purchased a demagnetiser and it doesn't fix the issue.

Now, I am still trying to find the fault on the watch. Thankfully the watch owner is patience and let me have as much as time required to fix it :)

Well that's disappointing.


You are best to focus around the escapement.


Check the hairspring carefully. are the coils touching at all? - it is in the index?

take the balance out - is the spring flat?

check the balance roller - is the ruby pin loose? is the roller loose on the balance staff?

Check the pallets - is the guard pin loose? Are the pallets secure on the pallet arbor?

Check the balance jewels - end shake and side shake.

Has the balance got timing screws on the rim? Are these touching?

Is the balance wheel true? Is the balance wheel touching the pallet cock in certain positions?


On the timing machine do you get this reading both dial up and dial down? and how about pendant down?, pendant up?


Check the hairspring point of attachment to the hairspring collet - is it loose? What about the hairspring stud screw - is it tight?


I hope I didn't miss anything out :)

      I measured my Omega Caliber 1120 through an timegrapher app. (Dial Up, full wind)
      I know the app is not very accurate.

      I checked about +100s/d difference and sharply tilted graph .
      The odd thing is that the bottom part of the graph is not printed every 100+- seconds.(red-colored circle)
      Is this a feature of the timegrapher, or does it indicate abnormal state of movement component?
      Thank you for the comments.

      I am new to watch repair and have mainly been servicing simple eta movements for my own
      I have always wanted a chronograph watch and have found a watch based on a valjoux 7750 with a broken case.
      I want to put the movement into a new case but the dial is a day date and the movement is date only.
      I have sourced all the parts and have fitted them to the movement to add the day function.
      The donor watch didn't use a dial washer / foil, do I need to use one now I have added the day indicator?
      If I do need a foil, what size and where from?
      Thanks very much

      Hi, my name is Ross. I am a rookie watch enthusiast and I am really puzzled here.
      Could someone explain to me what kind of a problem am I facing with my timegrapher?
      I do two sets of measurements with the same watch (1 day or 6 days apart) and receive vastly different results - to the point of being completely different from what I observe in real life. 
      For example, my timegrapher shows that my watch is running fast (or ahead of time), while in real life I observe that it runs 7 seconds per day behind. I even recorded a video about it so you could see it for yourself: https://youtu.be/mhGzf6aLMlY
      How should I interpret that? Am I doing anything wrong?

    • How do you finish off the parts you don't clean with isopropyl at the end? Do you just let them dry after their first rinse? Edit: oh wow, just realized I commented on a 5 year old post. Not sure if I can delete.
    • Did u happen to find large basket for it? I have small and it dsnt do it well. Looking for a larger basket for the same machine
    • Any good ones for lnr master? I just got a used lnr master and need a bigger size basket the small one just doesnt do
    • Sewing thread, orphaned earrings, long dead mice; you never know what you might find in a used clock.
    • Maybe the mods could move the post? Probably better than a duplicate post. I'm sure one will chime in when they come across the post. I'm very new as well, that was one suggestion I saw in a video that was helpful, and much more gentle on the parts. Another thing I've heard which I think applies in this regard is if something feels "off" or like it needs to be forced at all, something is probably wrong, not seated properly, etc and you should stop screwing and go back a step. With the level of precision movements are manufactured to, it should feel just right. When you were assembling the train wheels did you do so in the order indicated on page 3 of the manual? Reverse order steps 49-35 - if you get the ratchet wheel screw on you should be able to give it a wind by turning the screw to the right.
