How accurate is your Rolex?

[cdy266]

My SD4000 is less than 0.1 sec/day over 3 months! I wear it 24/7. Hard to believe but I have kept track for several long runs. :-)

[nursejm]

-.21 secs a day.. everyday wearing. At night stored with dial face up.


Best regards,

I wear a Rolex 5513, so even if I'm late....... I'm on time,

I never use the mechanical watch on my left wrist for real time. I consider it a close approximation of time to keep me somewhat on schedule.

The real time keeper is on my right wrist. An Apple Watch.

2012 SubC: about +1 s/day

[ivanos]

Less than 1 sec variance per month.

Have to agree last time I checked my 5513 was April 1980 just checked today its gained 1 hundredth of a millisecond in 37 years of continual running guys beat that one.Treble checked with my 3 phone apps, plus two radio controlled clocks and two atomic clock computer apps for conformation to a thousandth of a second .But in the real world I check once a month or so, even then my wearing watch is seldom less than a minute out.

+6.8 seconds after 2 weeks.

I got my GMT BLNR 5 weeks ago. I set the time exactly when I go to home from the AD and it's now 2 seconds slow. I'm happy with that..

Brought a brand new SubC running -2.5s per day. Wore it for three months, send it in to RSC Singapore for a regulation and came back +1s per day. Lay it crown up at night and now I'm at +0.5s daily.

Datejust with 3135 movement.

I use it every 6 months or so. Lift angle seems to be correct for these two movements. Dd a bit low amp yes, but I usually for 7 years before service if running on time, only 3 years since service on that watch.

My 14060M is averaging +.02 sec per day, no complaints here!

I used an app that was from the iTunes App store called Toolwatch. Its nothing amazing and does what I need it to do.

Hi all

Acquired a SubC around 3 weeks ago and so far it is around 3 seconds slow

That has knocked me out in terms of accuracy!

I store it crown down every night and have not let it wind down yet....

What a piece of engineering!

I have owed my explorer with 3132 movement since 2011 and the daily consistency after 6 years is 0.3 seonds variation a day. It is regulated to run 3.3 seconds fast but the consistency with how much is varies from this regulation is 0.2 seonds per day for the last month since I started checking the daily variation from how it is regulated. That is truly mind blowing isochrous time keeping.

Had i got it regulated to -+ 0 seconds a day then it would vary by only 0.2 seconds from this regulation on a daily basis.

This shows how well the changes have improved accuracy since this moments inception Abd the advancement in lubrication that ensure lower friction and a more consistent time keeping.

This could easily Achieve -+ 2 seonds a day since it is 10x the accuracy of the higher level COSC specification.

I don’t know how any watch can improve on a daily variation of 0.2 seconds per day for a months period.

I daily checked my accuracy and on the first day it was running 3.4 seonds and its never been more then 3.5 or less then 3.2 seonds.

The real accuracy of a watch is the consistency of the daily variation. And this movement people for me at least is showing unreal isochroism.

This is my daily wearer since I am a plumber and it gets treated real rough.

Remarkably accurate. I can get the time whenever I look at it.

My 116713LN does about +0.5-1 second per day.

[daveo5]

My Sub COSC non-date from around 2006 is consistent at + 1 sec per 24 hrs. Never been serviced.

[SveinEA51]

My 1984 GMT ll 16760 is fast by ⅔ of a second per day. I think that is amazing!

[drtii]

My 126660 is 1/2 second slow after about 5 weeks. I use the atomic clock online. When I first got the watch on 3/31/19 it was running about +1 second per day. I would sync it up to atomic just for fun every few days where it would be about 2 - 3 seconds fast.

After about a month of doing that I noticed that I was almost exactly in sync with the atomic clock every day, and now, I just looked at it's 1/2 a second slow for that entire span.

I'm pretty amazed at the accuracy. I don't wear it all day, every day. I wear it a little more often now, but that equates to maybe half the day and I don't take it to the gym or work with it on, so it's really impressive.

[M45]

My 114060 gains 5 seconds a week.

It’s good that it’s fast, because all I do is just pull out the crown and stop it until it is back with atomic time.

[jb335]

Wow OP, your Sub only lost 1 second over 30 days??? That's insane.

My SubC runs about +2 seconds/day. Totally cool with that.

[bigdavep]

Set my DSSD when the clocks went forward so that'll be the 31st of March. Just checked it and its +19 seconds. I can live with that.

I don't wear it all day every day either so i'm even more impressed.

[djyolky]

My new Explorer is about +2.5 seconds per day. Not really cool with that but what can ya do.
