hi everyone
i have purchased my seamaster at 8900 at the end of 2022 from geneva airport and it is my first omega, i really like the piece and usualy have it on my wrist on daily basis. first 2 years accuracy was excellent but almost for 2 months accuracy has severely broken. when i adjust my watch in accordance with my phone it falls behing almost 2 minutes within hours range, and following 3 minutes deviation occurs around day 2 and 4 minutes deviation occurs around day 4. in other words there is consistency for falling behind but not in a linear form.
to be honest there has not been anything unusal to it, has never been serviced or opened. i am feeling disappointed about the case, of course you will suggest to have a service maintenance but maybe some of you guys have some words apart from the obvious one.

Should be under warranty, so take it to Omega...

I’m not familiar with this particular movement, I believe it is generally recommended to wind most automatic watches manually before relying on the autowinding alone.

That would be a good place to start. But wearing it all the time "should" keep it powered.

Give it a full wind and wear it daily for a few days and see if it's any better? It definitely should not be off by this much. Good news is it's still under factory warranty. It should come back good as new.

Hi, you're taking about the 8900 caliber, the one who Omega claims that it's the best three handed movement in horology, well I was nearly pulling the trigger a couple of years ago, but then I decided to switch my thoughts for a ZENITH Defy skyline also a three handed movement caliber 3620 with the small seconds at 9'oclock and about 2600CHF more expensive than the aqua terra and I can tell you it may not be so famous as an Omega is but concerning the quality of the movement, there's NO chance that Omega can even get close to the precision of my Zenith, so in other words don't let Omega service your watch try to get rid of it by selling it and save money for a ZENITH I'm sure you'll find a model which you'll like sorry not giving you the suggestion you might I could have given. Bye

I have a PO with the 8900 movement and have not had any problems with it. I rotate wearing it along with my other watches so it's not a daily wearer, but I wear it very often. I always give it about 20-30 winds and it has never had an issue. I don't know why some people are hesitant to wind their watches; they are meant to be wound and (in the case of the 8900 automatic) cannot be overwound. If there are still issues it should be under warranty if it is new.

thank you everyone for the responses including mr zenith 😀

that was why i have registered and posted my question here. to be honest i was not aware that i could wind my watch manually since the crown is a screw one, but once i wind it manually as the way it should be, accuracy restored the standart levels immediately.

very appreciated for your help.

Sometimes, if you are less active for a period of time, automatic winding may not be enough to keep the watch fully wound. And a movement generally keeps better time if the mainspring is reasonably well wound. It doesn't have to be fully wound, but most movements start to deviate from good timekeeping when the mainspring is reaching the limits of its reserve.
