Hello,

I have together with a friend of mine, an old Omega and we are trying to figure out what is the best way to restore it in a better condition.

What I found by myself since now is that the watch is an Art Deco model from '30-'40 and the caliber must be a T17 or 20.

Any help and advice will be much appreciated.

Thanks in advance and here are the pictures:

 

it is a parts donor watch as the case is gone...

 

I agree with Erich regarding the condition...

It is a CK 730 with T17 Inside.

Here in a 1938 catalog :

Mine, from 1936, says hello :


Note that CK 730 was also produced earlier with a 20mm Inside, but the hands and dial style of your watch is typical for T17.

Looks an expensive restoration.

 

Thanks for advices.

Do you know how can I open the case?

 

There should be a notch in the caseback by the springbar.
Use a caseback knife

or an appropriate tool to gently pop the caseback from the case.



I would normally refer you to a watchmaker or a more careful method, but frankly, you aren't going to hurt that case.
