Setting a Rolex for accuracy.

[Andad]

If a Rolex is gaining or losing time and is set to spot on local time it will never ever show the correct time as it is always gaining or losing as soon as the crown is pushed in.

To fix this and for an example:-

If my Rolex is gaining say 1 second /day I will set it 15 seconds slow knowing that the accuracy is improving till after about 15 days it will be spot on. After another 15 days it will be approx 15 seconds fast I can then set it 15 seconds slow again.
This doubles the time between resets and at least it does read the correct time at some point. I also know that during any given month I am never more than +/- 15 seconds and at the middle of the month I am about spot on.

good one eddie . One more post and you have a thousand posts

Is this the case with your new GMT II??
Is that still within the COSC specs?
Just wondering...I'm dyslexic and things like this confuse me sometimes...

[Andad]

Yes, 1 second/day is well inside COSC specs. My GMT 11 is running about + 8 seconds/week but is only worn about twice a week so I don't know how it would average out if I wore it every day. I wore it today but SD tomorrow.
As per my own suggestion I set it 15 seconds slow at the beginning of this month and when I put it in the safe about 5 minutes ago it was one second slow.

Eddie,
My GMT II runs -1.75 sec per day so I do basically the same thing. I set it one minute fast and it's good to go for a least a month.

Yes, just saw that. 1002 posts and probably lucky to still be here.

Hi Dan,

I posted this because I got the feeling that a lot of Rolex owners set their watches exactly on the correct time.
This thread might confirm or refute that thought.

I set mine to -30 sec and when it reaches +30sec I reset it. so I am always within 30 sec of official time.

My Rolex SS Sub date must be average! it doesn't gain or lose time.

Then please write 10 times on the blackboard:

"I MUST wind my neck in!"
"I MUST wind my neck in!"

Me, I've removed the mechanism completely and set the watch to 12 o'clock.

It is right twice a day. For ever!

Probably prefer to crawl over broken glass wearing a Rado.

Be my guest!

I have been so kind as to prepare the road for you and also added something that makes it more comfortable for you

if I wear my Folex it gains 30 seconds per day, if I leave it on the table when it's laying on it's bracelet it gains 65 seconds per day, if I leave it on the table when it lays on the 9 o'clock position it looses 15 seconds per day, and I'm satisfied.

Must admit you guys make me smile with all the timing to the exact second afraid if you want exact should have bought a quartz.Now if your Rolex gains, or god forbid looses a few seconds a day,its hardly life dependent or life threatening.And I am sure a few seconds fast or slow is not going to make any difference to your daily life.And a simple reset if watch is running to COSC spec once a week take just a few seconds (excuse pun).And just think of this when you check or reset your Rolex or any other watch.Now today any modern day wristwatch chronometers are, by the almost 300 year old 18th century navigational standards imposed on John Harrison H4 watch,quite laughably inaccurate, even by todays standards.How about just 5 seconds slow after 63 days at sea,not bad for a almost 300 year old watch.So guys chill out relax life's too short to get annal about a few seconds deviation in a watch.Remember this in 24 hours, the escapement of a mechanical watch pushes the gears 432,000 times. Since a day has 86,400 seconds, even a watch that runs five minutes fast or slow each day has an accuracy of over 99.6 percent! A finer mechanical watch that gains or loses about nine seconds a day or about a minute a week has a breathtaking precision of over 99.99 per cent. This is very high precision, given the fact that the movement is constantly affected by the earth's gravity, metal expansion and contraction, temperature variations, subtle changes in lubrication and friction, shocks etc.And yes modern life today is governed by time but not to the absolute second.Yes we spend our lives on the run: we get up by the clock, eat and sleep by the clock, get up again, go to work - and then we retire. And what do they give us? a bloody clock.So guys don't get annal with just a few seconds there really is more to life believe me.

I am still in the ownership stage to determine exact time gain per week. Once I know, I will use your method. Thanks! Cheers, Bill P.

Hey Padi,

I am glad that one moderator is smiling at something I said.
I was just trying to get any of my Rolex to tell me the correct time at least once during its existence but the main aim was to keep the unscrewing of the crown to a minimum.

What method do you mean?

The method of not being anal about timekeeping?

Well even a broken or stopped watch with the hands in place is going to show the correct time at least twice a day.

AND you keep the unscrewing of the crown to a minimum, too!

Well the wife has a ladies Tudor oyster from 1962 and yes it has been serviced many times but by my watchmaker friend.And the crown tube has never been replaced.And my son now is still wearing a old manual wind OP ref 6426,from 1960 thats being wound nearly every day.And as far as I know has the same tube and crown.So I am sure once a week setting will not wear the threads on a modern watch.
