I am in the United Kingdom and own the Omega Constellation electroquartz f8192hz.
This was given to me by my fatherinlaw in Austria in the early 1970's not working.

It has been stored a long time and I recently found it and looked inside it to clean and replace the battery etc- and saw a horror picture...

Serial 317324**(starred for security) on the winding block..

The number stamped on the backplate is 196.00* (starred for security)

The circuit board is damaged and needs to be replaced..or repaired at componant level.
part number appears to be :-

A16041 on the metal under cover and 105 on the pcb top..

I think it is the speed regulator as a ceramic variable resistor is broken .

I would like to repair or replace the broken pcb and some missing screws and a new back seal....I can do micro soldering and electronic repairs at chip level..
Does anyone know the values of the ceramic resistor or what 6 pin chip is on the PCB

Can you please help me..
Many Regards Allan

p.s. Omega Switzerland cannot help with componant values...

 

Yes the writing is GEH-B21 and and under it is the Omega sign 1300

 

Does ANYONE have any idea of the two componants I need....

 

I think I have found the chip?? an ODC04. for CEH I found the same pic..lol

 

I don't know where you might be able to find that 40-year-old chip. That was designed to handle an odd frequency. Almost all the manufacturers have now settled on 32,768Hz. And if there was physical damage to the board, I would be careful to check the other parts. Are the coils good?

All the circuit does is move the resonator. After that, the resonator turns the index wheel with a very sensitive ratchet and pawl system (which was designed to run on the 1.35V mercury cells which are no longer available).

So simple (maybe for you) repair of the PCB might just be the beginning of the restoration.

I have dicovered that Rolex also used the same PCB maybe I can source one from there.???

 

Thankyou..Yes I have seen them but do they use a beta21 control...
