Your accuracy expectations.
In a recent thread discussing accuracy, I mentioned that I have a SuC that gains less than 0.2 seconds per day, and a DSSD that will lose about 1.5 seconds per day. I mentioned that I was pleased with this level of precision. Another member stated that I should not be pleased. I know that Rolex has a standard of +/- 2 seconds per day. I was wondering what degree of precision other owners found personally acceptable. Thanks for your opinions.

+\- 15 seconds would prompt a problem and service imo.

With a new watch Id expect -2/+2 or its not meeting an advertised specification for the product. Older I'd say COSC for 5 year old watches and then its probably service time anyway to bring it back into spec.

Gravity affects mechanical watches the most thats why they are tested in 5 different positions.And in those different positions there will be very slight deviations in the timekeeping.Remember this the escapement of a mechanical watch in 24 hours pushes the gears 432,000 times.On the wrist the movement is constantly affected by the earth's gravity, metal expansion and contraction, temperature variations, subtle changes in lubrication and friction,mainspring power-reserve, shocks, and so on.The fact is that no mechanical watch made will keep perfect time, very close yes but perfect no and remember there are 86400 seconds in a day so will 2 seconds difference really matter only for the marketing.Rolex put this new spec mainly because Omega advertised it first, marketing or sometimes brain washing is a marvelous tool .Myself check my wearing watch about once a month even then its seldom out by a minute.

I have never taken the time to check for COSC on mine. I wind it every month or so and if it's a cpl minutes off here and there I move the hands accordingly..... Not a big deal.

The -2/+2 seconds window per 24 hours leaves me impressed every time I think about it. I can seriously not wish for more consistent time keeping in a mechanical watch.

To each their own. I grew up in the COSC era of -4/+6 and would probably not worry much if my watch was keeping that kind of time. But, with the -2/+2 committment, it is much more satisfying for one's OCD nature to see your Rolex chugging along in that range.
This said, the accuracy performance committment is an average. Checking every day will drive you nuts. I see where I am every couple of weeks and adjust no more often that that......since I am currently -1.4 to -1.6 per day, I have been adjusting about once per month. |

The parachrom is just a hairspring and nothing more, it was first introduced in 2000 with introduction of the cal 4130 in the Daytona.But then is was a grey colour now its blue by a chemical process, and the parachom was in many Rolex watches before this new marketing -2+2 spec.

Personally I think it's utterly extraordinary that my new OP39 is within a second a day, and has been since I got it 6 or 7 weeks ago. None of my three old subs (1680, 5513 and 16610) can do that. |

Minus anything or plus more than 4-5 sec/day would mean regulation/service imo...

Explorer II is 8 seconds in 3 weeks and two days. Althought i wear it in different altitudes a lot so it might decelerate and accelerate movement.

I just don't have the interest to do more than set my time with the Watchville app...and go. If my watch is off by a few minutes or 5 - usually because I mis-set it...I may notice. How do you get to the level of knowing you are a 1/2 second off? |

My current Rolex rotation of 2 watches are running at +1, very accurate.

I listen to BBC Radio 4 quite a lot, and nearly every hour, on the hour, there's a time signal.

It's probably a lot a combination of lots of things (hairspring, materials, lubricants) but they are tried and true movements and if you put in the effort to regulate them accurately it can be done. Didn't the Hodinkee article where they toured rolex mention that they have a camera that takes 2 pictures of the dial 24 hours apart and if they don't exactly match they re-regulate?

I don't think that can possibly be true, can it? Could you post a link to your source on this one?

This! I personally don't care. I'm happy with some of my vintage that are off a few minutes per day. I just enjoy wearing and looking at them. Sent from my iPhone using Tapatalk |

It all depends on the watch. I don't expect even COSC from my 5513 and 1680, and am pleasantly surprised when they manage it. I do expect a lot more precision from PP, FPJ and contemporary Rolex because these brands market themselves, at least partially, on their accuracy.

I mean, why stress over it. Let alone incur the inconvenience and expense of sending the watch for regulation. Eventually it will likely fall out of your desired accuracy range, and you send for regulation again. Even if you did a random sampling of members at a specific moment in time who were OCD about accuracy, I would be willing to bet while all would likely respond with the same "minute" i.e., 10:31, odds are the second hand reporting would be all over the place. So, to that point, only when my watches (and each runs fast to a varying degree) are off by a couple of minutes will I then re-set, but in no way do I have the need, desire or inclination to track daily for seconds. I bought my watches for the enjoyment I get out of wearing them, and no to turn them into a daily chore to track accuracy. |

It's not a chore if you listen to the radio news on the hour. It's quite fun to see how various watches perform, actually. I don't bother resetting because I'll usually switch to another watch before any of them are >30 sec off.

Well after 5 days it was 1 second fast, after 10 days it was 2 seconds fast. after 30 days it is now 6 seconds fast. So on average I know it is gaining about 0.2 seconds per day. I compare it to the time on the GPS in my plane. Similarly, My DSSD will lose about 1.5 seconds per day. This precision level seemed more than adequate to me, but another member questioned my satisfaction with the performance of my watches. being a noob, I wanted to determine if most were OK with COSC qualifying precision / Rolex guidelines or other. From what I see here, I feel I am still pleased with the precision of my watches. Thanks guys!

I would not be happy with any of my watches running more than (-2/+2). They are currently running +1 to +2 per day. This is good enough for me, but I wouldn't take them in unless they got to +4-6. That would be fine for a watch that is worn occasionally, but not a daily one. It would drive me crazy if within 3 days one of my watches was 15 seconds ahead or something like that.
