Rolex is -1/+5 sec per day (-1/+3 sec per day with parachrom hairspring in 5 professional and milgauss) or so they claim....

Sorry friend but this is total baloney. Show me where they claim different rates for the parachrom spring models please.

You need to learn more about COSC and how Rolex fits in. Your assertion is one I have never heard before. There is no "Superlative" COSC rating, it a BS Rolex term only (see below). COSC is COSC and a Rolex, Panerai / Breitling, etc either pass or fail the spec. The only variations are for small movements (under 20mm) and, of course, the quartz spec.


COSC is like a Consumer Reports endorsement, basically bogus. COSC is basically "owned" by Rolex as they are the major customer by far. Rolex watches are no more accurate than others like PP, AP, Lange and VC that couldn't be bothered wasting time with a COSC endorsement, they hold themselves to a higher standard.

From Chroncentric:
How is a "Superlative Chronometer" different from a "Certified Chronometer" or just "Chronometer?"
The term "Superlative Chronometer" is a trademark of Rolex. 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. All watches that have earned the privilege of bearing the official Swiss designation of "Chronometer" have been held to and met the exact same C.O.S.C. standards. Any words added before or after the official designation of "Chronometer" are merely fluff--there are not any different grades or levels of chronometer certification.

Likewise, "Certified Chronometer" also means nothing different than just "Chronometer." It is a redundant phrase--since Chronometer status is a certification--that is used like "verde green" or "hot water heater" to ensure that the reader clearly and quickly understands the point.



Read up of COSC, it's a joke.
