路The bent wheel is damage done after it was removed, and not the problem that caused your watch to stop. No watch would run at all with a wheel that looked like that. Possible it was dropped on the floor and stepped on or something.
The real issue here in this cropped photo I've made from yours:
You can see where the red arrow is, that a section of the wheel has worn and is quite a bit smaller than the section directly below the arrow. This whole section should be the same diameter, and should be a polished cylindrical shape. The wear here is obvious, so this is the problem that is addressed during the service, not the bent portion of the wheel.
This is a large amount of wear for just 4 months. I would typically see this sort of wear only after many years of service, running in a watch where the oils have long dried up. I suspect there is some wear on the upper part of the picot as well, above the bent wheel, but the angle of the wheel prevents me from seeing it.
Cheers, Al
Hi Al,
Thanks for your detailed explanation! I was also surprised that the watch failed after only 4 months (so only 120 days of wearing). I only used the chronograph once or twice (for a few minutes) so that does not play a role in increasing this defect. Iam surprised that not all watches fail after a few months, since basically they all contain the same parts, made from the same material, and gone through the same quality control.. Since you were curious about the upper part of the wheel I attached another picture showing the other side of the wheel..

路If it's helpful to add another data point, I just got my sapphire sandwich (received from Omega in July 2021) back from service today. I had the watch for 4 months before it started to exhibit the same symptoms described here. I dropped if off at the NJ service center late October, so they had it for 3 months. Here's a picture of my center wheel:

路路Omega Qualified WatchmakerExcellent photo - you can see the wear on the main plate side to the left, and the wear/discoluration on the bridge side to the right...

路It's funny that shares the same issue with 323x Rolex.

路路Omega Qualified WatchmakerBarrel issues, pallet fork issues, etc. Basically it's not good all around based on what I'm hearing.

路路Omega Qualified WatchmakerExcellent photo indeed.. Since I am not an expert but just an interested amateur: is the issue caused by an inferior center wheel, or by a lack of lubrication, or maybe something else? Thanks in advance for your explanation..
It鈥檚 the material used for the respective bushings.

路I鈥檓 about to pull the trigger on the new Speedmaster (before the rumoured February price increase). Should I stick with my AD who鈥檚 had stock since last year but may offer a small discount, or bite the bullet and pay full cost and buy direct from Omega鈥檚 website in the hope it would be a more recently assembled watch which will hopefully have the issue already resolved?

I鈥檇 personally buy direct for precisely what I would hope would be a decreased chance of encountering the issue. If you don鈥檛 yet know what the potential discount is, then I guess finding that out might contribute to your decision.

路Got my Apollo 11 50th in Aug 2019 and have wound and played with the chrono countless times to see if this issue is going to occur on my example. But it's rock steady with nary an issue yet. Still have 2 1/2 years left on the warranty so plenty of time for the issue to occur, but perhaps it won't.
Yes, I am the same ( but did not want to "jinx" my watch by posting ) .
My Apollo 11 winds smoothly and runs for well over 50 hours consistently, Keeps excellent time. And I have even let the chronograph run for 4-6 hours continuously with "NARY" a problem as well. But now I assume it will either break or just be repaired when routinely serviced.
This was my first Omega purchase . . . I love the Apollo 11, but even though my watch is still so good, honestly, I am a bit surprised and disappointed.

路I just bought an Omega Speedmaster on the 10th of January, and the chronograph has stopped, along with the whole movement twice. The first time was in the gym just after I'd fully wound the watch, the second time was this morning just before I normally wind it. Both times I turned on the chronograph and it stopped after around 5 seconds. Is this a problem? Do I need to send the watch back to Omega?

路Yes, it's a Speedmaster with the new 3861 movement in it. It's only stopped twice, so maybe it's not that serious a problem. It could be something else.

路So an update on my end. The good news is I took this into the boutique and they were able to get the watch returned to me within 4 weeks. However, they returned the watch with just a receipt showing it was given maintenance (the diagnostic indicated the movement wasn鈥檛 performing correctly). No replaced parts in a bag or anything. Is this normal? Should I expect that they fixed the brushing issue? It was obviously the same problem others have been having.
