Who has a METAS movement that is losing time?

Your description doesn’t match the slips. The first slip appears to be not fully wound based on the lower balance amplitudes, and the average rate is spot on at zero.

The second slip appears to be fully wound (higher balance amplitudes) and is showing an average rate of -2 seconds per day.

The Deltas on both are 3 seconds over 6 positions, which is very good. The watch needs to be sped up, but when they do this make sure they don’t introduce a poise error, which would increase the Delta...

Just be clear, there is no “-0.2” rate anywhere on those slips. One slip has the average at zero, and the other at -2 seconds.

It makes no sense to me that the balance amplitudes would go down when the watch was fully wound, so at this point there’s not much I can say...

It could be a faulty machine, it could be a faulty watch, it could be an undisclosed magnetic source, hell, it could be aliens from the planet Tharg. What I'm taking away from all this is that despite saying on page 2 "But, I’m fine with -1 sec per day", something is still bugging you. I understand the desire to hold Omega to their (perceived) accuracy parameters, but it seems to me that you are now on a path where your watch will always be the one "that doesn't run quite right" and you'll never really enjoy it.

I'm not entirely unsympathetic, but if your ownership experience has been tainted, then the only two logical steps would seem to be a) contact Omega, explaining your situation and asking them if or how they would like to remedy the (perceived) deficiency in your watch's accuracy or b) dispose of the watch.

There is a third option which is to take on board all the good advice and explanations, adjust your expectations and enjoy your watch for the excellent (and pretty damn accurate) timepiece it is.

Personally, I only adjust watches (apart from my radio controlled Casio and other quartzes) when they have run down or when the time seems to be out by a minute or two. I'm not really concerned with atomic clock accuracy. For the last 10 days or so I've been wearing a 2255.80 with a 1120 movement and haven't felt the urge to reset the time once. Is it bang on in terms of accuracy? - no real idea - but it's not gaining or losing time to a degree that makes me want to fiddle with it. YMMV.

Whatever road you go down, I hope you come to an endpoint that brings you some sort of satisfactory closure.

You know, this was really well said and well thought out. I do have an issue with OCD where material possessions need to be perfect and out of all my hobbies (watches, cars, motorcycles), I see this OCD taking the enjoyment out of them. For example, when my AD called me that the watch had arrive, instead of being happy and excited like most others would be, I had a sense of fear - would the watch have a dust spec in the dial, would it not be accurate, would the serial numbers not match the paperwork, would the lume on the markers not be even throughout? Then when all those boxes are checked off, I can breathe a sigh of relief. But then the other questions pop up - will it pass the 60 hour power reserve test, etc?

So even before you replied, I thought this situation would be an excellent way for me to challenge my thinking and take the watch for what it is, which would be your option 3. So that's what I'm trying to do.

However, things are a little different now compared to when I started this because now I KNOW something is up since the Omega boutique kind of confirmed it as well. But still, I will try to move past that and take it for what it is. Nothing is perfect and trying to find that perfect can be costly and time consuming.

It’s not the same spec for every movement...

Ive been following this thread and I pulled out my 60th Anniversary SM300 on Sunday. I’ve worn it 24 hours a day since then and it gains about +2 per day.
