Calling all Cal 9300/9301 owners - how accurate are your watches?

路I bought a new De Ville Chronometer, model no. 431.53.42.51.03.001 with the 9301 movement in late April of this year. It has been worn almost everyday since I got it (I love it) but it has consistently been running fast +15 to +20 seconds a day. I let it stop having used its reserve to see if things improved afterwards but there has been no change in how fast it runs. It has never run slowly and the best day to day performance has been + 7 seconds for a couple of days.
So while I acknowledge that it is not "broken" it is not within COSC or Omega's own tolerances for a Chronometer. I dearly love the watch and I feel that it only requires a slight adjustment but that would mean potentially up to 8 weeks without the watch (as advised by an official Omega Service centre) as various positions and tests would be required and while it comes with a 4 year warranty, when I reached out to Omega they were of the view it is not a fault (which I can understand, under performance while keeping time in excess of 99.9% is a disappointment not a defect) I cannot help but feel that it should be better, because it has been tested to a better standard that it is currently delivering.
Can anyone advise as to what I should do? I am based in Ireland for those wondering, in Dublin specifically.

It is most certainly a fault that they should correct under warranty. If you have an Omega boutique located near you, you may be able to get the timing adjusted there depending on how the boutique is staffed, but if not then it would have to go to a service center. But there is no doubt it's a fault...

路My 28 year old Rolex Date-Just is consistently minus one second per day, week after week. I could just as easily adjust it to gain one second per day, but why bother? No other watch in my collection gives me such precision, or consistency. My two 28-year old Speedmasters come quite close. Both within about one minute in two weeks.

路My DSOTM had an incredible +0 seconds dial up. I don't remember the other positions but it wasn't so bad.

路To answer your original question....I have no idea. Really, no idea. I know they are close and that's good enough for me.

While I have not timed my Speedmaster co-axial for accuracy, it runs about a minute fast per month. Well within COSC standards.

路I'm puzzled by watch owners that expect quartz accuracy from a mechanical watch, especially if the dial bears the "chronometer" moniker.
Some chronometers perform better than others while remaining within "chronometer" performance standards? Shouldn't this be satisfactory? Should it be cause for a "panic" attack?

路I observed my Speedy 9300 over the course of about a week recently and found an average rate of -0.8 s/day. Happy with that 馃憤

路My Ti Planet Ocean 9300 ran +2 sec/day for over a couple of years after I got it, and then jumped to +6 or more last December. Omega regulated it down to +0.8 sec/day (with very little delta or variation from day to day) and it ran between +0.7 to +0.9 sec/day until March of this year.
But then 3 months later in March it jumped to +4 sec/day, but it still has very little delta in positions or day to day variation. It's not magnetized, and my watchmaker says it looks "clean" on the timegrapher. Over the past 6 weeks it has remained between +3.8 and +4.6 sec/day consistently, with an average of +4.1 seconds. I've gained only 172 seconds in 42 days.
My 4 year old GSOTM runs a consistent +2.5 sec/day with little variation, and my 1 year old GSOTM runs +1.5 sec/day with very little variation. Those are my three 9300 based watches.

路My Speedmaster 57 Co-Axial holds steady at +1 second per day. I鈥檝e just bought a brand new SMPc 300 last week and, early days yet, but it's running at +8 seconds per day. Not sure what the limits are for a 2500D or whether it鈥檒l settle down after a while.

路My GSotM runs +0.6 seconds/day. Extremely pleased with that. I鈥檝e found placing it face down overnight keeps my 9300 from running a little fast. Conversely, placing it face up seems to make a real difference on my watch. Worst I鈥檝e seen is +1.8 sec. Fabulous cal!

路My speedy 9300 is about +1 s day and surprisingly better than my METAS 2018 seamaster.
