Hello all. If an automatic watch winds from the crown, can you reduce the power reserve by winding it too often causing the mainspring to slip and having the effect of the mainspring being partially unwound. I have a friend who says that his watch does not run very long after he has wound it. I think he may be winding it too often instead of just wearing it and letting the automatic mechanism function as it should.

Thoughts appreciated, thank you.

Logic says that's not possible because no matter if manual or auto the mainspring is wound anyway. If a long time is passed since the last servicing is a good idea to do it again and throughly check all power and winding components.

when the mainspring slips it only slips a little bit it should still run quite some time.

were missing information? Like exactly which watch is this, how much hand winding does he do in other words how many turns and how long does it run?

it sounds like in real life the watch needs to be serviced.

      In the meantime whilst awaiting a better plan, please drop me a quick hello on my email.

      I looked at it like this, I've built a lot of stuff in my time, building structures and furniture,those are my creations and they will still be here way way after I'm gone. Traditional watchmakers felt the need to pass their knowledge on, ideas that they created . I assume with them as it is with me, leaving their mark on the earth, a way of being remembered. This creation of Mark's has brought thousands of people together to pass their knowledge around,  ideas that will continue to be used for lifetimes. Ideas that should continue to be procured. If for whatever reason the forum ceased to exist, not quite like Ranfft's, that didn't disappear but much less usable. Then that is sad, such a massive loss of communication between good people and a wealth of knowledge lost. There should be something in place for when that happens which could be next week, next year or in 10 years. Might not be a topical subject for a lot of folk or boardering on controversy, i did say i talk about stuff other people dont. But if you dont talk about it and something happens then you've lost it and you ain't gonna fix it .

      I've remained silent on this thread, and at the risk of upsetting everyone, the thing that worries me the most the the apparent absence of Mark. The moderators do a great job and the members also pitch in, and the site seems to run itself, but it is a concern for the future of this forum when the owner is absent for all intents and purposes. Like many of the comments above I would hate to log in one day and things be closed down as I rely on this site for ideas and knowledge and also cheer me up. maybe the Moderators could reach out to him, assuming he does not read this thread, and express our concerns and let us know the plans going forward? some kind of WRT ark

      That was the exact reason for me starting this thread watchie. Still we haven't worked out how the regulars are going to hook up if it goes tits up. I honestly think something should be arranged to stay in contact, we all help each other so much.

      Setting lever spring

      By Neverenoughwatches · Posted

      Yeah ive watched that a few times before,  i couldnt find my old school dividers to scribe it up 😅 Yep thats the guy i bought a roll from . Thanks Nicklesilver that answers that perfectly and more or less what i thought an experiment over time would prove . The jumper arm is quite thick along its length, i left it that way intentionally, i thought the original was probably very thin, i didnt see that it was already missing. Setting isn't particularly stiff as such just positive, i still need to take it out and polish where it mates with the stem release.
