Thanks @watchyouwant
I'm trying everyday to train my eyes but did not even notice the 377 on the case
Thanks for pointing out too to the missing screw... Yes my watchmaker should be able to manage that !
Just for me to understand why do you say 1949 ?
Just asking because the list of reference number I have gives me this : "11,000,000 – 11,999,999 1947" ?
