Omega 3861 issues?
Just wondering if any owners have noticed any issues with their watch stopping when the chronograph is engaged. Just interested as a potential buyer. Have heard the seconds hand can stop when chronograph actuated. Some think it has to do with low power reserve at the time.

I heard similar stories only after I bought my 3861 Speedy in late August. From what I read it seems that Omega have devised a 'fix' that involves replacing a centre spindle bush with one of different material and that this was being built into new watches from earlier this year. I wrote to Omega via their website, giving my watch serial number, to ask if they could confirm whether or not it had the modification and, if not, would they be issuing a recall to fit the fix. I received an acknowledgement but haven't had a reply to date.
Meanwhile, my watch is working perfectly and I'm very happy with it. Stan. |

I own the 3861 and have not heard this. My watch is functioning flawlessly.

There is a long thread regarding this on omegaforums, with the title "3861 movement broken? *Update: Read First Post*" |

No issues with mine. Bought it when they first came out.

Bought the first production of the 3861 on my 50th Ann piece, no issues to date.

It’s not the chrono causing the issue, but the fact the watch loses power quickly - generally noted by either a short power reserve, or if you haven’t noticed that not enough power there when you engage the chrono. There’s a watchmaker on OF who explains it well. |

I couldn’t tell you Stan - I suspect omega won’t respond to a query however. My advice would be not to sweat it. You have a 5 year warranty so any issues should identify themselves prior to then. After that, you are near enough due a service anyway when the offending parts will be replaced anyway. If your watch is running accurately and keeping a decent power reserve then you should be all good. And even if the worst happens, it’s about a 4 week fix so not too long.

I think if you purchased new stock July and up, the corrections have been made already. Make sure you don't receive old stock.

How many times we should wound the 3861 from no power to full power? I feel the 3861 is much stiffer than the 1863.

Mine was incredibly stiff at first and hurt my fingers but loosened up nicely after a month or so. As per the 1863, wind it until you feel the resistance. About 40 or so full revolutions I think.

Silly question, but what would happen if one were to leave the chrono hand running until power depletion. Would it damage the movement, etc.?

Even on the first parties the issue of power depletion is very rare. Now it does not exist at all. Very stable and exclusively accurate watch. |

reviving this old thread but seeing if I have an issue or just paranoid.
Just picked up a 3861 pre owned card dated December 2021 (after the July 2021 "fix" but not clear when watch was produced). I wound the watch about 30 times and it kept great time. About 30 hours later I ran the chrono and after about 58 seconds the chrono seconds and the watch seconds both stopped. As soon as I disengaged the chrono, the watch ran again. I wound it up and started the chrono again, and its running and not stopping. Is this the chrono issue described here and on the omega forums or just an indication of low power reserve from not fully winding it from dead? |

I might be completely wrong here, but I have the impression that the problem is most likely to occur when the watch is close to depleted power reserve.
Have you wound it fully? I don't know if 30 turns of the winder from a run down state is sufficient to do this. To fully wind it you need to keep turning the crown until it won't turn any further with gentle pressure - this might be 40-50 turns of the crown and you will feel the 'stop' quite distinctly. I wind mine fully every morning (ie, every 24 hours) and this usually takes around 18-20 turns of the crown. So, when you say you wound it 30 times and then encountered the problem 30 hours later, the watch power reserve might have been quite depleted by then. Arguably the problem should still not occur, but low power reserve can be overcome by fully winding every 24 hours. As I say, I might be completely off-beam here and others might have more informed thoughts on the matter. Good luck with it. Stan. |

Wind it until it stops!

I have a manual wind reverso and the winding is so much smoother from the start that I know to stop winding when I feel resistance. I didn't realize the omega has that built in stop, so I was probably not winding enough and confusing the tighter winding resistance with a "full wind" |
