Beat error of 3135 Rolex

[Scottrb1]

Hi everyone.

Looking for some advice.

I recently got a timegrapher and tested my 8 month old Submariner. It seems to be running -2 secs a day and the Beat error is between 0.4-0.6.

I went to my local AD who tested and confirmed my findings and said I should send back go RSC asap.

I am not sure what to do. Do I really want my brand new watch opened up..

What advice would you give ?

Is it within spec? 

 

Thanks

Your Rolex is just out of beat by 0.4ms is not bad and really pretty good. Rolex guarantee +/- 3 secs a day so it is within spec.

@Scottrb1: Welcome to the forum

I'm a bit confused about your question? Your Rolex 3135 seems to be running -2 seconds a day ......?

Seems to be running, or does it run -2 sec a day on your wrist? And in which position does it run -2 s/d? What about all the other positions? The same counts for the beat-error.

A beat error of 0.4 - 0.6ms is, according to the information I have, within specs, so is the daily rate when taken over all the different positions

Then the question whether you want your watch to be opened? It depends on who does it.... If it is an official Rolex service center, and they deem it necessary to make adjustments, then they will replace the O-ring and test the watch for the required water-tightness. Make sure however, it's an official Rolex service center. I have bad experiences with Rolex dealers with their own watch-repairers.

Then the next question; what accuracy are you after? Quartz precision?  -2 s/d on your wrist seems for a mechanical watch reasonable/pretty good and if the watch runs -2 s/d constantly, then don't worry too much about the small beat-error ..... it doesn't hurt the watch.

So, yes, many questions open .....

I noticed one error / assumption in my reply; that your Submariner has the 3135 movement !? I'm not sure which movement is in these days Submariners. Perhaps your movement has some tighter tolerances, but still ..... if your watch runs constantly -2 s/d on the wrist and the beat-error is between 0.4-0.6ms, it can't be that far off ....

The reference sheet I've given you is for a 3135.

Try to find out which movement it has and what the Rolex specs for that movement are.

Rolex specifications are interesting and there seems to be some minor variations? So I'm looking at a Rolex specification sheet for the 3135 first criteria 15 then the second criteria is -1 to +5. then the specifications are averages of positions or averages over time.

Then there's the other minor little thing which timing machine did you use? the reason for the question is if your timing machine only reads to seconds you usually have an error of plus and minus whatever the smallest digit is. So if you want to actually know the second you need a machine that measures to the 10th of a second. Then whatever it's time standard is should be of suitable accuracy to maintain that resolution of accuracy.

then as wonderful as timing machines are there really not the final test of what the watch does for timekeeping. The final test is to set the watch to a decent time standard. In other words the time standard has to have time better than the Rolex. Then watch the watch over several days and see what it does. then ideally it should be on your wrist not sitting in one position.

Probably nothing to do with your Rolex, but I thought it is a funny story;

Back in the early '70's an uncle of mine (successful in business) bought a seaworthy motorboat. It wasn't a new one, but still very nice; radar, sonar, radio-equipment and all the rest of it. It had two huge inboard Volvo petrol engines capable of propelling the boat up to an awesome speed of 60 km/h. It had always been sealing fine and it was still sealing great.

My uncle thought, since we were dealing with petrol, to install some sensors, or sniffers if you like, underneath the hatches of the motor compartment to detect any gasses or petrol leaks. On the control-panel were flash-lights, whistles & horns.

Anyway, we went on a weekend tour with him and every hour or so, all the alarms went off. Halve in panic the engines were shut down and the hatches pulled off for venting and investigations.

What a nightmare that boat became .....

Hi Scottrb1, your Rolex looks fine to me and in spec.  I would not touch it. If you want +3 secs per month then get a Fake Rolex Quartz like mine. Regards, Mike.
