To anyone who has actually had a modern Omega for 7 years or more

I bought a 2006 model Planet Ocean with 2500C movement back in 2011. It was someone else's daily wear and then became my daily wear until around 2019. It was never serviced for the first 13 years. Accuracy and reliability were great throughout. I ultimately had to get a full service because I dropped it on a tiled floor 😲 My watchmaker charged extra for servicing a co-axial movement, but no major parts needed to be replaced and it's continued to run fine since this time.

I bought my 2500D SMP Diver in fall 2014, and gave it about 60% of my wrist time from then until the summer of 2020, when it unexpectedly stopped a couple of times (maybe two or three times over a period of about three months). I decided that it would be smarter to get it serviced sooner rather than later, and it went to Seattle for a full service in August. I got it back in four weeks, and it's run perfectly ever since.

I have an AT with a CoAxial 8500 I bought new in 2016. Keeps excellent time and is very durable.

I wish the same can be said for mine. Bought mine brand new in 2017. Now 6 years later, the quickset hour hand is already giving issues. It doesn't jump the hours when setting the time/date, I thought it was a non issue, until i discovered that the hour hand would get stuck a couple of hours before midnight while the date change is in progress. I would have to forward the hour hand manually and change the date, only then will the time move as per normal. But the hour hand would get stuck again around the same time before midnight once the date change is in progress. Very disappointed as my blue Aqua Terra is my favourite piece. Will definitely take it in to the service center soon. Out of warranty already so that sucks.

I have a '57 with a 9300 movement that's probably going on seven years. It still keeps rock-solid time and the upper shock protector reservoir is doing well, but it spends most of it's time in a box.

I’ve always wondered where exactly the co axial escapement falls in terms of horological ideas. I feel like the original idea is that it does decrease friction. It sounds reasonable that it would, as it technically is distributing the amount of friction over different surface areas. I also do feel that it’s a great invention.
What i wonder is, does this fall into something like the realm of tourbillons, impressive, but little more than a complication for complexity sake. Is there evidence to show that there’s actually any benefit to co axial, other than just being another accomplishment?

Hi. How many of you guys have actually owned a coaxial Omega for at least 7 problem free, service free years?

And if so, which caliber coaxial?

I'm trying to draw some valid conclusion by asking owners, or watchmakers, who have had first-hand long-term positive (or negative) experience.

(Most information on these movements is hypothetical and unfounded, by cynics or by enthusiasts. They seem to form opinions based on internet hearsay. "Authorities" are usually businesses).
My Seamaster 300 MC with cal. 8400 is still running very accurate since 2016 without any service so far.

Es gibt viele Berichte, dass die Kupplung stirbt. Ich denke jedoch, dass dies nur durch manuelles Festlegen des Datums geschieht. Ich habe viele Uhren und muss das Datum immer manuell einstellen, da ich eine Uhr nie länger als 2-3 Tage trage.

Interesting. Now that you mention this, I do think I remember reading or seeing somewhere that the time or date should not be adjusted within a certain window near "midnight" in watches with a date window, but I didn't look into it because I have an 8400. Something puts additional strain on the movement during that time?

Co-axial? Don’t have one, don’t want one, and never will! Call me a troglodyte!

Interessant. Nun, da Sie das erwähnen, glaube ich mich zu erinnern, irgendwo gelesen oder gesehen zu haben, dass die Uhrzeit oder das Datum in Uhren mit einem Datumsfenster nicht innerhalb eines bestimmten Fensters in der Nähe von "Mitternacht" eingestellt werden sollte, aber ich habe nicht nachgeschaut, weil ich eine 8400 habe. Etwas belastet die Bewegung in dieser Zeit zusätzlich?
Bei den 8x Kalibern gibt es eine schnelle Einstellung der Stundenzeiger. Keine separate Datumsfunktion.

Ich besitze 3 Uhren mit Kaliber 8500. Alle starben nach 3-6 Jahren an dem gleichen Fehler. Stündliche Radkupplung defekt. 1x Garantie. 1x 650€ die 3.250€ auf Goodwill. der weiße ist seit 4 Monaten bei Omega

You must use the quick change hour function a lot then. In the future, I would recommend using it less if possible - for example if you can turn the hands back in time to get to a date faster than turning it forward in time, then do so.

This has nothing to do with co-axial. The GMT's that were made before co-axial had the same failures...

Thanks for the context, Archer. I hadn't really thought about this, but there literally is a clutch, as Schnorchler stated. The fact that it would wear out doing its job- letting the rest of the watch continue to move while you adjust the hour hand, makes sense.

Have had the previous non-wave SMP300 with the 2500D movement since 2019 work flawless since.

My modern steel Ploprof had the same issue as the video above. Omega fixed it free of charge. I have owned it 8 years, bought second hand.
