Thank you OF for the space and thanks to all that you read my post.

With the help from a friendly member from OF ,DirtyDozen12, i found new information about my Longines.Movement was from a stainless steel Longines ,the 18k gold case is original but about refference from caseback he have doubt.
For that reason if someone is interested to buy it,i will accept a lower offer.
Thanks DirtyDozen12 for help and thanks OF .
