Redefined Superlative Chronometer Certification

[Rookie52]

Hi All,
What are the thoughts on this? Does this guarantee apply to any and all models with "Superlative Chronometer Officially Certified" on the dial? Even those many years old?

From the Rolex site - This exclusive designation testifies that the watch has successfully undergone a series of tests conducted by Rolex in its own laboratories according to its own criteria, which exceed watchmaking norms and standards. The certification applies to the fully assembled watch, after casing the movement, guaranteeing superlative performance on the wrist in terms of precision, power reserve, waterproofness and self-winding. The precision of a Rolex Superlative Chronometer after casing is of the order of −2/+2 seconds per day, or more than twice that required of an official chronometer. The Superlative Chronometer status is symbolized by the green seal that comes with every Rolex watch and is coupled with an international five-year guarantee.

No offence, but how would that make any sense?

Do you think because they changed the definition of what it meant by "Superlative Chronometer" older watches are going to magically regulate themselves to -2/+2?

I don't think that. I just found it interesting that apparently Rolex redefined the parameters to -2/+2 in 2015 but other than that, there isn't much more detail.
Which models does this cover? Only the ones released today?

Everything that comes with a green hangtag was my understanding, correct me if wrong.

Rolex has not "redefined" anything..

They are, in fact, defining what their Superlative Chronometer statement means.

COSC is still COSC and Rolex has never defined those as Rolex standards.

as of July 2015, everything with a green tag.

This had come up recently.

First off I don't know what's true and what's not, but what was discussed in that thread I'm thinking of was basically that since the launch of these new standards, which was essentially a year ago Basel World 2015 with the DD40, all COSC watches should be held to these standards.

Now where to draw this line on the timetable is the question. Again, this is just what I remember from that thread, but what was said by most is that the most basic way to know if your watch is supposed to be within these new specifications, is if you have a newer style green hangtag with your watch. The release of the green tag, 5 year warranty and new COSC parameters all coincide with each other.

Wait, I thought COSC meant that it was sent to a third party to do that, not internally.

There are no new COSC parameters. The COSC is completely separate from this. The new -2/+2 parameters are done by Rolex internally.

They have "redefined". They use that exact word on their website in regards to the topic.

The new Cosmograph Daytona carries the Superlative Chronometer certification redefined by Rolex in 2015, which ensures singular performance on the wrist.

Rolex is not COSC.... COSC is not Rolex.. Two different and separate entities..

All watches, including Rolex, will still have to pass the COSC standards at a COSC facility to be able to label their watch as a Chronometer.

Yes, Rolex still sends all the movements to COSC for certification. Once the certified movements return to the Rolex factory, and are mounted in cases, the resulting watch is then put through their internal, more stringent, Superlative Chronometer certification.

You are completely misreading this.

Rolex is "redefining" (actually defining for the first time, but it's marketing) what their statement "Superlative Chronometer" means, not what COSC means.

Agreed!

Also counting down to all the OCD people that will want their watch to run to the new spec and then panic over what to do when it does not

Attitude? None whatsoever here. Having a conversation about the topic.

Thanks Larry! And I realize that this statement is completely separate from from COSC certification. I guess what I was getting at was how far back (model wise) would they guarantee/warranty to -2/+2. Could be an influx of people running into RSC's because their 4 year old subs are not within this spec LOL!

[Memphis]

again.... read the comments dude.... POST #6

I don't believe that they have ever guaranteed/warrantied that the movement will run within any particular parameter, although many have insisted that they "must" run -4/+6.

However, that -4/+6 has always been the COSC parameters for pass/fail, a 10 second swing under torture.. Not really a swing anybody wants to see in their watch.

I would bet a donut though, any current warrantied watch will run to Rolex new standard (it used to be -1/+5 out the door) and they would likely time it to do so..

Oh excuse me. My mistake. Basically can replace everything regarding "COSC" and replace it with Rolexes own "Superlative Chronometer" Rolex certification within my statement and maybe you won't need to bang your head on the wall, figuratively (smiley) speaking.

Maybe not, that's ok too.

I think the "Superlative Chronometer Certification" is exclusively a Rolex terminology, and it is simply a marketing tool.
They have now decided to legitimise their marketing position with their in-house testing to a tighter tolerance of the cased up movements.
When Rolex refer to "redefined" it's because they used to previously use the COSC standard as a point of reference.
The reality is that Rolex never really had their own standards until now so the reference to "redefined" is slightly fuzzy.

COSC certification is separate and apart from this new in-house Rolex standard.
It applies to uncased movements sent by Rolex for "Chronometer Certification of Wristwatch movements to the independent body.
It is the product and an initiative of the Swiss watchmaking industry and their desire to have a standard for marketing purposes.

[Rookie52]

Bit more info:
COSC Certification: -4/+6 (10 second delta) - Again and as mentioned many times, COSC is not affiliated with Rolex. They are a 3rd party testing institute.

Pre-July 2015 Rolex Officially Certified Superlative Chronometer: -1/+5 (6 second delta)
Post-July 2015 Rolex Officially Certified Superlative Chronometer: -2/+2 (4 second delta)

So by redefined, Rolex is referring to the redefined parameters for what they qualify as Superlative Chronometer. Although all are splitting hairs, it's nice to see continued improvement and tolerances tightening.

Rolex are COSC certified, but Rolex has stricter internal standards and quality control testing.
