What happens to a Rolex that fail internal accuracy test?

[amphr1]

So we know they test them to within 2 seconds. If they made a watch and it's 3 seconds off, do they just get regulated and try again until it's good? I don't suppose you just trash the whole watch. So it's really about regulation rather than some inherent advantage in production quality right? And so if it goes through RSC, do they go through the same test again?

They adjust it again.

They don’t fail

[fskywalker]

Think would keep at it until it pass, if not replace parts until it does

They ship it and assume it will be a warranty issue so production quotas are met. Rolex makes them. Rolex USA and the importers sell them. RSC fixes them.

(Don’t @ me you know this is the truth!!!!!!!!)

[WatchGuy1966]

Probably you are both correct to an extent

Or, almost none fail (the testing. A few per thousand will

And most of the ones that do fail are probably shipped if they fail within a reasonable threshold.

The few that fail miserably are sent back to their maker.

Maybe - I'm just guessing.

They adjust the regulation until it passes. They are adjustable. If it can’t meet goal, they replace parts until it can.

They label it a 32xx movement and sell it.

[alphadweller]

Those watches with subpar movements go direct to grey dealers.

No, it's both. Production quality and strict QC are what give consistent product/results.

Stole my response!

They don't test them to 2 seconds, they are still tested by COSC using the same criteria used for the past 40+ years. This allows them to put Chronometer on the dial.

After back from COSC, and they have a case/model assigned to a movement, they go through the movement again and finally regulate it to +/- 2 seconds.

I can twiddle with my Timex and get it to 0.0 s/d on my timegrapher in one position. Most any watch can be regulated within +/-2 s/d...in a single undisturbed position and a full wind. But flip it over or check it again in 6 hours and it will show a completely different result. It has zero chance of ever being COSC. It wasn't designed to. The measure of a quality movement is the ability to hold accuracy throughout a length of time in multiple positions and levels of activity. It doesn't take much time playing around with a Rolex and a cheaper watch on a timegrapher to see how one is affected much less by position than the other.

Got to say my 3 Rolex watches keep fantastic time better per week than my other watches per day

[CedCraig]

Very early in Hans Wilsdorf‘s watch salesman career he noticed that some of the watches he was selling ran better than others, so he would buy those more accurate watches from the shop and resell them for a higher price. So the importance of quality regulation was part of Rolex from the very beginning.

Well said.

[StanGMT]

The concept of timepiece accuracy is often misunderstood. The COSC chronometer certification is about the movement's timekeeping consistency. A movement can run fast or slow, but as long as it gains or loses at a very consistent rate in a range of conditions it can be regulated to keep right time. So, just because a movement runs fast or slow doesn't mean that there is necessarily anything wrong, or that servicing is required - if it is consistent, then regulation might be all that is needed.

[amphr1]

So if my watch is consistently slow by 3 seconds, can I bring it back to a RSC and ask them to regulate it so that it's consistently +/- 2 under warranty?

Purchased an Explorer 39mm 214270 MK II dial fresh from the AD back in 2020. Watch was minus 10-15 seconds per day. No idea how it managed to slip through the quality control. Nonetheless I took it back to an AD in my area and they were able to regulate the movement under warranty. It ran minus 0,5 seconds per day after I got it back.

I think they just ignore something close out of spec. 99% buyers could careless or they don't even know.

Certainly seems to be the case.
