Just measured the accuracy of my BLNR over 27 hours using Toolwatch. Result +0.9 seconds. Preforming within the +/- 2 seconds.

That’s great but you need to do a accuracy check over a period of weeks as your wearing habits can vary a lot. Tempature will also have a slight affect.

I set my BLNR time on 9/1 and checked it today. 25 seconds slow during the month, with everyday wear. I bought the watch new in August.

Are the measurements being reported based on 24/7 wear? My DJ41 is -2s/day when worn 24/7 but is -0.3s/day if left face up over night (8-10 hours). Just wondering what some of you are doing. Thanks.

If you knew how many seconds there were in a century, you'd be even happier!

I celebrate the watch by measuring its accuracy now and then. Happens once a day, more or less. Wearing it 24/7. |

Mine is over 1 second but def less than 2. Is that cause for concern? Im not using any app just timing it with my iphone clock. My blnr is barely 2 months old

Cause for concern most certainly not for any mechanical watch to perform within a few seconds a day is a mechanical marvel. Remember there are 86400 seconds in a day so please dont get OCD with constant checking time syndrome.Now all these phone apps will give a indication running fast or slow, but none are 100% accurate like a proper quartz timing machine.

My BLNR was the least accurate of my collection, gaining about 8 seconds a day. It was never dropped, bopped or dinged. I even kept it on an extra week in. Y rotation to see if it settled. It didn’t.
My most accurate is my PAM 359, gained 5 seconds in three weeks.

I have owned 8 Rolex's in my life (currently only have one) and my BLNR is the most accurate Rolex I have owned to date. I have a 1-2 second error after a month if I wear the watch every day. Its also the only Rolex I have owned where the crown is perfectly centered at 12 o'clock position.

My BLNR is my most accurate Rolex watch with the error between 0 (almost perfect by daily wearing and put crown down 6 hours beside the bed during the sleep) to 1 spd (if not wearing and put on the winder) since I bought it in June 2014. The least accurate Rolex watch is DJ with the difference around +5 spd since I bought it in February 2014.

BLNR accuracy.
I went through a period where I would time my Sub every 12 hours with an app and what was interesting to me was how much the accuracy would swing back and forth during the course of the day and overnight, while giving me 0.5 sec/day or better over the course of a month.
Obviously a lot of the variation was due to my less then perfect reaction times when tapping the key on my iPhone to test the watch against the app, but it made me appreciate even more how complicated these little mechanical things are where a watchmaker needs to adjust for accuracy in a bunch of different positions to get a good average accuracy. This also strengthens my appreciation for the reliability of these Rolex movements (and, I know, other movements are good too)-- the fact that a mass produced, and very complicated, piece of micro machinery can still be accurate within 1/2 second per day after 14 years or so years of being produced is pretty mind-boggling to me. |

I bought my 114060end of April and have never reset it....currently +5. It runs slow on my wrist by -.5 to -1 and stays the same in most positions, but after a few months I learned it will run as much as .5 fast when crown down. So after being -20 after the first couple months I started resting it crown down while I slept and it eventually worked it’s way to +5.
Love that! Nice to be able to positionally regulate it, especially since it’s a non date watch. Will really only need to reset it twice a year for daylight saving (it’s my only watch so I wear it everyday) It’s really amazing how accurate these movements are. Used to think COSC was great, but +/-2 is really fantastic, especially for someone who’s ears the same watch everyday like I do. |

I know it’s not really representative of anything, but mine retuned this today (close to fully wound at the beginning of the measurement period). It was -1.2 with low powe reserve. Though I’ve been into watches for years, it always surprises me how good these little machines are.

The nightstand positioning trick works very well and allows you to really get to know your watch's performance. I usually swap out watches multiple times per week so never got the chance to experiment. Since I'm on a long trip with only 1 watch I've found that my 216570 with the 3187 will gain a little under 1 second overnight if I leave it on it's side with the crown facing up. When on it's side with the crown facing down it loses a little under 1 second overnight. Coming up on 6 weeks with no time changes its spot on.
One of the coolest things I've learned here on TRF! |

my brand new BLNR was 5 minutes slow per day.... had to send it in right after I got it for warranty work. Longest 3 weeks ever, but running flawlessly now!

BLNR accuracy.

Just a word of caution. I have been timing mine using that app and making a burst photo with a time stamp as the second hand was at 12 o’clock. The app itself wasn’t always precise as I saw in comparison. Unfortunately it doesn’t allow for charting the watch precision development over many days, so I can’t found that on actual data. With the photo method I have now many months of measurements so I can trust that one. |
