Who has a METAS movement that is losing time?

My SMP 8800 loses about -0.5 to -1sec/day. It’s about 2 months old. Started with +2 sec/day. Randomly, it may gain a second here and there. Not sure if I should send it to Omega now because in the grand scheme of things, -1 sec/day is crazy accurate. Maybe when it goes way off spec or before the warranty runs out I might go ahead and send it in.

Interesting how after a few months the movement starts going in the minus direction. Have you been wearing daily?

It's amazing to me that a mechanical device, with intricate and often delicate parts, and such tight tolerances, can be so accurate. Especially considering it is strapped to someone's wrist where it undergoes constant and unpredictable movement, and some extreme acceleration (and sometimes deceleration off a door... ).

Even if the variation between the worst positions during METAS certification is 15s per day, that's only off by 0.017%!

Except that neither POinNY or I's watches have demonstrated that supposed average... and if this is indeed normal behavior, then it just seems misleading to say that the METAS calibers are "tested with precision criteria of 0/+5 seconds per day". Doesn't that seem to indicate that your watch should run within those specs?

As I mentioned earlier, I'd totally rather my watch gain 4 or 5 seconds per day rather than lose just half a second. The fact that the real world performance of the watch is outside of what it is supposed to be certified for is quite frustrating, especially given the additional premium for a METAS/Master Chronometer watch.

And I found this thread because I bought a new Aqua Terra. I've had it 3 weeks now. It consistently loses 2spd regardless of what I do - wear it all night, put it on a winder, lay it down crown up, crown down, on its face . . ..

It is pretty disappointing to me because I bought an Omega specifically because its alleged accuracy. I thought I was going to buy a JLC, but as I researched, I was taken in by the technology.

Adding insult to injury, I was given the wrong box from an Omega Boutique and don't have access to the original testing report for the watch.

I have cards, just for the wrong watch! They are purportedly taking care of it.🤬

I’m looking for some feedback from those who have PO 8900s/8800s and SMP 8800s and notice their watches losing time over 24 hour periods.
I've had a total of 3 Planet Ocean 8900s: two of them were -0.5 and -1 sec per day and one was +1 sec per day. All were bought new. Because two of these lost time after 24 hours, I'm chalking it up those two having much tighter tolerances than the other one that gained. When I registered these watches on the Omega website and looked at the individual performance results, the two watches that lost time over a 24hr period always had an average that was closer to 0, while the one that gained had an average of 4.6 sec per day in a range of 0-5 seconds.

I'm think the loss might be normal because my first PO 8900 that lost time, I sent it over to Omega for diagnostics and testing. They had it for a week and reported that it was within METAS specs, but on my wrist that was never the case. I've seen numerous other people here and watchuseek.com with METAS movements post about how their watches lose time in a 24 hour period, usually ranging from -2 to -0.5. I find it odd because theoretically a METAS movement should never lose time. But I also know that if the watch spends most of its time in a slow position, that will skew the accuracy.

With my latest PO 8900 purchased only a week ago, I notice it'll lose 1.5 seconds over 15 hours of wrist time. When I set it at night, crown up, it'll gain 0.5 seconds back so the total loss over 24 hours is 1 second. I think crown up is the "fast" position for this particular watch, but the only issue is that it doesn't make up for what it lost fast enough. I'm hopeful this will improve since it's still a new watch, but I've been reading that "settling in" and "break in" periods for mechanical watches are just myths.

Is there anyone else with a METAS movement noticing a loss over 24 hours?

An easy fix is to get more watches than you need. That way you’ll be negligent on checking the specs for each watch and let them wind down, which will mean you’ll have to reset it back to time.

That is my technique exactly. Just as with risk, I find that spreading one's OCD tendencies across a decent stable watches reduces the amount of detailed scrutiny that any one piece must weather. All of mine are a little bit slow or fast, a little bit scratched, and a little bit loose or tight. Makes for much less stress overall.

I have a 2018 SMP and have had it for about a year. In the 1st few months I’d get +1/3 spd wearing and +4/6 spd in any position at rest. Almost a year later I’ve noticed I now get -1/3 spd wearing it, and 0/-2 spd at rest. I called omega and spoke a few reps who were a little unenthusiastic at best, but they are sending a shipping package. I don’t even want to send it out, but I’ll see how things go. Anyhow, kind of disappointed as it is stated that it is not supposed to lose time.. My aqua terra has been consistent for over 2 years at about +2/4 per day mixed wear and rest. anyway my 2 cents.
