That's exactly what I did when I first got it back from SGUS Omega. I wound it 60+ times until it stopped and now I wind it 17+/- times, until it begins winding back, every morning before I put it on. It's running every morning and keeping perfect time. So far so good, yes?

This isn't complicated, even though people try to make it so. You wind it the same on day 2, 5, 50, 500, as you do on day 1. Wind it until you can't wind it any longer is the only answer to this question...period.

Thank you Archer, canˋt be said more clear.

So my thought process is to just wind it just enough to survive the day as I don't want to keep the mechanism running and not actually use it.
what is your goal, are you trying to stretch the service interval so you can pocket the money if you would only have 2 services where others whom wind the watch daily 3 services in the same timespan?

Half winding a watch seems odd to me. Full wind, let power down, repeat the next time you pick it up.

I've only had mine for about a month now, so I'm also still new to them, but figured out quickly the best / easiest way to wind these is simply hold the case in your left hand and just run the side of your right index finger along the back side of the crown. Don't pinch the crown with your thumb / index like every other watch.

It's not actually to avoid the early service but rather get the balance. It's just merely finding the right balance between usage and service.

To me it's the same as my other self winding watches. If it's stopped and it's time for me to wear it, I shake them a bit to kickstart the movement or rotate the crown. But that doesn't necessarily mean that it's fully wound and it will never will even if I am wearing it (i think).

And I would think that any other watch users here (if not some) are doing that same especially those who are using their watches daily. Arrives home, put down watch, wake up the following day, optional shake, wear.

It's just me who decided to half wind the watch because I couldn't care less if the watch is still moving 2 days after when I know the next time I will use it is like in 7 days.

Sure, I understand the mindset. I also don’t let my cars’ engines running day and night.
But to put it in perspective for you: these watches are built to be worn 24/7 for DECADES. So, if you already do not wear it everyday, there is absolutely no harm in fully winding it when you pick it up, even if you only technically “use” a fraction of the power you have put in the mainspring as this represents a minute fraction of what the watch can withstand in its lifetime (even excluding services).

Also, your example on winding an automatic watch with the 20 turns is not comparable to the situation with a manually-wound watch…. Because once the movement has started thanks to your 20 or so turns, then the movement of your wrist will keep winding it automatically.
Anyhow, to each their own, and I 200% subscribe to Archer’s posts and stance.

My watch stopped for the first time last Tuesday when I activated the chrono. I couldn’t get it to do it again once I noticed it was stopped and pressed the button again to start it running.. Brought it home and just did some tests. Fully wound with chrono running it ran 45 hours. I fully wound and let it go without chrono and it ran 64 hours.

I guess I will need to watch and see if it stops again

On any of the three cards - warranty card, pictogram or master chronometer test. Watch number. The orange sticker on the case back also had it on if I remember.
Thanks. 829xxx here.

Yeah, I can't understand why people overcomplicate this so much. Don't count turns etc. Wind the damn thing until it stops.

Then again, I shouldn't be surprised. Omega states that a 50m WR Speedmaster is ok to swim with but forums and Facebook groups are full of people who are still scared to wash their hands with it on.

My (replacement) 3861 has now developed the fault too. Stopped straight after starting the chronograph, and did it a couple of times in a row. Damn.

Time to send it back I guess, might wait until after the holiday season though as I guess the service center probably closes down at some stage.

Hello everyone
I am French
My name is Bruno, I am 45 years old.
I have bought last Saturday an OMEGA Speedmaster 2021 with caliber 3861.
This morning I noticed the same problem with the chrono being blocked.
I discovered this forum while looking for information on the net.
I have written to OMEGA to find out what to do.
Hope to get some good help from them.

sorry if my english is not good because i use an automatic translator
Regards
Bruno

What are the first three numbers in the reference number on your watch? I just received a brand new replacement for the watch I sent back with a totally different defect (highlighting Omega’s poor quality control as of late), and my new reference number starts with 835. Wondering if it is one of the newer batches with the fix. Sounds like even the latest purchases are having this issue, so I am not very confident.

my Speed number 829 bought on november 20 was perfectly new with the protective adhesives still present. The seller told me to have received it 3 days before.
I imagine that it should also depend on the importer and the sales volume by country and continent.

It's called serial number.

Got my watch back from the SC. Been a week and it’s running fine. I will continue monitoring the issue since it only started to show up 6 months after purchase. So far, I’m happy though.
