The tolerance for average daily rate for the 8800 series of movements is from 0 to +6 seconds per day.
So what you were told was certainly not correct.
I agree with you, but then why did omega give me those numbers?

How the hell do you account visually for less than a second per day? Even with an atomic clock the variances on your own processing of the hand movement may account for less than a second...
Anyway, just curious. I would certainly not be concerned with less than a second. I would not even be concerned with a second or 2. Since it is slow rather than fast I am sure they can regulated for you somehow but an automatic movement will always have variances over an atomic clock. always.
Last thing I would consider is what are you calling a day? and could you test on a 2 or 3 day basis? the watch will act differently while on your wrist than sitting on your night stand. The few times I have measured loss (just recently as I was curious about my 32XXX Rolex movement watches based on another thread) I measured on 24 hours, 12 hours on and 12 hours off roughly. If there was a significant loss or gain I would extend the period one more day or two. Only one of my watches had a significant gain of 4 seconds (explorer) All the others where within a second or two.
I enjoyed the process so now I am testing the Omega (AT was spot on prefect after about 6 years with me) and IWC collection.
Anyway. I'd take "less than a second" any day of the week and twice oil Sundays.
Likely because a customer service rep had no idea about watches...

I am basing my -.18 per day over the last 11 days when I reset all of my watches for daylight savings time. I am not new to this hobby as I have been in this hobby since 1992. My new seamaster 300m is part of a 9 watch roatation is on a wolf watch winder when not in use. I’ve said my piece, discussion over.
If so then why do they claim on their website that 8800 series is METAS certified with criteria of 0/+5 ?

Ok, I did my homework and according to the METAS requirements (PDF here https://www.metas.ch/metas/en/home/dok/rechtliches/Zertifizierung_Uhren.html) if movement 8800 falls into Ib category (i.e. fitting diameter D is between 20 < D ≤ 26 mm) then indeed the expected average daily precision P is 0 ≤ P ≤ 6.
