Calibre 3285 -8s a day

[arodriguezt]

Hello all,

Been wearing my 126710blro daily since I purchased it in February 2019. Recently noticed it losing around 8 seconds every 24 hours.

Is this normal? Should I take it to the AD?

It doesn't bother me at all, what can bother me its the fact the movement can be damaged/damaging itself and getting worse over time….

Thanks

[THC]

Enjoy that beauty and rest easy

Seconds a day are a ridiculous way to spend your valuable time

[padi56]

Your movement is not damaged but remember there are 86400 seconds in a day.Remember this the escapement of a mechanical watch in 24 hours pushes the gears 432,000 times. Many things could affect any watch on the wrist such as the earth's gravity, metal expansion and contraction,mainspring power-reserve,different temperature variations, subtle changes in lubrication and friction, shocks, and so on.The fact is that no mechanical watch made will keep perfect time, very close yes but perfect no.But if your watch gets a lot worse then its needs looking into by RSC.Although the bare uncased movements are still tested to a AVERAGE -4+6 seconds to have the name chronometer on the dial.And now Rolex further tests in a controlled environment to this precision -2+2 spec at time of testing,but on the wrist wearing could be different as as above many variables.

If it's not bothering you then just enjoy the watch.

It's out of spec but also out of warranty. I'd wait until it needs more serious scrutiny, whenever that might be.

OP, I'd adhere to this wisdom 100%... Is it technically out of spec? Yes. Are you within your WIS rights to be mildly annoyed? Yes. Does this warrant prematurely spending a few hundred dollars on a repair before it truly needs service? I don't think so.

[Easy E]

Well, it is out of spec and most certainly won’t get better on its own. If -8 doesn’t bother you, which is absolutely your own call, what is the number that will bother you?

[Kevin of Larchmont]

Oh boy, here we go….

[Gearjockey]

Would bother me greatly.

+4 to 8 SPD, not a problem.

->4 SPD and trending negative, time for me to evaluate.

But that’s just me.
Could be a long thread.

[Smobews]

Take it to AD and have them adjust it. If it gets worse you will need a service. They will also be able to tell you if it needs service because of low amplitude.

[Stan Cooper]

It would bother me enough to pay to have it serviced by the RSC. Bas' post HERE gives me hope that Rolex has finally fixed the 32XX problem.

[Strad]

My Deep Sea that I bought in November 2019 start losing time in May of 2023 and wouldn't autowind to keep it accurate. I had the AD send it in to the local RSC under warranty and it came back running within spec again.

If your watch is under warranty, I would send it in to get it running within spec.

[S.Explorer]

It's only just out of warranty. I'd take to the service centre and see what they say.

[Jackie Daytona]

My 3235 tested -8 on the timegrapher at the AD, but I noticed it was a few minutes behind after a couple of weeks (5ish). I took mine in because personally it bugged me as it had been spot on before.

While 8 seconds a day isn’t really bad, in my situation for a new(ish) under warranty watch and showing -8 on the timegrapher I opted for service as I believe my real life wearing and time keeping may have been worse as that -8 was only in one position.

If it doesn’t bug you no would say leave it. Just sort of sharing my logic in a similar situation.

[East of Eden]

It’s normal for a 32xx, lol

Beautiful reference

Normal? yes (see post #13)
Take it to AD? no, it doesn't bother you
Damaged? no
Getting worse over time? yes
Listen to the 86400 "experts"
Do NOT read the long 32xx data thread

[MRBolton]

It's crazy to me how many people think it's ridiculous to expect the watch to perform within -2/+2 seconds a day. Why would Rolex print "Superlative Chronometer" on the dial if they didn't mean that it should run within that?

The 3285 Rolex specification:
"Precision -2/+2 sec/day, after casing"
Think about it!

Exactly. People will still go, "Oh, you paid for the watch that is supposed to perform at -2/+2 seconds a day, and it's out of regulation by a factor of 4x? Don't worry about it!" It's perfectly reasonable to be bothered by performance not being as expected and advertised.

One can try to understand that the perfomance of mechanical watches, measured by Rolex with professional timegraphers, specific and detailed test protocols, and under very well controlled conditions, is NOT the same as the timekeeping on a wrist of an owner. Many parameters influence the accuracy of a mechanical watch, including wrist position, gravity, temperature, acceleration, regulation, power reserve … Especially temperature is not considered at all in discussions.

The well documented 32xx issues aren’t due to any of those factors, which I assume impact every other Rolex model that doesn’t have these issues

I agree that the watch will perform differently on the wrist. Each persons daily wear patter is different. The same watch will most likely perform different for me than you. I feel that the +/- 2 spd speaks more to its precision. It leaves Rolex in that range of accuracy, it can also be adjusted to that range of accuracy. If I wear the watch and it is running 4spd, I can have it adjusted at an AD for free to bring it into the +/- 2 spd range, and it will stay there consistently. (Unless my wear pattern drastically changes)

A watch can run at -10 minutes/day with a precision of +/- 2 seconds/day.

You said ‘perform’?

If the OP’s watch is -8 second/day every day then it can be adjusted for accuracy.

Suggest looking up the difference between precision and accuracy. A watch running between -8 and -4 seconds per day meets this test.

No it doesn't.

Perhaps not in watchmakers terms, but in mathematical terms precision means variability around a mean. In the case I used -8/-4 seconds per day would reflect a mean of -6 and indicate a precision of plus or minus 2. Quite different than accuracy where the reference point is not an average, but rather a fixed point as for example, an accurate clock. I’m not sure what Rolex means, perhaps accuracy not precision.

[vesnyder]

I would definitely have it checked as you are on the verge of your 5 year warranty expiring.

If it's only just out of warranty perhaps they might still cover it if you tell them that you're familiar with the issue discussed by many owners here: www.rolexforums.com/showthread.php?t=786299
