Regarding the 14060, it possible to . . .

. . . regulate a 5 digit sub to current -2/+2 COSC standards?

Thinking of buying a random serial number 14060 but I'd like to have it regulated to tighter specs than -4/+6.

I have my 4-digit Submariner regulated to +15-30s/month.

This is possible if you have very regular wearing patterns. If I rest it in a specific position during night I get the lower number. Note that you might have to go back a couple of times to your watch maker to make the final adjustments!

Lets get thing perfectly straight Rolex still testes the bare uncased movement to the COSC spec which is a AVERAGE of -4+6 seconds in any 24 hour period to get the COSC certification.And while testing in the first ten days of test the movement could deviate by up to 10 second on any single day and still pass the COSC test.After test movements are shipped back to Rolex in there hundreds Rolex has there own machine at COSC because of the vast amount of there movements tested. After being stored at Rolex HQ for weeks,, months or even a year they are match to a case.Then they are timed again on a machine in there case to this -2+2 spec which has nothing to do with the COSC.And just because its been regulated on a machine do not mean it will perform 100% exactly on the wrist every single day for life.

On the wrist there are just too many variables to 100% guarantee movement will perform to -2+2 every single day.On the wrist things like the movement is constantly affected by the earth's gravity, metal expansion and contraction,mainspring-power reserve, temperature variations, subtle changes in lubrication and friction,daily shocks on the wrist,wearing habits and so on.Remember this the escapement of a mechanical watch in 24 hours pushes the gears 432,000 times,since a day has 86,400 seconds.So for any mechanical watch to perform to within a few seconds a day is truly mechanical marvel, and I am sure that 2 seconds difference either way will have no impact on any persons life unless extremity OCD.

Below picture COSC test use the first column thats movement of Rolex size.

Yes it is possible to regulate it like that. The 3135 is super easy to regulate very precisely with the microstella.

Peter, your knowledge is astounding! However, it does impact my my pleasure owning a Rolex even though I'm not OCD. Your explanation seems to partially answer my question.

Once cased, if the movement doesn't meet the -2/+2 average it seems Rolex must regulate it so that it does. My question is can the 14060 movement be so regulated.

Actually, life is to short not to enjoy my watch the way I want to.

And it's not accurate timing that is important, rather an accurate Rolex that is important.

Yes, just a matter of taking the case back off, checking how it runs and then regulate it by turning the small screws on the balance wheel with the microstella tool.

Many movements today can be regulated on a machine to the -2+2 spec even Chinese made movements like the Seagull ST19 cost of movement just $60.But seeing the ST 19 is not a chronometer movement will need regulating more to keep it there.But take your cal 3000 in your 14060 if you have the later after 2000 it will be 14060M with the cal 3130.But again on a machine it could be regulated to average -2+2 but on the wrist in everyday use could differ slightly.

Rolex, in the past, never said that they regulated their watches to -4/+6, that is the criteria for a COSC test - not Rolexes out-the-door spec.

Their recent proclamation that "Superlative Chronometer" means -2/+2 came out without a real change to the movements at all. They are still tested at COSC to meet the -4/+6 chronometer spec., that has not changed.

They (hi-beat movements) have almost always been capable of better than COSC..

My non-COSC 14060M runs at less than 1 spd after service at Rolex Canada. It can be adjusted very precisely.
