Hi, just bought a Omega caliber 266, and in the back cover is stamped a star.

Anyone know what can it be?

Thanks

 

Shot in the dark.. but I'm guessing it has to do with the timing competitions..

But a hidden stamped is only for watchmakers....

So, nobody knows certainly........watch case manufacturer like HF....


Thanks

 

Just an observation from the OP's watch and from the thread I posted above is that all the case backs with the stars also state Fab. Suisse

 

Could also this symbol represent a case manufacturer, like the star ?

 

Is it a keyhole?

 

then it is a patent I think

 

I don`t know, but you can see this symbol in a lot of cases from the 60's.

 

That's the makers mark for Ervin Piquerez S.A.
It represents a simplified diver's helmet.
