I have the same problem and just bought mine less than a month ago in 2025 so obviously Omega has not addressed the issue with new watches coming off production. Pretty crazy. I chuckle how eveyone says “Omega knows about the issue and fixed it back in 2022”. I know mine isn’t old stock because Omega sells a LOT of this model.
There are a fair number of newbies who have problems with their manual wound Speedmasters, but the issue is often resolved when they learn they have to fully wind the watch for it to operate to spec. You don't stop winding when you feel the first resistance or when the crown rebounds or after a certain number of turns or some other criteria. Simple question, are you fully winding the watch?

You are assuming that the reason yours failed is the same reason...there are other reasons why Omegas fail. If you get any parts back with the watch (which doesn't always happen with a warranty repair) post photos so we can see what they replaced.
True but I haven’t heard of many causes of this particular symptom outside of either the bushing or a friction spring lacking the proper tension. I will report back but I’m not sure when I’ll send the watch in. Since I just got it I’m inclined to wait until the issue becomes more of a problem. I haven’t been able to replicate the chrono hand stopping outside of the first instance. What I do see rather frequently is a stuttering of the hand between the 0-10 second mark after which time it settles down into a steady normal beat.

Thanks for checking, but yes I keep the watch wound and am familiar with the issues that can occur with a watch low on power reserve. I try to read the forums first before asking a question. ;-)

The stuttering is just an improper adjustment of the friction spring, most likely. That is the same as countless other chronograph and non-chronograph movements out there, so 100% not specific to the 3861.

The single instance of the watch stopping can be for other reasons - debris in the teeth, tooth to tooth contact if it stops immediately, improper depth adjustment, etc. The issue with the bushings presents differently - again I doubt that it has anything to do with that.
