Accuracy of your Rolex if not worn

[Eppi]

I tried a test with my new OP. I left it still in my wardrobe facing upwards and i kept track of it.
I haven't worn it for 15 days.
Every day is 5 seconds fast, consistently.
I wind it fully almost every day but still is 5 seconds fast.

Has someone ever tried to see how his Rolex would perform in a still position?
Does it keep the performance as it was worn every day?

OP - I’m not understanding your comment. No Rolex would function if unworn for 15 days. In fact, in most cases after max 3 days it would stop.

Meaning I just left it in the closet but still wound it every evening 25 times

That wasn’t in your original post. Now it’s clear. It’s common knowledge that when mechanical watches are left in different resting positions the movement will operate more or less efficiently. The outcome of this is losing or gaining time in most scenarios, depending upon a given position.

If your watch does happen to keep exactly the same accuracy when left in one position as it does when being worn, then it's just pure luck. Watches are designed to be exposed to the effects of gravity from multiple angles while being worn and moved: that's why they're tested in 5 positions - to simulate real world use - and are adjusted accordingly to give the best mean result.

Exactly that.

Don’t most watches gain time dial up?

[amphr1]

5 second fast maybe outside of parameters. But between a watch that's slow vs fast I would always prefer a watch that's fast. That said, you should test it by wearing it. I bet it'll be dead-on or closer to 2 second a day fast.

[Jackie Daytona]

That’s pretty good you didn’t wear it for 15 days, picked it back up and it was only 5 seconds off.

[Eppi]

Hah no, I wish!
It was 5 seconds fast EVERY day.
I was wondering... if I wind it 25 times every day... shouldn't it keep the time within specs regardless of if its use? (Worn or unworn)

Read post 17 might explain how a mechanical movement works.

[Tim Plains]

I know with Omega, it's an average of all positions tested, so a movement may be way out of spec in one position but it still gets METAS certification if the tests all average to between 0 - 5 seconds. Maybe Rolex is the same.

[HideMyWalletPlease]

If you are not wearing it then the accuracy does not matter.

If a tree falls on the forest, does it make a sound if no one is there to hear it?

Seriously though, if the watch were on a well designed winder it would remain accurate from the rotor moving.

I find it does work even with a newer movement.

I absolutely use this. My '77 1603 can vary a little bit more off the wrist, but otherwise stays within the +2/-2 depending on the temperature I find.

[OrangeSport]

Face up speeds 'em up

Also, if it's not fully wound (no idea what the PR is in that watch) it tends to run faster (in my experience)

[George58]

My 18078 is dead on plus2 know matter worn or not and any position My pp aqua runs all over runs differently wearing it and its influenced in how it's stored never worse than plus 10 I think because it beats a slower rate than modern movements now

If people don't appreciate the mechanical marvel of the micro engineered timepiece then perhaps a mechanical watch is not for you.
I'm glad my life isn't timed to the second.

Have to agree.

[macrowatch]

It will be 100% accurate but only twice a day. Ha.

Yes and Yes.

But on or off the wrist there are many variables like friction, mainspring power-reserve, gravity resting position, different temperatures, subtle changes in oil lubrication and so on. But consistency is one of the most important things with mechanical watches, and no purely mechanical movement any price or brand will keep 100% perfect time. When resting off wrist flat dial up or dial down the balance staff runs on the ends of it's pivots very little or no added friction. Thus the balance wheel has a very slightly higher amplitude so will make movement run very slightly faster. When watch is off wrist vertical crown up or down or the balance staff pivots runs on the sides of the balance pivot causing a tiny more added friction this slows the amplitude so will run very slightly slower.

Great explanation. Thanks.

Yes... I knew that... is it 5 seconds too much? Or is it inside the possibility of technical errors that you just described.

Well 5 seconds out of 86400 seconds in a day on or off the wrist would not concern me in the slightest, consistently is far more important. Even after this new precision Rolex test on a machine to -2+2 seconds test results below would still pass this new precision test. Your watch is fine just wear and enjoy it in good health now thats far more important.

Position Of Watch seconds Per Day
Dial Up +2
Dial Down -1
6 o’clock +3
9 o’clock -3
3 o’clock +5

You seems to know a lot :) ... finally...
Final question for you.

Do you think replica rolex could perform inside COSC specifications?

Or they will always underperform

Well in the real world most movements today could match the Swiss COSC test of AVERAGE -4+6 seconds a day. Even some Chinese Seagull movements like the ST19 after very careful regulation can run to or inside the COSC spec. Cost of movement around now $70 but will have to have more regular regulation to keep it there. That's the secret of accuracy how well the movement is regulated that matches the owners wearing habits..

PS One thing we never talk about in the Rolex forum is replica anything.

I'm reading between the lines here, but it seems like you are not really asking about timekeeping accuracy in this thread, but about the authenticity of your watch and its movement. I'm not sure where you purchased the watch, but I strongly urge you to have it inspected and authenticated by a Rolex Service Center. Otherwise, I don't think you are ever going to be happy with your watch.

[SaintMickey]

Mine stops at 48 or 70 hours if not worn.

[Rocketman39]

If I were You, I would pitch it and buy a New one. They are easy to come by and Rolex makes almost a Million of them a Year!. Just saying, for a Friend ! Merry Christmas and Happy New Year ! !
