Well, a new movement brings new challenges! This is normal! It was the same with the 1. Co-Ax movements in early 2000-years…

But this is not really an issue, if Omega soves the problem. And they did in the past with the Co-Ax. Even after warranty periode, at no cost. And they will do it here as well if it really is a failure of design… 👍🏻💡

Issue with the Omega Caliber 3861
By: Boris : July 14th, 2021-04:27
Hi all, I am unfortunately coming on this board to report a problem that seem to be affecting the Omega caliber 3861, first rolled out in the Speedmaster Apollo 11 50th Anniversary introduced in 2019, then in the Moonshine in 2020, and finally in the regu...
I had the same issue with my Speedmaster Professional

Hi Boris, I purchased a Speedmaster Professional, 3861 Sapphire Sandwich in October 2021. After 12 months it has developed the same fault. When fully wound, if you engage the chrono it comes to a complete stop. Its currently with Omega and they have quote...
Sorry to hear that and seems there is a solution so it will be resolved.

I owned both the Apollo 11 50th anniversary pieces since 2019 and haven’t noticed any issues….or yet? Is there a way to stress test it? I do wear the SS version quite a bit and sometimes I left the Chronos running for a day on both but neither had failed....
Thanks for a detailed report.

I’m surprised to hear this issue happening with a co-axial movement, which is supposed to reduce the wear and tear and extend service periods (albeit by working at the level of the escapement’s interaction with the balance spring, and not at the chrono pa...
I was thinking exactly the same thing
By: Boris : July 14th, 2021-07:26
What is the point of having a co-axial escapement, whose main purpose is to reduce friction / need for lubrification / service around this part if another part of the watch is overlooked and needs more lubrification / service. Any piece of equipment is on...
Thank you for this.

Luckily i bought the previous version, just when this came out.
I don't think it's this easy
By: Boris : July 14th, 2021-10:03
Some users have reported issues after 4 seconds, some didn't even use the chronograph function and the watch still stopped. It does look like a small bushing needs to be changed at the center wheel, and only watchmakers having access to these specific par...
design/quality control problem
By: golden hands : July 14th, 2021-11:15
the meshing of the chronograph wheels when activated to engage when the start lever is pushed by the case pusher is very very fine and if there is a problem identified by the omega watchmaker with the centre wheel bushing-not to tolerance or no perfectly ...
Thanks for the detailed explanations
By: Boris : July 14th, 2021-12:22
They mirror the understanding I had (at a much more basic and layman level than yours). I can't see through the caseback, unfortunately, as my watch is the hesalite version. I hope that's the only issue with the new caliber, and fixing the center wheel bu...
Appreciate the detailed post and warning.
By: MichaelC : July 14th, 2021-12:27
I wonder what % of watches released with the movement are having the same issue? Maybe this will become one of those situations that Omega updates on existing watches as they come in for service over the years (assuming they don't fail first like yours). ...
Impossible to know what % would be affected
By: Boris : July 14th, 2021-13:22
Pretty sure that Omega would have the number of watches with 3861 which have been returned to service with this issue, but I'm sure it's a pretty guarded information. I think you are right: Omega will probably update existing watches either when they fail...
Thks for the detailed account dear Boris…
By: S F : July 14th, 2021-13:14
I had mine since Jan21 and other then testing the chrono at the shop, I have not activated the chrono function since😅. However, I have been wearing it quite frequently and thus far no issue. Will definitely keep a closer watch now….. Hope your problem is ...
Have had similar issue with my Speedy 60th
By: JCF81 : July 14th, 2021-14:04
But it’s an older movement. The chrono would lock and “bite” and stop the watch totally. It was few weeks old fresh from Omega Boutique, so i had to send it in for warranty repair. They were able to fix it, work done not described to me. It is working fin...
why did they want to upgrade the omega cal 1861 to 3861?
By: golden hands : July 14th, 2021-17:37
i would be interested to know of what they wanted to improve. the switched chronograph will never work or be as reliable as a column wheel one so maybe they should think of bringing back the original omega cal 321(lemania 2310) the cost would be greater b...
I read those accounts of rotting bezels on Tudor BB Bronze
By: Boris : July 14th, 2021-22:49
Frankly I find that a lot more shocking than issues with a new movement which, annoying as they are, do happen relatively frequently. For the bezel issue, it's really a case of an aesthetic choice (bronze) completely compromising the intended use of the w...
My 50th Was In Service
By: enjoythemusic : July 14th, 2021-17:50
Yet it was due to being very hard to wind... and this has also been reported I believe online. Yes, soon thereafter the mainspring broke. They fixed it fairly quickly and happy with the service. Am not worried as I believe Omega will fix any known problem...
This morning
By: Weems@8 : July 14th, 2021-20:04
I noticed your thread. This evening i take time to reply. Why? I have a love for Omega. It hurts to read a Omega with problems. Yesterday i talked with a watch friend about Omega and how we love what they made in history till present day. He picked up a p...
