Who has a METAS movement that is losing time?

If worrying about a watch losing a tiny amount of the 86400 seconds there are in a day is important to you then get the watch checked out. Personally I would just wear it and enjoy it, adjust the time on the first Sunday of each month and go again.

Life is way too short to worry about a couple of seconds going astray on your watch, you have a stunning time piece, enjoy it.

Bought an Omega PO 8900CAL 2 weeks ago and the watch ticks -2spd. I noticed it doesn't gain time whatsoever in any of the positions when resting overnight. On wrist it loses -2 up to -4spd. So, for me, it loses time constantly in AVERAGE (I know some people really love being specific here).

That for me is out of spec for METAS. Do you agree?

I will give the watch a bit more time and if it doesn't change, I will take send it in for regulation as a warranty claim.

In order to determine if it is in or out of spec, detailed tests need to be done on a timing machine under controlled conditions.

I had the same thing with my Cal.8800 SMP. I went to the boutique and had the watchmaker regulate it to match my wear habits. Went from -5 to +2 average.

I think Omega opened a pandora's box when they went METAS vice sticking with COSC. I'm sure they saw it as a brilliant marketing strategy, the ability to advertise a higher level of testing and precision. Problem is, that's what the end user will come to expect in real world use. So, where as before, a watch certified cosc may run at -4 spd, while not ideal to some, is still within specs and 99.99% accurate. When the watch is advertised as METAS certified at 0-5 seconds fast, people all of a sudden expect just that. The -2 to -4 spd or 99.99% accuracy isn't enough.
I would be interested to know how many get sent for warranty because it's a couple seconds slow per day...

5 second delta focused on +2.5 vs a 10 second delta based on 0... ( or what ever I am too lazy to look it up exactly.)

The reason they bias to the + is that it is easier to pull a crown out for a second and hack the watch to align it if its fast. If its slow its a much longer process to set the watch to the correct time.

Omega hasn't "stuck with COSC" for a very long time. Their tolerances on chronometer watches prior to METAS were -1 to +6.

I disagree. Despite the fact that the watch can perfectly pass COSC and METAS standards on a test bench, customers could still be a little upset if a watch doesn’t produce the advertised figures while on their wrist.

I think it’s good customer service that OMEGA even regulated my well-performing watch to meet those advertised figures.

Any good watchmaker will. If you present data and ask for "adjusting to wear", why wouldn't they?

Are the METAS standards similar to Grand Seiko's standards?

Does GS test their watches with a 15,000 gauss magnet? I doubt they do...

It is so incredible to me that a mass produced mechanical device can be made so accurate through technology. I remember back in the early days of forums (early 2000s), mostly anything within about 10 seconds or so was considered good for a vintage watch. It is amazing how small the deviation is over 24 hours and the variation in deviation by day, even across positions. Just amazing.

No. I don't think they do any magnetic tests. And their "anti-magnetic" watches are all 1000 gauss, although they list them in amps/meter.

Well, there you go - the specs are not the same then.

I would imagine a magnet would seriously screw with the Spring Drive movements, the escapement is an EM brake.

That would be 79,600 a/m @ 1000 gauss.

without the magnetic tests the GS test is similar to COSC with one more postion.

I would imagine the parts are also settling in and that there will be a deviation over time as parts wear in and lubricant starts to settle.

I certainly agree with your theory based on my experience with my 2018 SMP 300m Diver. When I wear my watch occasionally or less than 10 hours, I noticed it lags approximately -1 spd. However, if I consistently wear my SMP for 13-16 hours daily, it averages +1.4 spd. I contacted an Omega technician last month about my SMP slowing down and he explained all Omega automatic watches needs a specific amount of rotations daily to maintain its timing. See the following link for details: https://www.omegawatches.com/fileadmin/Customer_Service/calleo/faq/FAQ-watch_winder_EN.pdf

For those owners experiencing a loss of time, perhaps try wearing your watch more than 10 hours daily and hopefully, the time loss will be resolved.
This is normal for all mechanical watches that are not a Tourbillion, the balance wheel will not be consistent in amplitude in multiple positions. Also over time a watch will fall out of regulation. Honestly most of the non chronometer ETA based Swatch group watches are +6 or more. Don't get me started on Seiko. +1.4 is almost god like.

I bought two identical watches just different colors, my white dial ran as it should while my blue dial was -7 after 3 days, the website said -5, took it to a boutique and they told -5 is acceptable, but they also told me that it’s important how you place your watch when not worn, if you place it dial up you lose time, if you place it face down you gain time.

If that doesn’t work the in house tech can fine tune it for you, heck when he placed the watch in his machine it showed my watch was losing -11, he got it down to -4
