my BB are constantly running at +6secs a day. am trying to regulate it by positioning, but that way aren't helping. in the long run, will it affect the mechanism of the watch? thanks in advance dan.

Modern movements aren't as seceptable to positioning as older movements. Also, consistency is more important than daily accuracy. There would be no negative affect on the movement.

Threads like this will only bring out people trying to justify their purchases, and loads of anecdotal evidence. If a movement isn't COSC certified, you shouldn't expect it to run as such. Either buy a chronometer, or don't.

Personally, I prefer chronometers, and my Tudor wasn't keeping time within -4/+6, and was one of the reasons I sold it, but not the main reason. I've had very accurate Seamaster Pros, Planet Oceans, Submariners - and some not-so-accurate Pelagoses, Explorer IIs, and so on.

My Tudors do too, including the Black Bay. And, yes, I had Rolex too that run outside of those specs, at times.

My non COSC 14060M runs +3 per day and has so for the last 7 years that I have owned it.

COSC is a certification not a guarantee

That's it. I'm selling all of my mechanical watches and keeping only my G-Shock.

Not so fast cheeta! I was checking my rolex against my gshock every couple days to see how fast/slow it was running. Every time I looked they were perfectly in sync. Figured I had some miracle rolex keeping perfect time. So gave them both a quick check against an online clock to find they were both running +3

Yeah, this falls into the category of "anecdotal evidence." Your watch running great is all well and good, but it doesn't mean anything in the grand scheme of non-COSC watches.

COSC certified movements running within COSC specs are also examples of anecdotal evidence. Some do, some don't.

Well if I am spending Tudor money for a timepiece my expectations are that it runs within the time specs of COSC whether it is certified or not. A fine watch is not a fine watch unless it is accurate within those specs. Otherwise it is just a status symbol or jewelry.

Reminds me of a guy I knew in Vancouver in the 80's who bought a SS Rolex on a years layaway (translated - he really couldn't afford it - didn't own a car..) and when it stopped running (not sure why it did - it wasn't mine) he used to wear it out to nightclubs and house parties anyway - just to get the stares and occasional comments - even though it did not run!!

Most all mechanical movements made today could with careful regulation match or exceed the now quite antiquated COSC test.And being a certified Swiss chronometer is not the holy grail of watch making.And most all Rolex watches will in there life need some sort of regulation.And the COSC certification is only at the time of testing the bare uncased movement.It does not guarantee it will run to that spec for life,but with normal routine service Rolex will do its best to keep it there with regulation.

And I am pleased to convey that out of six Rolex I have owned, and the two I still have - all have run within COSC! Omega, Breitling, UN's, IWC's all have as well. I would expect my AD to be able to regulate any new Tudor to achieve that accuracy without hesitation! If not....well...

Well most any good watchmaker could regulate it its not rocket science hardest part is getting the back off.Once on the timing machine they can very quickly regulate the beat rate.

What do you expect with an eta movement watch - you get what you pay for and a movement that in a month would be 13x30 390seconds fast or slow (6.5minutes) is a complete joke. I'd never buy a watch with those stats! A Rolex COSC movement is 99.9999% accurate.

Gaining COSC status means little to Rolex, Omega, Tudor and other top selling brands. Doubt more than 2% of buyers know or care. Of course, here @ TRF, 100% care about actual performance, not alphabet soup.

But COSC does serve a valid purpose for those people trying to break into the game with their own movements. It serves to validate the ability to produce accurate movements.

Tony-GB · 25 July 2013, 05:55 AM

As part of Tudor's rebranding, they are going to copy Patek by inventing their own quality seal. Patek Philippe uses PP & Tudor will use Tudor in Time. So if you see TiT on the rotor, you know it's a newer model.

Perhaps the Black Bay that they had in hand was off by that much, some watches are, regardless of their "certification"...

If it were mine I would take it in for proper timing and not assume that no COSC certification has anything to do with it's capabilities...

Yes it's real - really slow or really fast

FLY-DOG · 25 July 2013, 09:29 AM

IMHO COSC certification is advertising hype..... my 1969 Air King (not COSC Certified) is accurate to within 1 second per month and both my COSC certified Subs are 1 1/2 to 2 seconds fast per day! All are serviced and regulated but the Air King is my only Rolex that is that accurate. I could probably get my subs closer if I were to leave them for a long term testing and adjustment session with a competent watchmaker but the cost to wring out those 2 seconds per day and get them close to the Air King accuracy might not be worth it. I can live with anything within 2 seconds per day.

Cosc thing is "fixed" IMO. Marketing...

I have a non cosc oris dermeistertaucher regulator that was running ridiculous accuracy.
+15sec in 45 days or something like that. Can't remember. I had to triple check it because I couldn't believe it. And I originally thought that was impossible from a non cosc

eeh100773 · 25 July 2013, 11:35 AM

13 seconds off? Let me guess, you checked it against your smartphone. Not trying to be a wisea$$ here, but does a minute and a half a week really matter?

Haha, really? For some reason I assumed the G-Shock would be exact. Maybe I should get a microstella tool and regulate my Casio...

No, but 6 minutes a month do!
