Rolex 3135 Regulation

[Scottster]

Last year I serviced my Rolex. I thought it has been running great until I finally bought an electronic watch timer. I have spent the last few months regulating watches that I thought were running great. The timer said otherwise.

 

My rolex is running about 1.0ms out of beat. I understand how to adjust the rate with the microstella but I cant find any good information about how to adjust the beat.

 

Thanks for the help.

Someone more knowledgeable than me might see different but I would say its not an out of beat issue but something is amiss one side of the pallet/escapement. I think I see a vid of Mark's with this type of fault & it was a loose pallet jewel.

There are guys more experienced than me might have different views.

That is not the vid I was thinking of. However if you look at the reading Mark was getting with that vid it has an out of beat watch BUT the reading on the timegarpher is different to the one Scottster is getting. In my opinion there is a fault with the escapement/pallet jewel on his Rolex. If it was me I would strip & clean & re-lube the escape parts of the movement.

I did have similar fault a while ago with a ETA movement.  I had forgot to lube the pallet jewels & then lower balance jewel when re-cleaned & lubed correctly the fault went.

Good advice. I think there is a problem also. I will disassemble it as soon as I get a chance and go from there. Thanks for your input.

The watch is out of beat but as CB says there is also another issue.

 

It could be the hairspring coils are dirty or sticking due to magnetism as the lower line is inconstant. This means something is happening during one vibration causing this. Check hairspring, ruby pin (is it clean), pallet horns (I have seen these where unevenly), pallet stones, pivot holes for balance, pallets and escape wheel. Make sure pallet stones and roller ruby pin is not loose.

 

Most likely culprit is dirt, magnetism or incorrect lubrication.

Thanks for the advice. Whatever it is I'm going to disassemble it, clean and service it. All I needed was an excuse. I'll let you know how it goes. Thanks again.

You adjust the beat by adjusting the regulating arm on the balance cock. Rate is adjusted with a micro stellar

One of the nice characteristics of a timing machine is to see things that cannot be seen any other way. Then for diagnosing problems anything common to both pallet stones shows up with both lines. Anything that's unique to only one pallet stone shows up is only one line being affected. I've attached some images out of a timing machine manual. The most common place I've seen this is the exact same location that clockboy Is pointing out Improper lubrication on the pallet fork. In other words you just lubricated the escapement you put on the timing machine one lines a little rough you need to put a little more lubrication on problem goes away. The problem is you shouldn't see this on a watch that was serviced such a short while ago? Then if it wasn't a lubrication issue there's something wrong with one of the pallet stones. Old lubrication the was never cleaned off chipped stone something wrong with one of them.
