Do you see anything strange in this balance wheel?

Is it possible for you to take of the automatic device? You just need a good screwdriver with the correct dimension and take out the 3 blueish screws of the automatic bridge:

 

Yes I can do it. Then what?

Red line should turn in one direction regardless of which direction you turn the rotor.2017-03-13_12-51-51.jpg.b06b34353a8b91135f58ea7545cb1e5b.jpg.42e89c9e77f1f924ff0b928962be930f.jpg

What are you indicating with the red line? The  red wheel or the bronze ratchet wheel? Because the red one alternates direction while the bronze one is skipping the click, it seems.

Any idea of why this skip could occur?

It's difficult to say, but as has already be suggested, my first guess would be wear to the auto-wind mechanism. It would require closer inspection. 

If this was my watch, I would probably find someone like Mark Lovick to send it to, but that's just my opinion. Saves you the hassle of dealing with Rolex who are trying to maintain a monopoly.

I took the rotor apart and took pictures then I assembled it back. One thing for sure now the ratchet wheel is not moving at all, only by manual winding. It seems to me that the part under the rotor is ok. Do you see anything?

I mean the bronze ratchet wheel. That should turn when you rotate the rotor? Are you sure you can work on this kind of movements? If you don't understand how a automatic watch  works?

How can you see that the reverse wheels are working? They turn? 

But do they click or engage? And transfer the power from the rotor to the ratchet wheel? And the mainspring? 

There are small little clicks inside the reverse wheels that need to engage the small ratchets on the outside of the reverse wheel?

I have only seen your video on an iphone, but I think the driving wheel (the wheel with the four holes in it) is turning when you move the rotor. Is it possible, that the connection within this part, the connection between the bronze driving wheel and the little wheel on it, is loose?

Looking at my second picture it seems like one tooth of the center little wheel is slightly bent, at the top.

Yes, one of the pinion leaves looks slightly bent. Now, if this is true then here is some speculation:

- The auto winder may be broken as a result of extreme force against the winding pinion.

- Either the auto winder tried to wind the ratchet wheel which was somehow fixed, or the ratchet wheel wound against the auto winder pinion*

* looking at the direction that the pinion leaf is bent, I'm wondering if either the auto winder reverser function failed and it tried to wind the wrong way. Or, when manual winding, the auto winder jammed which meant that the ratchet wheel damaged the pinion while winding.

ok but could this bent leave affect the whole auto winding to not work at all?

good point, I'll disassemble it again and check that. But I will do it in the afternoon. I'll post back.

P.S. let's say the connection is loose, a new wheel is needed or it can be tightened?

Well guys, I contacted authorized Rolex Service center that sits 100 Kms from my home town. I decided to go there tomorrow morning and let them check it. I told them about the auto winding not engaging the ratchet wheel. They told they will be able to diagnose and fix it while I am waiting for as little as 100 euros + parts if needed. Unless a complete servicing is required, which I think it's not.

I am a novice so please excuse my input if it is rubbish. But might the fact that 'something is slipping' point to a problem with the mainspring or problem with it being unhooked? As I say I'm a novice but I read of a similar issue and wanted to share that with you.

It would be a good idea if the watch wasn't winding at all, but since it winds and runs fine when hand wound, IMO it rules out the mainspring (I'm also not a pro, so take this with a grain of salt ;) ).

Good news! Make sure you ask them what they did after they fix it!!!

Technician inspect the watch carefully, many parts to be changed, proposed full service. Accepted. Regarding the automatic device he told the pinions of the reverser wheel are damaged. Also told the beating of the rotor has to be replaced, one jewel is crooked, other parts worn out etc.

Main Spring unhooked perhaps?

Automatic mainsprings don't hook into the barrel, they are meant to slip to avoid damage to the winding gear. If it was unhooked from the abour, then it wouldn't wind by hand.
Seems the problems been solved anyway, just general wear and tear.

Thanks for telling me. I have not worked on an automatic yet so obviously these a lot to learn [emoji51]

Hello there, the watch was serviced for 640 euros, they gave 2 years international warranty and a 5 years warranty from the lab, they are very confident in their work. They replaced a lot of parts in the movement, reverser wheels, driving wheel, ratchet wheel, some other wheels, the barrel, the mainspring many screws and some other tiny parts. They put a new glass and crown and new gaskets. They also regulated the timing, polished and pressure tested the case. They have a video online of their lab if you want to check it:

The price doesn't sound too bad considering all the replacement parts. I hope this finally puts the issue to bed. ^_^

    • does anyone knows what type of battery this digital Watch takes?  
    • Hello good watch folk ,I  just fancied a light hearted discussion after my head was starting to spin over Epilame 😅. Specifically I'm meaning the sale of vintage watches, say nothing past the 1980s market. The stuff we see on ebay and other similar sites and found at carboots, curio shops etc. And are  we thinking its reaching a peak volume ?  Younger generations clearing out passed parents and grandparents possessions.  The younger folk are not as sentimental as the old fogies ( I'm now nearly at an age that i used to think was old fogie age ). When might it have started ?  i often wish i discovered the hobby much much sooner when selling your grandfathers pocket watch at a boot sale for a few quid was just a way to offload some tat. And when might it slow down. Thoughts anyone ?
    • Yes i did eventually realise that the oil will act as a barrier, I'm sure the discussion will continue. Ive had two oleophobic coffees ( added coconut ) and in the meantime i have this just delivered to take my mind off epilame for the time being. My favourite type of dial, its a beautiful looking watch traditional English made and it runs,  the ticktock is phenomenal,  i can hear it across my living room .  You wont believe how much it was. Thats interesting about synthetic oils , i thought the same, going from a 2 year service to 5 years is a big drop in income for service folk.  I expect some did well when they embraced the use of synthetic,  probably drawing in more customers than those that didn't use the new fangled substances , i bet fairly short lived though. The more frequent service makes more sense to me, not for just the service but for the regular check up inspections that might pick up impending faults. As far as epilame goes, wouldn't it be great to be able to fumigate the complete movement in a sealed jar of heated stearic acid, 🤔 now theres a thought 😅.
    • Imm going to close the discussion by attaching the photo of my super-titanium after several vicissitudes finally working. Purchased as not working I replaced the battery and for a stroke of luck I found its semi-new solar panel which, having verified its operation, seems to recharge the accumulator perfectly. I had taken this watch almost by bet, with 40 euros I brought it back to life. The initial half idea was to resell it to finance another purchase, but.. it's definitely a nice item. It would need to check the impermeability but it's a pleasure to see it on the wrist 😃
    • In fact the secret is to go gently and find the way without forcing, and the movement enters without problems
