Hi, can anyone tell me how to release the winding stem and button on this watch please.

Omega Electronic f300Hz DEVILLE CHRONOMETER

I have tried loosening the ss screw just above the rh coil but this has no effect. Also it looks the same as several others so I don't think that is the one.

Other watches seem to have a sort of dimple to press but there is nothing like that on this movement.

Am I missing something obvious?

Also is there any way without stripping the movement that I can remove the light staining on it. Just to make it look better.

Hi,

 

first of all - attention, this is not your average movement. You can make serious damage to the watch if you don't follow strict disassembly.

The red arrow indicated the dimple you have to press to release the stem. The Green lines show the screws you have to remove to be able to remove the oscillator module. DONT remove anything from the case without first remove this module.

I you cannot simply rub away the oxidation as it is on the oscillator module as there is a very sensitive 300 teeth 2.6mm wheel called the index wheel in this module and some tiny tiny fingers.  There is a bad scan out there of the movement maintenance manual (ESA9162) (just google for it).

If you have no clue, I would not go to far otherwise I bet you will damage it. If the watch runs, take immense care that you do not damage the coils. They are nearly impossible to get these days. I started restoring tuning fork watches of this calibre and it is not simple if you dont got a basic electronic understanding and a 30-40x microscope.

If it runs, close it. If its not. Look for a replacement movement. It does not have to be omega, it could be any other ESA9162 or ESA9164 if it has a date.

If you want to get rid of it, let me know I collect parts to repair some.

Greetings

Max

Hello Max, you have answered my question. I thought that ( only using my specs ) the dimple you mentioned was a tiny cross head screw but as you said it releases the stem.

I have no intention of working on this watch as it is running and keeping perfect time and anyway I know that it is beyond my capability to do so.

I have had it for a while but someone, not me has fitted a new stem and not got the length correct so there is a gap or not tightened enough as the button unscrews when i reverse wind it so I just want to attend to that.

I asked about cleaning the back of the movement as it is a bit stained. I wondered if anyone knew what to use with a cotton bud just to make it look better. Obviously I would keep well away from the mechanism, just gently clean the flat plate keeping the bud almost dry.

Any way thanks for helping me, I will fix the stem so that it is correctly fitted  and then sell it.

I have realised that the electronic Omegas and Accutrons which I have need to be got rid of before they get problems which I can't repair myself and I end up with watches that have to be sold for parts.

Thanks again and all the best, Mike

Hi, this is not even a similar technology. We are talking about a tuning fork watch and your offering a quarz movement.

      Unfortunately I'm not that lucky. I started on the train side and after I noticed the binding I pulled everything out except the driving wheel to rule everything else out. It still binds. I'm going to double check that the pinion is fully seated on the staff first, then if no joy I'll push the bridge jewel up a fraction of a mm. Fingers crossed!

      Thank you for the advise!! It worked. The setting screw was a lock/unlock to remove the rotor.

      I have that French tech sheet too, it is a little different than the English one (eg, it doesn't have the auto works diagram). BTW, it looks like you are looking up the case number in the 1979 ABC supplement. The 1974 ABC catalog does have the 3093 case. As you determined it takes the 1222-5 crystal.  When I serviced my President 'A' (which also takes that crystal), I was able to fit a 29.8 crystal from my DPA crystal assortment. Those are, in my opinion, a great deal. The assortment comes with 10 sizes each from 27.8mm to 32.4mm in 0.2 increments. I pretty much use them for any non-armored crystal that takes a high dome crystal. I think they no longer make them but Cousins has still has some in stock but when I bought them they were around $40 for the set and now they are around $100. Still, at 40 cents a crystal it's still a good deal. For the large driving wheel, I remember I once assembled the keyless/motion works first and when I placed the large driving wheel it was interfering with the setting wheel on the dial side as the teeth were not fully meshing and it wouldn't fully seat. If that isn't the issue I got nothing and am looking forward to see how you solve it 🙂

      Not sure, but just looking at it, it seems like the screw on the right may be a fake? The one on the left may not be a screw in the regular sense at all, rather a 2 position device, I think you need to point the slot towards either of the 2 dots and one will secure and one will open. Like I said this is just my best guess looking at the pictures.
