Does an automatic watch have to be stopped in order to demagnetize?

However, if all you need to do is remove the battery, why not do that. As well, I don’t think magnetism is that much of an issue with an automatic watch, given that it runs on a small servo motor or a stepper motor.

Am I missing something? I've never heard of the term "automatic" used in association with any watch that takes a battery...

And to answer OPs question, I have ran my watches through the demagnetiser running without any apparent ill effect. But you might want to if you can to stay on the safe side

Back to the original question, does an automatic watch need to be stopped in order to demagnetize it. Well, first of all, I do apologize for my brain fart. Somehow my brain mapped the word automatic with electronic and Quartz. Not sure why???

Back to the question. When I demagnetize a watch movement, I always make sure the power is removed as I do not want the magnetic force to somehow scramble the hairspring. Not sure if it would but I do know that when the balance turns to its maximum range and the hairspring has fully expanded, it is at its least tight point and perhaps could be vibrated by magnetism. So I would let the power down on the movement, then demagnetize.

Thoughts?

   as far as i know;   automatic means "auto wind".  AND recently learned : only that mainspring has a clutch  so the winder will not break the main spring.  a good reason to stay with quartz  watches.  vin

I presumed JD was thinking or talking auto quartz movements. 

The expression in question applies to me personally, I am glad it dose, since it evidences, I must have a " brain" somewhere. :woohoo-jumping-smiley-emoticon:.

      About repair watch's jewel.

      By jhoho202 · Posted

      First of all, thank you for the pdf file of the book on how to replace a gem. So, if there is a problem with the ruby in the movement, should I buy a new or used movement and replace it? When I watch videos on YouTube of people fixing used watches, I feel like there should be a way to buy a gem. Is there no way to buy it?

      Parts sourcing for FHF 180 movement

      By praezis · Posted

      I suppose @donutdan is not forced to earn his living by repairing watches.  I suppose he does it as a hobby and wants to gain experience, to get better in watchmaking and time is not the issue. Then @donutdan should rather try to repair the damage instead of swap parts from a maybe intact other movement. Swapping parts is not watchmaking. And often swapped parts are not the expected solution of all problems. All mentioned damages are repairable. Frank

      Yeah I figured that one out when I googled and realized that my spindle is actually from Horia. It's smooth with no screwable cap.

      Parts sourcing for FHF 180 movement

      By JohnR725 · Posted

      I am puzzled by something a snipped out something from your image and what exactly disassemble tell us? my confusion is the symbol for FHF looks like image I have below year symbol as a star and righted this instant are not finding what that means? I suppose we could use the fingerprint system to verify it really is what it claimed to be. Size itself is really interesting there's almost no watches in that particular size. Then were missing details in the photograph above like diameter of movements to verify it really is the size and are missing the setting components.   went to the bestfit book looking at the symbols didn't see it. Look at the link below I did find it back to the bestfit book and yes it really is there https://reference.grail-watch.com/documents/history-of-ebauches-sa/ then bestfit book says lists the size as 10 1/2. one of the problems with vintage watches is finding parts yes a donor watch would be good.

      Oiling Dubois Depraz chrono module pivots (Omega Speedmaster Reduced)

      By Simeon · Posted

      Actually, this could be the issue. Drag from the module could be overcoming the cannon pinion. It was definitely not at the point that the driving wheel was loose on the cannon pinion, it took a little bit of effort to rotate it when applying the grease. Maybe I need to look again at applying oil to the pivots.    Yeah, it's very annoying. I don't want to give up on it, so back on with it over again until I catch a break.
