Dear respectable member,
My friend would like to purchase a Gold plated Cal 320 Chronograph. However he is not so sure whether the dial is original and the condition is decent.
He also would like to know how big is the watch.
Any opinion and info would be highly appreciated. Thank you.

 

Weird Omega symbol from this time and no top flat "A", isn't it?

 

So, no problem with the "A" but doesn't the OP applied omega symbol seems newer for a 320 cal?

 

Watchco had NOS service dial for 320 a while back. This could be one such example?

 

Yep, they're all more modern (read: 70's and after) fonts. Had to come back to this because it looks like it could be a model in the Museum Collection.

 

Thanks Mike.
