Speedmaster Squealing noise at winding end

FedFod

Exactly! Precisely like if you twist a rubber donuts.
It’s kind of encouraging to see I’m not the only one.
Anyway, I didn’t wind the watch yesterday evening, and this morning was still running, which means it ran for about 24 hours.
So probably it’s not a broken mainspring luckily : )
I’ll keep you updated if I find something out

Likewise.

The sound is like an o-ring is being squeezed on rotating the crown. I wonder if it’s a gasket on the crown?

My watch runs fine and keeps decent time. I wind every morning.

The crown does have a gasket, so I suspect this is what you are hearing, especially since they are both new watches. I also suspect you both are on the younger side and have better hearing than a lot of us, and so can better detect the higher tones. I listened to the video with my 50-year-old ears and didn’t notice anything unusual.

I have a Speedmaster 60th that makes the same O-ring rubbing sound near the end of winding. It has done this since it was new. I also have a 145.022 69 that does not make this sound.

I had always assumed it was something to do with the mainspring getting tight. It has never bothered me, but now that this thread exists I'm curious what it is in the 1861 that makes this sound.

I will turn 53 next week I too couldn’t hear the sound on the OP video. I can’t figure out how to post a video to this site, but on my watch it’s quite an obvious sound.

My 1861 was bought new in April 2019. It only started squeaking a couple of months ago, not from day 1. That is why I am concerned.

I have a brand new Moonwatch with the same thing. Just the last few turns it is not the same sound as he 60-ish turns before. No idea how to describe I but I thought this would no be relevant an never paid attention to it before I read this thread. Mine is two months old. Interesting to see how this search for “the sound of 2020” ends....

Just sounds like a watch being wound to me...

And there we go with a better recording.
In the beginning we can hear the normal winding sound, at the end it starts the "squeaking" one.

No problem, I will wait for this evening and make another recording of normal winding sound, and arrive all the way to the end where it will make the "squeaking" sound.
I know this is probably an overreaction, but I'm anyway in quarantine so have a lot of time in my hands : )
I will upload it here, so if you are curious you can check it Archer, thank you in any case
