Time Tolerance +8/10secs

[Daytonaman799]

What tolerance should one have to get something serviced. My 118206 has started running 8/10 secs fast. It’s under warranty so I was wondering if this was fast enough to warrant getting it fixed or not. Most of my Rolexes keep amazing time and this watch did for much of the last year. It’s something I noticed. If it was one of my PP’s I would tolerate it more but I tend ti expect for from Rolex. Is this OCD or should I get it fixed? Thx much in advance.

I sent mine in for warranty service when mine suddenly jumped to 6 secs/day fast. I think they are warrantied for being no more than +- 4 sec/day. The AD serviced it and came back +1 sec/day all under warranty.

For some reason, even if it's within spec, anything more than 3 seconds a day drives me crazy. 3 seconds fine, 4 seconds looking at service

Well seeing there are 86400 seconds in a day even if 4 seconds out either way cannot see what difference that would make to anyone's life today.

[Eagles4133]

has it ever been serviced? My explorer I ran consistently 2-3 seconds a day for years then around 6 years it jumped to about 7. It was due for a service so I sent it in, now runs about +4 per day.

seconds per day gain/loss really only bothers me when I have 2-3 watches in a rotation and they are all a couple seconds off. Not sure who to beleive!

Your watch can do much better than that.

If you don't mind it being gone for a while, have it regulated under warranty.

[shedlock2000]

I have just received my 116710 back from RSC for a similar issue (-9spd). It was just outside of the two year window, and RSC resolved the accuracy issue and returned the watch in 9 days (RSC 700 — Toronto, I believe). It’s currently running +0.3spd.

Sincerely curious..

Why would you have more tolerance for an under performing Patek compared to a Rolex? It's (unfortunately) a brand I can't afford, but considering the cost of admission, it seems counterintuitive to have lower performance expectations for a product generally considered more premium.

[DJ2020]

Accuracy does not go hand in hand with price or luxury standing. Nor does durability. For example, the finest Rolex mechanical watch pales severely against a GS9F in every possible subject except resale, which I could care less about.
Grand Seiko 9F on a bad year is more durable, just as Anti-magnetic, 10 seconds a year, extremely shock resistant and a 50 year run between services. All the while maintaining that 10 seconds a year Accuracy. For a poultry $3000 brand new.

Many Rolex's never make it to the end of warranty before a intervention is needed much less the suggested 10 year mark. I'm talking 32xx's here.

As far as full mechanical movements are concerned, I will trust a Omega 8800 or 8900 movement to hold up much better than any new Rolex. They are outstanding. But so are alot of other movements. Precision over Prestige I always say. Get a movement with the lowest delta, Anti-magnetic and materials that are not concerned with temperature variations and adjusted to 6 positions in the case you will have a watch that will provide you with years/decades of accurate service.

Hype or paying more won't guarantee you durability or Accuracy. People make the assumption that paying more some how equates to Accuracy, It does not.

[Calatrava r]

I think some watch companies make a mistake touting such tight tolerances, a second or two a day, on mechanical watches. Most of the high-end brands do not do this. If such accuracy is needed, resort to a cell phone is the best option.
Timekeeping only bothers me if I have to reset the watch more than a minute weekly. That is about my rotation anyway.

But since your timekeeping is out of range and is a new development, I would have it looked at as it may only get worse.

My experience is that they are more delicate and temperamental. My 5726 keeps time dead on but my 5712 has always run a bit off even after service. My old 3700’s were just very inconsistent. My Rolexes have always been dead on.

+10/day was within chronometer specs till the 1970s.

The OP states that it makes a difference to them. So saying that it shouldn’t make a difference, helps in what way?

I don’t have your experience, but I thought Rolex’s COSC rating was +4-6 on everything from the 1675 up? That’s 10seconds, but not +10spd.

On the one hand, in the grand scheme of things, sure, 8 or 10 seconds isn't the end of the world. But when the thing is marketed for 2 seconds--and presuming you've jiggered your routine, if applicable, for best results--I certainly understand the dissatisfaction. My DJ started in the +2 neighborhood, but when it gradually slid to a -5 even with best night resting procedures, sorry, it was RSC time. I'm glad I had mine adjusted.

While competitive chronometer testing took place at the observatories in Neuchâtel (1866–1975) and Geneva (1873–1967), testing of large numbers of watches intended for public sale was conducted by the independent Bureaux officiels de contrôle de la marche des montres (B.O.s) established between 1877 and 1956. Between 1961 and 1973,[22] “a chronometer [was] a precision watch, which [was] regulated in several positions and at different temperatures and which had received a certificate [from the (“B.O.)]." Collective certificates, rather than individual certificates, were usually issued. The 1961–73 standard required a mean daily rate in five positions of −1/+10. In 1973, the B.O.’s came under the C.O.S.C. which specified a daily rate of −4/+6 sec.

Only one question comes to mind in this instance.
Has the watch been knocked or bumped up against something, or even dropped?
If so and there's some visible damage to it then it may need a service

In some circles a Patek is regarded as more premium than a Rolex, but that's applying a totally different set of metrics altogether
A Rolex is better in some respects and a Patek is better in other respects, it's just the priorities are very different but in some quarters they are equal.
It's a balance between perceptions and practical realities

Fact before the Swiss COSC was formed as it is now it, there were Observatory testing and competitions to a much higher standard than the now antiquated Swiss COSC test.And during the entire 23 years of testing, 5093 wristwatches were submitted for certification, and only 3253 were passed, about 64%.And in those days just a few manufacturers participated, and only Omega and Patek did so every year. The others were: Rolex, Zenith, Longines, Movado, Vacheron & Constantin, Ulysse Nardin, Cyma and Favre-Leuba, along with numerous independent professional watchmakers.That was until Seiko come on the scene and started to wipe the floor with the Swiss mechanical watch industry.Only 2 brands in the + 23 years of the competitions submitted movements of serial production for normal retail sale(Seiko and GP).All others were specially made one off movements just for the competition.And it was ended by the swiss in the early 1970s after two straight wins by the Japanese straight off the production line Seiko Grand watches.


Seiko first entered the competition,with watches from all over the world,including most of the Swiss high end brands.For a much higher standard than the COSC,the Astronomical Observatory Authorisation Chronometer Standard.Out of many watches summited only two passed this test a Seiko Grand just a production model, and Giraud Peregaux a specially build for the test model.And in the late 1960s there were only two companies, who could sell watches, passed astronomical observatory authorisation Chronometer in those days. ---Seiko and Giraud Peregaux.As the Japanese had dominated in the very late 1960s and the two preceding events, in 1972 some Swiss watch manufacturers demanded the end of the observatory competitions,and it was ended in 1973,thats when the watered down COSC test was founded.Its most important to remember that a "COSC certified chronometer" is not the Holy Grail of watchmaking. With the high quality of modern day robotised manufacturing, this test is not that important in reality. As today most decent modern watches from all countries even some from China like the Seagull movements, when adequately adjusted, should be able to match the performance specified by the now quite antiquated Swiss COSC test even the newer Rolex introduced -2+2 spec.

A chronometer certificate is not a guarantee of future accuracy for life only a certification that the bare uncased movement was tested at the COSC and passed the AVERAGE -4+6 second spec at time of testing same for the new Rolex machine precision -2+2 test. Watch movements that have been certified can get out of adjustment and still perform quite poorly outside the COSC spec or the -2+2 spec.

[Harry-57]

It's out of Roles spec. The difference bothers you. It's in warranty. A no brainer for me. Your choice. What if it gets worse after the warranty has run out?

[ExplorerGMT]

8-10 seconds is unacceptable. At the end of a month you will be five minutes too fast which in my option is no better than a sundial at night. I would get in in spec based on the model.

[brandrea]

It wouldn’t bother me and I’d wait till next service.

I understand it might be an issue for others. Send in for service if it does

Have to agree take the Chinese Seagull ST 19 movement normally out of the box can run a consistent +4 to +10 seconds a day.But after careful regulation can match COSC spec even the new Rolex -2+2 precision test cost of movement around £60.

[robinmgb]

When I upgraded from Rolex to higher end brands including PP, VC, AP, Breiget and Blancpain I wasn’t expecting accuracy near the Rolex level but have actually found the opposite.
Most Rolex I’ve had are in the plus 4/5 seconds a day while the higher end watches have generally been spot on to plus 3 seconds!

[Snowballs]

Service time IMHO

[Daytonaman799]

Am going to see if it’s a 7 per day or not. If it is then I am going to take it in.

[Catatafish]

Within the warranty period I typically just take it to the local AD to have a look. The two times I've done that (once for Rolex, once for Seiko) the local shop regulated it and gave it back to me a couple of days later. The Seiko wouldn't stay regulated so I sold it. The Rolex has been under +1 a day ever since (3 years later still running strong).

If you lose your job because you are obsessing about your watch then it’s OCD. Otherwise it’s just mild understandable concern. You’re welcome.

[Harry-57]

My 2018 black SS Sky Dweller was taken off, adjusted for correct time, put on a winder and left in a safe on 01/03/2023. I took it out to wear today. It could have been a couple of minutes out in either direction. I would have settled for five minutes. It is showing the correct date and time and it hasn't lost or gained a second since I last wore it.
