Hello guys,

I'm servicing a ATTA with JEAMBRUN 23D movement.

Does anyone by accident know the liftangle for this type of movement?

I can't find any info on the net. It seems ist amplitude gets to high but i want to know the correct liftangle so i can discount that as a problem.

Thx in advance!

It always helps to give us a picture Or give us a link to a picture so we know what you're talking about. For instance the link below we can see what it is.

Typically for wristwatches the lift angle that it defaults to will be just fine. If you're obsessed and you actually have to know what the lift angle is you can follow the method outlined in the video below

      [Myota2034] Custom simple quartz watch — PricewaterhouseCoopers On a very very different note, here is a watch from approximately 2000 when I was a Partner with PwC, Management Consulting. It was a simple “marketing watch” with a clever “vase of knowledge” that is subtly revealed on the dial as the second hand progresses. Clever for a simple watch!⌚️

      Mainspring winder question.

      I think someone else has though. Some where here using a modified perspex sheet. I may be wrong i may be right , i think it involved fitting the arbor to a pin vice. I dont have experience of the bergeon winders, are the handles not interchangeable ?

      Dial Dots

      By Neverenoughwatches · Posted

      Never tried dial dots, i always considered them as a bit of a bodge.  You are adding something that was never intended to be there. I wonder how the adhesive reacts to any part of the movement, hot summer heat and i think things might turn sticky. Most adhesive backed stuff has a tendency to soften and slide around so it may spread, i have used a lot of so called sticks all adhesives in my industry that are just not up to the job. I suppose they get you out of a problem quickly, but how permanently might that be ? I would just explain to the owner that it may or may not work. WWs other ideas are a much more permanent solution but both have their risks . I've tried milling and dial feet replacements, hmm it was ok, ive heard of folk dimpling the face , so that needs care . And i have soldered a few times , all with good results but i am very careful and I practiced it a lot.
