The replacement had the issue, too? That's totally not acceptable in my book. Omega claims they know the cause of the issue. This means that either this watch was sent out irresponsibly without the necessary update, or they don't have the cause fully determined.

If the replacement was sent by Omega, I agree. But if it was just the AD giving a replacement from on hand stock rather than forcing @tooch to wait for a repair, then I think it's not very surprising that the replacement was not yet one of the examples with the updated bushings already installed.

Yes, that seems to be what happened. Went back to find his previous post because that sounded concerning, but he said he encountered the issue on his original watch after only one week and had it replaced.

Yep, it was replaced with a new watch from the AD. This happened months ago though so it’s highly unlikely that there were any ‘revised bushing’ models in circulation at the AD’s yet. I was kind of expecting this would happen again at some point.

@Archer,

Al,

When Omega or any other manufacturer issues a service bulletin or similar notification of required movement changes/upgrades, do they ever issue a known failure rate?

Only by reading anecdotal accounts regarding the 3861 here and on the Omega Forum, it seems like the movement just predictably presents the problem on a regular basis. 10%? More?

I don’t own the movement; I’m just curious.

Good question. Generally speaking when these service announcements happen, they are in the middle of whatever problem is presenting itself, so at that point I don't think Omega even has solid numbers. So in this one for example, this was what was written in the announcement:

"Intermittent stops, unstable rate or low power reserve have been observed on some watches equipped with the caliber 3861."

So this is pretty typical wording, that "some" watches experience it. Back when the DLC barrel issue happened, they said it only affected a "small number" of watches, but they still revised the part and issued the bulletin. On that one, the parts were only to be changed if they displayed the problem, where the 3861 the exchange of the two bushings to the new parts is mandatory.

I've never seen one with any numbers just general statements like these. Note that these are documents for service providers, so the key information is what to do, rather than how often the problem occurs.

Perhaps “mandatory” = a perceived threshold since as you point out, the actual rate would depend upon accurate consumer feedback (?).

Thank you!

Hello everyone

My name is Bruno, I am 45 years old.
I have bought last Saturday an OMEGA Speedmaster 2021 with caliber 3861.

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.

Yes, there is a well known issue
it requires some attention by Omega watchmaker to swap out some parts
I hope Omega/your dealer serve you well
all the best

Finally got my 3861 back today in a sweet new case along with the parts replaced. I’m assuming those two tiny rings in the top of the bag are the bushings? So nice to finally have it back! From the day I shipped it back to the AD to the day it arrived back at my house was 9 weeks and 2 days.

I have been randomly starting the chrono and letting it run for about 10-15 seconds to see if it locks up. Mine would randomly lock up within seconds of starting the chrono before I had it repaired. If it got past that initial startup, it never had any issue. So far no issues since getting it back.
