Power reserve test on my new 3861 Speedymaster Pro.

Yes, sounds familiar. If I'm thinking about what you're describing, you probably have quite a few turns left. Think mine got to that point around the 60th turn or so. It gets tight and after each turn the crown releases backwards a little.

My advice is to let it run all the way down, then start winding and count each turn. If you are around 55 or 60 turns, you haven't found the hard stop. Once you get around 70, you're getting close. When you truly hit the hard stop, you feel it where it will not physically let you turn it further.

You will not damage the movement because it's designed to be wound fully. It will definitely let you know when the spring is fully wound.

I went 102 turns from dead yesterday at 5am.
I feel the resistance starting at about 70 and keep going.

The hesalite has just gone 50 hours and still running. It’s just interesting that it has taken 3 times of starting from zero to get it to perform to the specifications.

More likely to me that the hard stop wasn't reached the first 2 times.

This.

You can save yourself the headache of counting and just wind until you hit a literal hard stop. Feeling resistance is going to happen as you’re winding up a spring. You’ll know it’s fully wound when you hit a stopping point.

Ok. I'm getting impressed now. still going after 59 hours. But the fact remains that my white one did have a problem that Omega recognized and will repair.

I wound it exactly the same way three times, got 43 hours then 48. Now over 59 and counting, thus my break in question.

Would be very strange if it passed Metas and still break in time would be applicable.

There is no 'break in' period for how long a watch will run on a full wind. As others have mentioned, it is most likely you stopped short of hitting the hard stop. That's natural for a new owner who doesn't want to damage his new watch, but once you get comfortable with the winding situation you'll go deeper and deeper into the process until you finally get to a full winding, full stop situation. From then on you'll be able to comfortably wind it until you get to a hard stop.

66 hours 45 minutes. Pretty good, but this is why I am asking questions and posting results. There times I have wound it EXACTLY to the stop, and every time it ran a different number of hours.

You either are incredibly unlucky and got two lemons, or you just aren't winding them fully. I would wager $1,000 on the latter.
It’s back. Probably the first rebuilt white one.

The watch has received a full service. Looks like they replaced the center wheel, a bushing, plus the entire mainspring barrel. Also, all the seals, the spring bars, and the crown...

Could it be the issue that was first reported on the A11 50ss?
Omega has made a modification to the 3861 movement by changing a bushing in the movement to a replacement made of a different material, and has also altered the recommended oiling procedure to remedy the issue. Within a short period of time all new 3861 movements should have that change implemented from the factory and any that do have issues should be covered under warranty and will likely be upgraded at the time of their first service.

I did not know about that issue, but I would have thought that one this new would have had the new part. Anyway, It's back and I am happy.

Can't tell without seeing a macro of the center wheel.

Thanks for all of your advice on these. I can take a super zoomed picture of it and post that.

Back to the point, I posted in the other thread but the rebuilt white one went 60 hours 50 minutes and the hesalite went 63.5 hours. Both way over the promised 50. The white one is harder to wind now than the other one, not surprising I guess.

Every time you comment on Speedy reserve I can't help but note that you have bought 2 new ones and complained about the reserve on both due to operator error, as recounted in your earlier posts. You claim that because they serviced the white one they acknowledge a fault. I know from experience they perform a complimentary service to make a troublesome recent customer go away. I hear you’ve bought a FOIS, I look forward to your stories about the reserve on that, though the straight lugs are much easier to wind than the Pro models so perhaps you’ll manage this time. Perhaps third time will prove lucky. Or perhaps some AD will be unlucky and have to send it away. Let’s see.

The new black one was not sent back.
