Will RSC tune older watches to +2/-2 when serviced?

[bjw]

For example, I have a 2013 GMT BLNR in for a new crystal replacement at Dallas RSC and since it was running anywhere from +4 to +7.5sec/day, I am having them re calibrate back to COSC. Now, since its the same make/model as the GMT from when they started guaranteeing +2/-2. Should I expect it to some back +2/-2 day? It the same watch. I assume with the same parts, oils, etc. I assume the process is the same for calibrating a watch would be the same weather it's a 2013 or a 2015 (or when ever started the +2/-2).

Or is there a difference in the newer watches that are being guaranteed +2/-2 of which i'm not aware?

Last time I was in RSC Hong Kong I asked that very question, their answer was they can regulate to +2/-2 a day if it is the newer movements. For all older movements they are aiming for COSC.

Don't know how "official" that is but that's the answer I got.

Hmm, does it matter? I'd say that's definitely up to the owner of the particular watch and how it's performing.

I for one am very happy with the +2/-2 spec/performance. I don't have to adjust my 214270 & 216570 at all in a month and they're accurate within the minute.

But hey, the guy asked a question and I gave the info as I received it. To regulate or not is really up to him.

And thank you for answering my question.

And it was a question out of curiosity. Will I send the watch back if it's not +2/-2 out of the gate? No, of course not. Would I have sent the watch in for only calibration? Again, no.

It was simple a question I had and thought others have might wondered the same.

It was a good question and worth asking IMO

Let's get things perfectly straight most all the 3 series movements first introduced in 1988 till present time have changed very little.Sure now most have the in-house made escapement parts but no big deal there.The bare un-cased movements are still tested at the COSC to the AVERAGE -4+6 second spec to get the COSC certification.After movements are shipped back to Rolex stored till matches to a case.Rolex then further regulates on a machine to this new AVERAGE -2+2 spec,what does this mean.Well at time of testing on the machine movement met that spec.This dont mean it will run for life at -2+2 every single day, just like all mechanical movements they will need some regulation throughout their life .But truth be told all the Rolex movements since the 15 series when regulated correctly could match this -2+2 spec.But does 2 or 3 seconds really matter out of 86400 in a day.

I just had a Rolex serviced in NY and they sent it back running at a +2/-2 per day. It went in running +6 per day. I included a request on the paper work to calibrate it to +3-4. They did not honor my request. But if you send it back for a time calibration you are looking at a turn around time of 3 or 4 weeks. They are running extremely slow and behind in NY.

[mui.richard]

3-4 weeks? Sounds about right. RSC HK quotes that turnaround time everytime I take my watches in for service.

In the end, regardless of how accurately the watch comes through RSC regulation >>>> YMMV. In fact, I'll even go out on a limb and say it will vary.

[RPB]

I'm talking London RSC however my GMT IIc is currently at +1.3 sec per day over 7.5 days so far using Watch Tracker app. I'm pretty sure it was only running around +3 anyway before. lol. I'll be obsessed for a month then I'll forget about it.

[GreenLantern]

Do you call in and give them a heads up before sending your watch to the RSC? Or do you just send it in with contact info included so they follow-up with you upon receipt?

[RichardF]

Calling in advance will not really speed anything up. They have one section that handles warranty repairs and returns. It just depends on their work load at the time and the nature of your watch issue. If it requires to be serviced again you still are looking at 4 -6 weeks. You can download the service form from the Rolex web site.

[watchwatcher]

I would think so...especially a newer watch like the BLNR. That should be low hanging fruit, IMO.

If I wanted 100% accuracy, I would be wearing quartz.

Exactly. I just don't care enough to get worked up over a few seconds here and there.

That being said, to each his own. I hope the watch comes back regulated to your satisfaction OP. Then forget all that and enjoy it!! :)

As mentioned many times around this forum, -2 +2 is still only an average over a period of time. My newly serviced GMT IIc is currently running an average of +1.4s, however that is based on 38 data points over (currently) 11.6 days so far using Watch Tracker app.
BUT, my point is that my watch is still only within the -4 +6 on a day by day basis.
Some of the data points are as high as +3.8s in 12 hours, and as low as -0.6s in a 12 hours period.

Jees, we need to stop looking and keep enjoying! PMSL. ;)

Take my advice ditch your watch tracker as its taking the pleasure away from owning and wearing a Rolex watch.Most all of these phone apps are more of a novelty than anything,and only as good as the microphone on your phone. They show the daily rate only, and most are not 100% accurate at all. The only true test is on a timegrapher this will read amplitude, beat error, and other things that must be corrected for a accurate result.Now many of these apps often lead to {OAD} obsessive accuracy disorder and then to the many other OCD Rolex owners problems.

Great advice for all. Lose the OCD accuracy thing and just enjoy the watch!

Is it also undergoing a service? Or only a crystal replacement and regulation?

If full service, I'd expect the new standard +2/-2 would be the target.

Agree with your position of saying you wouldn't send it back if it wasn't at the +2/-2 (I probably wouldn't notice to be honest), but I do think its a reasonable question, and I'm curious to know the answer. May be worth calling them up and asking.

[RPB]

Agreed with all the above :)
One I do is enjoy this watch. Apart from when I had a brief spell with a TT Daytona, I never took it off apart from sleep and showering. Lol.
