Thank you to all for your answers!
However the writing was not reprinted and the dial never washed or cleaned (I know for sure, buyed from first owner look at case with the original oxydation.....
Anyway thanks to your answers I searched more on the web and I found another one on the Web (placed the link below) with the wording with same characteristics...
Hi there, without going into originality questions it’s got a very pretty design and linen texture.
But how does the case tell you about the dial, except to say that the level of (very nice) patina on the gold means the dial shouldn’t look brand new?
How do you know that the “other” watch you linked to is not the same? Looks like the exact same example to me, only serial numbers will show it’s a different one.
How many hundreds of Longines dials have you seen that make you so sure about Longines dial making processes in the 1950s?
I know when you’re happy about a new watch there are some statements you’d prefer not to hear from other people.
However I’m sure those experienced collectors made them with a good intention, to warn you while there is still time for you to return your watch or negotiate with the seller if the price was excessive.
Also, If you make assertions which can mislead less experienced people, IMHO seasoned collectors have an ethical obligation to correct the record to avoid readers being misinformed.
It takes time and experience to spot redials but a great place to start is @ConElPueblo’s very good sticky thread called “Learn How to Fish”.
And for correct Longines dial signatures and logos on a 1950s Longines textured dials, there are a bunch which were posted in the thread entitled “Claw lug Longines”. The thread is quite informative on the differences between a thickly inked redialed logo and the very fine logos which are found on original textured dials.
That being said it’s a lovely looking watch and if you’re happy to wear it for the price you paid you should enjoy it.
Best regards
