From Paragraph 5 & 6 of the 6th issue of Rolex Magazine in the article discussing the Superlative Chronometer Certification.

"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 is of the order of -2/+2 seconds per day, or more than twice that required of an official chronometer. This precision is tested by Rolex using an exclusive methodology that simulates the conditions in which a watch is actually worn and is much more representative of real-life experience."

I don't think I'm wrong in saying that they do guarantee that performance, every day on the wrist.

I think that you should re-read what you cited. They guarantee "superlative performance", not a specific absolute; the precision of a Rolex is "of the order of....."

While I am sure that they will strive to please, there is definitely wiggle room.

What would be considered acceptable performance that is "of the order of" -2/+2, as I expect we are defining the phrase "of the order of" to mean "approximately"?

is -4/+4 approximately the the precision of a superlative chronometer? That's 100% outside the specification range. Or would a whole order of magnitude still mean approximately, -20/+20?

I purchased my 14060M in 2010 and have checked/recorded the accuracy daily since. (I am retired and have plenty of time to amuse myself with this sort of nonsense)
Initially it gained an average of 8 secs a day which gradually increased to 15 secs over 3 years when I sent it to the RSC for a full service in late 2013.
On return it averaged 2.1 & 1.65 for 2014 and 2015 but in 2016 it went back to the RSC to have Pallet Forks replaced and since then has averaged 4.6 secs.

My 16233 DJ, by comparison, which is treated exactly the same as the 14060, was consistently accurate (+2 sec) until it went to the RSC in 2013 for a failed Crown, and was consistently +7 secs thereafter until sent back to be re-adjusted.
Since then it has been consistently 2.5 secs/day.

I concluded from this that :
(a) Some watches are just more accurate than others, right out of the factory.
(b) Some watches are just more consistent in their timekeeping than others.
(c) Sometimes the RSC does a better job of adjustment than at other times.

With all these RSC stories out of the US, I feel very fortunate to be able to have my AD send my watches in to the factory here in Switzerland when I need to. Service seems to be very different around the world.
