Chalk up one more issue with 3861. Got mine earlier this year. Wear it gently and it just stopped working this week. Off for service
Been there, done that 🙁

My new 3861 that I sent in for Power Reserve issues was returned last week with the original bad part they replaced along with the original hands that they also replaced. Go figure?

Still no word from my AD on the 3861 that I have in for the same issue. Hoping to hear something soon though as it’s a few days past the last ETA from the AD.

Out of interest, what original parts were included with your returned watch? I’m wondering if the bad bushing and worn wheel/pinion were both evident, to better suggest how the fix is being addressed on our watches.

Thanks for the update, and congratulations on getting yours back before Christmas!

I’ll post an update when my watch gets back to me.

Purchased my first Omega watch on Thursday, 3861 hesalite speedy and had to return it today due to the same issue expressed throughout these posts. My chronograph stopped twice at 58 seconds despite the fact it was fully wound. Mini seconds counter on the left dial also stopped. Disappointing to say the least. Mine was ref number 832.

Watches of Switzerland were fine about it although had never heard of the issue, I was showing the sales assistant this forum post. They happily exchanged for the newest one they had received, this one I have is now ref number 833.

I will be monitoring to see if I have the same issues but fingers crossed should be fine. I am wondering if I just got one that had a general malfunction.
Happy to hear that they were so cooperative. Mine is still at service. Btw, where did you find the ref number?

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.

Excellent!
Thank you very much.
Archer that’s interesting, I have a 2017 005 speedie and the hour recorder will not stay reset, there is no solid click on the reset button & although all chrono hands set to 12 the hour keeps moving to about the 3 hour mark then stops, the rest of the watch works fine. If I leave the Chrono running the hour will not run past the 3 position. Have you encountered this before ?

FIFY, this will help to get his attention more easily.

Yes, any times...hour recorder creep...

Just out of interest, what is the first 3 digits of your serial number? The one I had the issues with was 832 whereas this is 833 that I’ve got today.

I’m not sure there is a direct correlation between the serial and date of production; guessing this is something only Omega would know and this is not disclosed.

Hopefully the bushings are sorted on this one. The sales assistant assured me this is the latest one they’ve got in and before I arrived for my appointment ran the chrono for 1 hour.

The first 3 digits of my watch, which developed the issue, are 831….

Mine was 831 also, as another data point. Hoping to get it back from warranty repair soon.

I got my 8361 almost 3 weeks ago. I tried to do some testing today while waiting for my wife inside the car and to my surprise, activating the chronograph will halt the movement of the watch at 58 seconds. Clicking stop/start will kickstart the watch again and will stop. Just pressing stop will kickstart the small seconds hand again. However, I do not know if I'm just having a low reserve. For 2 consecutive days I just wound it maybe 15-20 turns and that's it. I now tried to fully wind the watch and testing the chronograph. It has now crossed the 2 hour mark. I also tested this previously and was able to go beyond 2 hours but I just didn't want to do more test further. Without the chronograph running I was able to get 40+ hours from a full wind (I think 46 hours).

I don't know if the serial plays its part but mine starts with 834.

Edit: I mean if anyone can identify if the 834xxx series were already fixed at the factory.

That sounds word for word, exactly the same issue I had. As this is my first mechanical watch at 23, as a newbie, I am not sure if I fully wound the first watch I had. This morning before work, I had a go at winding it for the first time since Saturday and ensured it was fully wound to the point the crown shows full resistance.

No issues up to yet. If it does it again at 58 seconds I will be sending to Omega like others have.

I read somewhere in this forum about how a low power reserve can greatly affect the mechanism of the chronograph or any other movements with complications such as day or date as it would require more torque to flip the gears (of course not the exact words they used). I'm just thinking that I didn't wind the watch enough and it is stopping at 58 seconds as it prepares to flip the minute counter but didn't have enough strength to do it. They also said that once you stop the chronograph, the actual seconds hand will start moving again as it requires basic movement. That's what's happening to me.

I hope everything is just fine and I'm just paranoid. I have no plans of sending this back to OB for service. I barely use the chronograph functionality anyway and as long as I have good power reserve (like 40+ hours) then I'm good.

If that’s the case it’s most likely a beginner mistake by me 😁 the crown can be pretty tight in my opinion to wind when new. I will be winding it fully each morning.

I will be using the chronograph to time lunch breaks, cooking etc so I’ll be able to test it well the next few weeks.

It's my first mechanical chronograph as well plus it's manual wind so it may add to my curiosity. I have other mechanical watches as well but they are self winding that I can leave in a watch winder if I want them to keep on moving.

People, you HAVE to fully wind a manual watch every day to get proper performance. Sounds like some manual watch newbies aren't fully winding their watches. Wind the crown until it hits a full hard stop and it won't go any further. Field experience shows a fully wound 3861 will go for 60-62 hours with the chrono off. If you are getting much less than that you aren't fully winding the watch.

Thanks for letting us know. It just so happened that i rarely use the watch. I'm lucky if I'll be able to use it in a week. 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. OR, just let it run for like 12-24 hours because it wasn't used for a week. I'm so used with my other mechanical watches wherein I don't know if the power reserve is full because they're self winding.

Btw, i found a debate online on what fully wound really means. Others say that fully wound is when you hit a hard stop. So my thinking is that you should hit a point like you have tightened a screw down crown, it stops. But others say that you'll hit a point where the crown will just bounce back once you reach that max point. The OB SA told me it's the latter and that's what we did.

I am not really sure how one can be unsure as to whether their Speedmaster is fully wound or not. 👎

You are either able to wind the crown clockwise and you hear the clicks as you do this, or you are not able to turn the crown anymore, which means that you fully wound the watch. Everything else is semantics or splitting hair IMO. 😒

Wind it until you can't wind it any longer. Anyone who tells you anything different, really doesn't know what they are taking about.

I don't understand the rationale in that thought process. If you pick up a fully unwound watch in the morning and just want to put in enough energy to make it through the day until you go to bed (say 15 hours) there is just no way to know how much to wind the watch to cover that time span. And a watch with that little energy in the mainspring is not going to give you optimal timekeeping performance during the day, and if you do want to use the chronograph during the day you are likely going to find it incapable of doing so. It's your watch and you can do what you want with it but I don't understand the reluctance to wind the watch fully to get optimal performance. Even if you are only going to wear it for the day it is better to fully wind it when you put it on, you do no damage or suffer any real extra wear by fully winding it and letting it run down after you take it off and put it away.

For me this is like the ongoing debate with the people who recommends watch winder and who doesn't recommend. They all have their reasons why they would throw one into a winder and those who will just say "just let it stop and adjust it again". It's also the same thought process with my other mechanical watches. I don't really care about the performance of my Seikos as I don't really mind its accuracy and ability to keep the reserve. But with my other Omega, I do. However, kickstarting my Omega 8400 by winding it manually, maybe 20 turns doesn't mean that I ain't getting the full potential of the watch because for sure that's not fully wound. I will use it for half a day or so, and still I get 0 to +1 per day and for me that's an absolutely good performance. It will stop less than 40 hours even though it has 60 hour reserve (for sure, 20 turns plus half day of use, i don't expect it to be fully wound). Like I mentioned too, I've had this 3861 for less than 3 weeks so I'm still trying to learn how to use it the best possible way.

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?
