The watch may be authentic as per the extract but the dial has been redone-badly!
Julian
1) Patek stopped adding "&Co" on the dials in the year 1948
2) I NEVER saw a different spelling of "Geneve" like "Ginebra" on an original Patek dial
(and I have seen a lot of PPs while collecting watches)
so you can be sure your watch was not delivered with this particular dial - it is a wrong redial.
Mostly the "print" on Patek dials (specially vintage) is not done with black laquer but executed in black enamel
e.g. minute and seconds tracks, but not always the brand´s name - this is added in laquer.
So it is rather easy to "restore" this kind of dials compared to dials on which everything is printed in laquer...
As a restorer you can "wash" them with aceton or similar , do a replating etc. - finally you only have to add the brand´s name and "Geneve"
in black laquer... some ignorant restorer used the Spanish spelling instead of the French one.
I think this is the explanation for the recent situation.
just my 2 (euro-) cents
