How accurate is your Rolex?
My 1981 DJ is running about 8 seconds fast a day. Not far from COSC spec but I'm going to see if an AD can help me out (maybe get it regulated, check for magnetization etc...).
I calibrate it with my cheapo Casio digital! So how accurate is your Rolex and how often do you set it? |

I have a new Daytona 116520 purchased in July this year and I find it is pretty darn accurate and reliable so far. I did measure it against my computer's time over a two days and I am sure there was a difference, but it was imperceptible to my eyes. No either tests beyond that. As well, the power reserve seems to last an extra couple days past when my Zenith El Primero runs out. I look forward for adding another Rolex or two over the next couple years. Wife is next though!

It's hard to believe how accurate my 1970 1680 Sub is! I'm talking within a few seconds a week, at most. As far as I know, it has never been serviced either - no marks in case, appears unpolished. Taken it to 2 Rolex ADs, who both tested it here in Zurich and confirmed she was running sweetly. Opened her up and looked at movement, too, which was pristine. They said no need to service.
My 1966 1675 GMT is also amazing, but was serviced by RSC UK about a year and a half ago. I set them to online clock on my PC, which is exactly the same as other online sources, to the second. |

My now 13-month old Datejust runs consistently 0.7 sec per day fast, or about 20 seconds per month.
I find this remarkable. Way more accurate than I expect or require, but it helps form a nice bond that speaks to Rolex quality. |

My Daytona runs +1.1 sec per day and my DJ runs about +1.5 sec per day.
Amazing accuracy! |

Hi,
My Datejust 116233 (my first Rolex) ran at about +4 to +5 a day, usually (so about 30 seconds a week most weeks, give or take). My Oysterquartz Day-Date ran at -2.5 per month, so was well within the OQ's 60 seconds per year tolerance. My current OQ Datejust seems to be running at about +1 per day, which is very badly out of spec for an Oysterquartz, but in real terms is good enough for me to wait to get it properly regulated the next time its battery needs changed. Lastly, it's very hard to say what my Cellini runs at (since of course it lacks a second hand), but very roughly I'd say it also gains about a half a minute a week (so is roughly comparable with my first Oyster Perpetual Datejust). |

My Submariner runs -2 to -3 seconds every 24 hours. I use my shortwave radio to check how accurate my watch is.

1 year old ceramic sub, at most, +1 to +1.5 sec day, and usually much less that that. Easy to adjust to zero by positioning the watch overnight. Rarely have to pull out the stem.

My freshly serviced 2002 GMT II is running about 3 seconds fast, but is still settling in I guess. It was running about +7 before the service.
My brand new DJ is running dead on at +/- 0 seconds! Very pleased. Wonder if the parachrome hair-spring has anything to do with it. |

my day date runs .6 seconds fast a day, which has me setting it about once a month. I'm happy with it and its fun to know the variance. I've found setting it dial up at night gets this result or it'll be about 2 seconds fast in any other position

Perfect
I am still amazed that after 16 days, my Explorer II is still perfectly on time.
I set it up the day I bought it using the Emerald Time app which calculates the time using the Network Time Protocol, and double checked it with the time . gov website. Here's a picture comparing the time of my Exp II (which I haven't adjusted since I bought it) and the NTP time... The total error in 16 days is about 1/10th of a second. Priceless! |

I have been checking my watch for just over a week now.
For the first 7 days it was 4 seconds out in total so .57 seconds per day average. I am now into my second week and after 2 days it is about 1 second off so it seems to be fairly consistent at about .5 seconds per day or thereabouts. It's fun to check and know but I wouldn't care too much if it were more than this. I have only been checking for 9 days now so I don't know if that is long enough to get a good picture. |

I do not worry about how accurate my Rolex is because I got reminded by my older brother that we have the body chemistry which stops mechanical watches. For this reason he uses his cell phone to tell the time and I prefer my Rolex.....as it is an automatic, mechanical watch and will not stop on my wrist but does not keep 'Great Time'. When I first owned my Rolex and for the first almost 5 years it was frustrating that it would not keep good/excellent time.....but Padi, reminded us all that even if the watch is off by a few seconds a day(even if outside of COSC Standards) it is still over 99% accurate which is phenominal for a mechanical watch. And as he has mentioned every time this topic comes up that if you want accuracy...get a quartz watch.....or for people such as myself...a cell phone!!!
Take it easy.....Leo
