Thanks CLB. As I do like Rolex watches although I prefer Omega coaxial, very frustrating to have a bent balance staff on such a classic watch. Did you see the original bent staff? Was it replaced?  If so the repairer should have shown you the bent one. Did you see it?

The oils drying out would take quite some time as the oils used are of a very high quality. How old is the the watch?

When I viewed Marks strip down of the Rolex GMT master Mark pointed out that the movement had been over oiled. This could be another possible cause for the inetermittent stopping.

I hope you get this sorted. Please keep us posted on developments.

Thanks for the support.  I was not shown the bent balance staff.  I was just told it was bent and replaced.  The watch was purchased from an AD in 2018 and I purchased it in late 2018 from the grey dealer.  I dont believe the oils are dried out.  Not on a watch so new.  Over oiling could be possible and could happen to anyone.

Since I left the local repair ship the watch has been working well.  No stops so far.  He did de-magnetize it which may have fixed it?  Maybe whatever was binding things up loosened when he opened up the watch?  Time will tell if the problem is fixed or not.

I will definitely let everyone know if more problems persist.

Thank you all for your help and advice.

So once again the watch has stopped around 8:30 at night.  I have pulled out the crown to keep the movement stopped.  I am going to reach out to the dealer and see if he wants to take it back in.  Hoping that by keeping the movement stopped whatever is knocking it loose won't get it moving again. 

I am noticing the watch stops around the same time  (around 8:30 at night or between 7-8 in the morning) so I wonder if a gear at a specific time is causing a problem. Can anyone confirm if any specific gear is regulated or has a 12 or 24 hour single rotation?

Hi,

Well, the most obvious wheel is the hour wheel which carries the hour hand.

If it's both morning and night, then it seems less likely to be calendar-related.

1-Stops at 8.30hr or 20.30 or both?

2- If at 20.30 hr, a fault is in at date jump mech. 

3-If at 8.30 fault is at canon pinion and hour wheel.

Hands rubbing is unlikely to be the issue here, since two watchmakers have taken a look at the watch.

Best wishes.

Its happened both night and morning.

Does the hour wheel have one revolution every hour or 12 or 24?

Every 12. It attaches to the hour hand.

That is what I was telling you before. A watch that had stopped once will stop again.

Dry oil (that certainly is not the case here, Rolex uses synthetic oils lasting a minimum of 7 years), or magnetization do not  stop watches.

Do you remember if it was stopping at the same time even before you sent it for repair? Is so, that indicates you have been lied about replacing the balance staff, which is demanding work, never taken easily.

The good news is that there are (few) reputable, independent watchmakers able to repair without overcharging based on you watch brand and price. Then draw you own conclusions.

If the fault is at canon pinion or hour wheel, it should pick up and go as you advance the hands past the fault.

I have tried advancing the hands when I the watch is stopped and it does not make a difference to get it running again.

That makes sense. When you advance time with the crown, the gear train will move, because it's firmly stopped (or "hacked"), and the hand wheel move independently thanks to the cannon pinion slipping on the center wheel.
Then what happens is that eventually but randomly, the mainspring force wins over whatever fault and get it ticking again.
Again, if don't trust anymore your seller you should be looking a a reputable watchmaker.

I'm going to give them one more chance to see if it can get fixed.  If that doesnt work I will have someone else work on it.

Thanks again for all of the help guys.  I will let you know how things go.

Sorry I meant to wrote, will NOT move.

So after a few weeks waiting for my dealer's watch repair guy to return, he called me today to say that the local guy did something to the timing which required a full service on the watch.  He said that when he had the watch the first time he did a full service on it as well.  I am getting the watch back tomorrow and hopefully this fix will be permanent.
