Looking at this 26.5 T3 P.C movement I noticed the top and bottom balance jewels are suspended on a spring at each side, I have not seen this type of shock protection before can anyone tell me what it is called? Will the movement requite a special balance?
The dial is copper coloured and is not due to discolouration of the lacquer too.
Thanks Michael

 

looks very strange to me; like an former eastern bloc watch without access to parts.... omega, in my opinion, would not have used that kind of screw for the spring. the hole should be done in a way, that the screw sits flush with the balance cock surface. but, that is just my opinion; have not seen this before. to me it looks like that it props up the regulator part and is not part of a shockproof system.... nice dial, BTW ! kind regards. achim

 

Hi Achim.
The whole of the regulator and other parts are suspended on this spring, it is pretty odd.
Thanks Michael

 

A similar watch can be seen here with the same screw under the regulator.

And another one here> http://www.invaluable.com/auction-l...omega-ref.-2165-military-watc-60-c-53441bf93a

 

My Bestfit catalog shows a similar shock resist system called Eterna L. Anyone?

 

Interesting. Thank you.

no, movement is fine. not a franken movement; whatever that means......because I have not seen things before, does not mean, they do not exist. just the craftsmanship is not what I`ve seen from omega so far. but the eternal did exist; see link above. kind regards. achim

 

The shock resist system on the Eterna in the link looks very much like the shock resist on the Omega.

 

I have several Officers and the copper one in the link is mine. The Copper dial i agree is original in this color have seen a few of them.



On this Officer it seem to be similar with ours regarding the movement, this is also the oldest Officer I have.



I have check with some of the other Officers 2299 and they do not look the same, here is an other Officers:



I have also a 2165 also early, but it has a 26,5 T2 i guess

 

I do not know the name of this type of shock protector but I am sure I have seen it before... IMO it is a legit early Omega shock protector

 

The Eterna shock protection used in the WWW (Dirty Dozen) Eterna cal 520 is of a somewhat similar principle as pointed out by @Canuck. Looks a bit more developed. Production year is 1944 so it corresponds well to the period of the Omega Officer.
I used to own an Officer, but that had incabloc shock protection.

Here are a few shots from the service of my Eterna:


And my previously owned Officer:

 

That's what I thought too. Check this out:-

Forgot about that one, thats mine too

 

Hi
I also think it is Omega legit. I have one 26.5 SOB T3 with the same device. I ll post a pic this evening.

That is why I love watches so much Achim, always something new to learn, if we knew it all it would be a bit boring.
Thanks Michael

 

Thank you for all the help and replies so far

 

HI,
Went quickly through my spares/project boxes and can confirm that it is a legit 26.5 SOB T3 PC.
Roughly here is the evolution of 26.5 :

The first, 26.5 SOB :


then first transformation : 26.5 SOB T1. Easyly differentiated from its predecessor looking at the mainspring click :


Then second tranformation, 26.5 SOB T2. Same mainspring click as on T1 but no more screws on plate holding the balance staff jewel :


Then there was a 26.5 SOB T2 PC, which I didn't find in my spare boxes. Will have to look at the watches in my collection

Then the third transformation : 26.5 SOB T3, no visible difference with the T2 design :


Then the 26.5 SOB T3 PC with its parechoc like in Mike's pictures:




Finally, the 26.5 SOB T3 PC T1 (first transformation of the PC) also called 100. Can be recognized with its incabloc style parechoc :


Interesting to see that the drawings in AJTT are, for some strange reasons, wrong, and do not reflect those evolutions.

Please forgive me for posting bad quality pictures of dirty non working calibers, I went quickly to the spares/projects because I prefer to avoid opening the working ones of my collection, the purpose was to show differences between successive transformations. Sorry also if I didn't use the right technical words in English, I would use more accurate words in French.
