The Golden Writings is Wowowowow!!!
As for the ' 67, I saw one ( official origin ), with applied numbers, painted indexes, and circled date window...
" Yours " is a Lecoultre.
Maybe this explains the difference???
BUT I'm a bit amazed, as I have the production numbers for the Polaris 1967, and there were only...: 9!
Best, my friend...
