216570 out of COSC/Superlative spec

[sotsdisc]

Recently discovered WatchTracker and it seems my 3 month old explorer II Polar is running just slightly out of rolex’s -2/+2 spec. It’s running about +2.5 daily. I have tried various night resting positions and can’t get it under +2 no matter what I try.

It doesn’t bother me - I am not a crown/rehaut alignment perfectionist but do worry a little that if it’s starting out of spec it will get worse.

Do movements typically speed up or slow down over time or both?

Anyone think it’s worth a service? I could drop off at RSC New York but have read stories on TRF to avoid NY and use Dallas.

Thanks in advance for any input!

Yes

No

There are 86400 seconds in 24 hours, is it that important to you that you have a deviation of 2.5 seconds per day? The watch mechanism is subject to friction, wear, expansion, contraction, mass etc to can never be 100% accurate. IMHO no service is required.

cosc is -4 +6

so your watch is w/in cosc standards

[Ian Macdermott]

If anyone has ever said you are 2.5 seconds early for an appointment then yes get it adjusted

[rolexinfl]

Its fine, dont touch it.

I wouldn't worry about it. Dealing with the hassle of sending the watch in would annoy me more. Personally it would have to be off by 5-6 seconds a day on a new Rolex before I'd be annoyed enough to get it regulated.

And yes I do believe movements will speed up / slow down over time. All of my new watches keep better time than the older ones.

[Mr. Superlative]

Leave it well alone, it is absolutely fine just as it is.

[Dennisoul]

It’s running beautifully....enjoy your watch

[watchwatcher]

+2.5 is not even remotely close to worrying about IMO. And...as it's a fairly new watch, it may even settle in closer eventually.

Just monitor the watch occasionally and enjoy it.

I've often wondered how to track watchtracker for accuracy.

It has showed deviation on a gshock which otherwise matches my atomic clock.

The app can only be as accurate as the time source it links to .

Certainly not something to base accuracy on.

There is no such thing as superlative spec that's been on Rolex watches for the past 40 years.The term "Superlative Chronometer" is trademark of Rolex and has been used for many decades even on the 15 series movements. The addition of the word "Superlative" in front of the official designation of Chronometer is merely a Rolex marketing angle to give a more distinguished sound to the chronometer status of their products . As all watches that have earned the privilege of bearing the official Swiss designation of "Chronometer" have to meet the exact same C.O.S.C. standards. Any words added before or after the official designation of "Chronometer" are merely more marketing which Rolex is very good at.The bare uncased movements are still tested at the COSC to the Swiss chronometer spec of Average -4+6 seconds daily rate to get certification.Rolex then further tests to this new spec of -2+2 seconds daily rate.Consistency is the most important for any mechanical movement,and I am 100% sure that half a second difference out of 86400 will no effect on your watch or your daily life.You state you are not a perfectionist yet you post on forum for half a second hope you are not going to catch {CCTS} CONSTANT TIME CHECKING SYNDROME.Take my advice just wear and enjoy your watch its fine leave well alone,and get rid of the phone tracker app as its not 100% accurate..

Those are not the standards of a Superlative Chronometer Certification. Its +2/-2. However, i still wouldn't have it serviced, its such a small deviation that may even regulate over time.

There is no such thing as a Superlative Chronometer Certification, to meet the Swiss chronometer standard, all movements tested at the COSC have to meet the same standard for movements of Rolex size Average -4+6 seconds.

True!

I shouldn’t have said certification, that was poorly phrased. Do you believe that superlative chronometer leaves Rolex within cosc spec only? If so, maybe you need to do some homework.

That word superlative has no real meaning its been on Rolex dials for over 40 years, plain and simple marketing nothing more,yes Rolex now if its true re-regulates on a machine to this new spec of -2+2 seconds.What does this mean well much like the COSC test at time of testing the movement met that spec.Now Rolex must have some sort of machine to test many at a time.As if you send a single watch back to Rolex for regulation it could take around 4 weeks plus before getting watch back.Plus the simple fact when tested on a machine, is quite a different story to having the watch on your wrist with the many many daily variables.Like the earth's gravity,mainspring power reserve, metal expansion and contraction, temperature variations, subtle changes in lubrication and friction, shocks, and so on, no mechanical watch will keep 100% perfect time.

Ok fair enough - I posted what cosc standards were, you corrected me w/ Rolex' Superlative Chronometer specs - we were both right.

Enjoy your day!

Yes

What homework should we do? A marketing term is just that and can be found all over the Rolex website as just that, marketing.

But Rolex will be happy that at least someone is buying into the massive hype train.

Totally agree, perfect time is for Quartz movements. I think COSC is close to COSC is extremely solid considering the amount that these watches go through on a daily basis. To gain only a few seconds a day is really impressive.

How Rolex Lists on their site:

CERTIFICATION
Superlative Chronometer (COSC + Rolex certification after casing)

If their deeper testing of the movement to a tighter spec is hype them i guess I'm bought into it.

The time with the watch off the wrist isn't worth the change to the timing accuracy imho. You'd never notice the difference it you weren't looking for it. If it ain't broke don't fix it.

[polaris72]

Do not send the watch anywhere. Just enjoy it.

Yes it does bother you or you would not mention it...
My input would be it's broke........if it loses more than a 10 seconds a day....

.if you want proper accuracy buy a £20 quartz watch...if you want style and class buy a Rolex but don't expect accuracy of an atomic clock or a quartz
