Beat error of 3135 Rolex


Scottrb1

Recommended Posts

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

@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 .....

@Scottrb1: Have you been caught red handed glancing on your phone ? :mad:

    • Its a big item Michael and a lot that could go wrong with the process of getting it to its new location. I once helped install one of these units into a conservatory that i had built. It was big and bloody heavy and took six of us to get it in safely. If you have sliding doors and you need to remove the whole frame then that may or may not go well. But i would advise getting a professional in if you have little knowledge on the installation of them. The glazing of the doors could well be 6mm laminated glass which again will be heavy very heavy if the glazing units are big. The glass would also need to be set up and packed correctly to open the doors properly more so if they are unframed and the sliders are upvc. Seems a shame but if no one is biting and that may be due to having no warranty i guess the only takers might be someone that installs them for a living and knows how to repair. If its fibreglass just be careful, i sometimes have to cut fibreglass baths out and they are nasty to work with . Thick gloves are definitely recommended,  not fun picking out fibreglass spells two days later that have started to go septic. Good luck with it all matey.
    • I don’t know anything about this product, however assuming you have it if you put a drop on a mirror or piece of glass lying flat on a table and leave it to evaporate if it leaves any sort of residue it is not really suitable for watch part cleaning.   Tom
    • Well I put the spa on Gumtree (selling service) to try and sell it as it only needs a recirc pump to get it going. However, it weighs circa 250kg, so there's 4 fairly strong guys, and I would have to remove the sliding door in the room completely to be able to get it out, as well as clearing out a multitude of potted plants and the Alfresco outdoor setting to be able to get it out. Then move nearly everything in the back of the garage to be able to push it through to the front of the house. I would also need to hire furniture skates to be able to shift it around as carrying it is out of the question. Then someone would need a trailer to get it to their place as you won't get it on the back of a ute. So, the only answer is, out with the reciprocating saw and cut it all up into manageable pieces. Crying shame as it is in really good nick. I was only asking $1,500 and only got two bites, but it would only take something to go wrong with removing the sliding door etc that everything I make on the sale could go out the door on repairs etc. It would have been nice to be able to turn it into tools etc, but que sera sera. I don't know about the rest of the world, but there just seems to be very little interest from people wanting to buy things secondhand.  
    • I would like to see the movement. The watch is the movement. Anyone can print a name on a dial and sell it as "the maker".
    • Thanks for your answers! There seems to be a contradiction between these two answers, so perhaps I need to clarify. The flat and convex jewels look identical on the side facing away from the pivot shoulder. That is, there is an oil reservoir. I don't know if that changes anything but I thought it was safest to clarify since I didn't include a picture of the jewels from the opposite side.
