The Breitling Watch Source Forums

The model number of the watch establishes that it's COSC, no way that the certificate was a 'mistake'.

Not totally sure about the shock tests, but I suspect it's to test consistency of accuracy, especially as the frequency of the quartz is so high.

Go ahead with all the material in this post, mail it to Breitling UK with the repair history 3 days after You have sent them the watch via Your AD (don't forget to add repairnumbers). When they don't react properly by either fixing the problem or exchanging the movement, You should go there and beat the sh... out of the service technician....

No way, that should work like that.

Next update.

I agreed with the AD that I would monitor accuracy over a month (as the factory in Switzerland would be closed anyway).

Using the USNO clock, and BTs speaking clock, since 10th August, the watch has lost 9 seconds.

I make that 1 second per 3 days, or ca 120 seconds per year.

Now - lets see what Breitling UK can do for me.....

Hey - progress at last.

After some further communications via the AD, during which Breitling UK repeated that my watch was within 150 seconds/year (it was around - 120/yr in fact) and therefore within (their) spec, to which I said "Please consult the COSC website where it will show you that it is not within the COSC spec...", they have...

<Roll of drums, and exciting tension raising music....>

Agreed to fit a brand new movement!

This was 2 weeks ago, so I expect the watch back in about a week.

Question is - which one will they fit? The one that I had (i.e. COSC compliant) or the SQ movement?

I will let you know when I get it.

Many thanks to everyone who provided such helpful and valuable advice!

They'll put SQ inside which is +/- 15 sec a year.

The current version of the movement is used as a matter of course.

You know, if one of my mechanical watches could keep time within 120 seconds a month I'd be happy. I have to confess that I snickered a little bit at the beginning of this thread, wondering who could be so anal-retentive as to expect their watch to be accurate within tenths of seconds a day, and moreover, would care. But hey, we are not normal people, those of us who spend thousands of dollars on wrist bling. And I totally agree - you pay that kind of money for a watch, and they promise you that it will be accurate, then by golly it should be that accurate! Kudos to you for sticking with it and getting them to fix it. I hope the results are satisfactory when it comes back. BUSA has seen several of my watches, and I was happy up until the last time when they nearly buffed the serial number away into oblivion. You need a loup to see it now. That's just careless.

I probably would have accepted 120 sec/year if this had been the performance all the way through. But it was so much better up to the first service, only showing measurable errors after this service, and continuing after the 2nd service.

I did not expect them to change the movement, merely regulate it back to the performance that it displayed in the first 3 years of ownership (sure not difficult?).

I am taking tablets for the AR thing. I used to be far worse....

To OP - Hi - I have a B-1 SQ and am getting +4sec/year though since the last battery change it has drifted from that to maybe +5-6/sec/year - to be honest I haven't measured it recently - I think you should be well pleased with your new movement.

Wifey's Colt Oceane (COSC-certified SQ, bought used 2 years ago) gained 26 sec. since beginning of DST - 7 months. Outside limits but it's ok. since watch needs adjusting twice a year: beginning and terminating DSL. Never more deviance than .5 min.
Enjoy! Robertus

What is the yearly tolerance for SQ?

Same answer as you were given when you asked the same question in another thread this morning - viewtopic.php?f=1&t=24659

This is an old thread, I know, but I'm just seeing it now. In my opinion, the only reason to go with quartz is for accuracy. Otherwise why bother? If I had a Breitling COSC quartz (SQ or otherwise) that was keeping worse time than my mechanical watches, I'd want it fixed, too. I have a TAG Link, basic, non COSC quartz that I got in 2006. Back then, it was deadly accurate, +/- a second a month or so. It has since had a battery change, performed for free by the jeweler at the AD where I bought it, and has never been sent in for any servicing, and it is still just as accurate as when new. I haven't kept spreadsheet data on it, but I compare it to my atomic clock every now and again (which I, in turn, compare to time.com), and the TAG is always within a blink's time. If TAG can do it, Breitling sure as hell should be able to.

I'm sorry Tony hasn't posted any further updates. I would have liked to hear how this all ended up.

+/- 10 sec per year?

As stated in the thread that br549 linked to for you this morning Breitling say + / - 15 seconds, COSC says + / - 0.07 seconds per day.
