Why is my Rolex running so fast?

[Galexy]

My 2001 36mm Rolex DJ 16234 is running consistently +7 seconds fast every single day. I wear the watch everyday and only taking it off at night. Have tried placing the watch down in every single , possible position overnight but still runs the same and no changes. Does not gain nor lose any time. The date changes about 5 minutes before midnight every night.
I purchased the watch pre-owned from a non-Rolex dealer on Jan. 19, 2020.
The watch was last serviced in Sept. 2019 from Swiss Crown USA and is still under warranty until 1/2023. (Paid $600 for warranty) Covers (3135) movement, case , crystal , bracelet, crown, bezel etc...
I love this watch and even though I bought it pre-owned it still looks bran , spankin new. The jubilee bracelet is in perfect condition with no stretch or marks.
Would love for this watch to run within COSC specs or +/- 2 seconds per day.

Should I take it to a Rolex dealer for service?
Or Take it back to Swiss Crown USA for FREE SERVICE?
Any suggestions would be much appreciated.
Thanks!
I’ve never heard of Swiss Crown USA.

Chances are that it just needs regulated not serviced. I’d return it back to where the service was done and have the regulate it and the re pressure test it.

Why? It only cost that much for a service! Why not just chance it? Also doesn't a service come with an implied warranty? As far as the timing possibility it is magnetized?

I would take the watch back to Swiss Crown USA under warranty and relay what you have just told us to them.

As Tim has already mentioned, it probably just needs additional regulation and a pressure check to ensure Water resistance after opening the caseback to do so.

Why not just chance what?

If my car mechanic warranties his work for 1 month and you pay $500 for the work, why pay an additional $500 for a 1 month warranty?

Maybe someone is chasing it?

The watch is still under warranty from the place that did the service. It shouldn’t cost him a cent to have it regulated by the same people. Nothing left to chance.

In re reading the AP’s post he does say that he paid $600.00 for the warranty, why not use it.

[joli160]

A simple regulation is all that's needed.
COSC specs are -4/+6, so it's really only 1 second off

[Dirt]

This is ridiculous.

Your second hand watch is a 2001 model and it's only required to run within COSC specs (+6 to -4).
So yours is 1 second faster than that but is by your account showing exceptional precision.
I respect a high level of accuracy as much as anyone but would be content with it until it's next service becomes due and ask them to pay special attention to the timekeeping.

If it's genuinely bugging you, then by all means take it back and ask if they could fine tune it to run closer to 0 if possible which should be achievable given it's outstanding precision.
If you do take it back make sure you are kind enough to praise their workmanship regarding the precision of the watch.

Sorry I probably am mistaken. I assume that the service center automatically gives a warranty with the service so paying $600 for a warranty seems wasteful.

+7 gain everyday is just a tad out of COSC specs and if it’s consistent +7 a day that’s only 49 sec a week.

I am curious when Rolex implemented the +/- 2 SPD, my DJII gains a solid 3.5 SPD regardless of resting position so by weeks end it’s 25 secs fast but still well within COSC specs but not there new spec of +/-2

[frank4242]

You should get a new one though

[HogwldFLTR]

IMHO it's just not worth getting it regulated and being without it while it's gone. +7 is really nothing to worry about. I had a watch running 11 secs and sent it off for regulation; it just wasn't worth it. You might try buying a demagnetizer to see if that helps.

[juve]

Just take the watch back to Swiss Crown.

To that I do agree, we both seem to be in the same church but different pews!

[Brian Page]

I would just leave it alone, not that bad at all.

[Harry49]

Run after it... hahaha

[Tools]

Have it regulated. If you are near where you have your warranty, they should do the job for free.

It does not need a "service" as we use this term to mean "overhaul".

Almost anybody who works on Rolex can regulate it for you, but that might void the warranty you have.

Don't worry about when the date changes, it's close enough.

Cut down on the caffeine.

[NachoNeal]

I know you said you tried regulating the watch by laying it in every position possible but perhaps you should focus on only laying it down in a vertical position with the wind button downward, which I believe is the suggested rolex position to lose time.

I have been wondering this myself. One reference I have found, https://www.ablogtowatch.com/rolex-e...n-house-tests/, suggests Basel World 2015 is where/when "the new Rolex Superlative Chronometer Certification” was introduced. This indicates an update from the previous Superlative Chronometer Certification.

My research has yet to find any other reference.

All well and good, but the OP describes the watch as being in excellent condition.
I wonder what the next post will be about after regulation and there's a scratch or gouge on it where there was none previously. There's potentially more risk for all parties going down this path and all for 1 second per day

All the OP has to do is set the watch behind by hacking it an acceptable amount every month(or less as required) to be behind the reference time and wait until it's advanced a similar amount. Repeat as required

There never was a previous Superlative Chronometer accuracy standard.
It was all just a Rolex marketing stunt.
Having said that, Rolex would always happily adjust a watch to run very close to 0 if one were to request it(at least this was my personal experience anywhere in the world). This i took to be representative of their commitment to service level quality standards and has endeared the brand to me for life.

Obviously this is a different situation where the OP is reliant upon and bound to a third party.
As I said above, it could get unecessarily messy.

That there was a "previous Superlative Chronometer" standard was suggested in the article referenced. I am merely the messenger.

[Andad]

See post 2.

[Galexy]

The warranty I purchased is good for 3 years.
Thanks! 😎👍

[Galexy]

Thanks for all the feedback! It really helps.
It doesn’t bug me enough to have to send it back for a check up. I’ll probably just get it regulated at some point as suggested.

[Galexy]

I actually just bought a DJ 41 Rhodium dial with a jubilee bracelet. That one seems to be running with -1 second per day. I have no issues with it so far.
Thanks for your recommendation!

I’ve never heard of Swiss Crown USA.

If it is only +7 seconds per day please do nothing for now. My Sub C is +2 or +3 seconds per day which is within specs, and I do not really care because I wear it max 1 day in a week or sometimes even less often:)

If you keep the watch for 2 more years, towards end of that 2 years warranty period you still can go to the RSC (not to AD) and get the issue fixed for free from warranty if it annoys you. No need to rush and take risks. Considering the experiences of people on forum with ADs services, you might have new problems which you did not have before.

Hi,
I tried that already but didn’t work at all. ( tried upward and downward )
Thanks!
