So the listing says “Black and silver dial with Arabic numerals signed with "Longines" is in perfect condition ( was professionally restored )
Personally I don’t find a problem with someone selling a restored watch, so long as they disclose the restoration as they did here.
Also, I would respectfully object as several of us have discussed in the past, about the notion that “just too clean” means a watch is a redial.
There are many perfect and “just too clean” original watches from the 1940s in existence in private collections.
In this particular case and based on the crisp pictures on the listing itself, the signs of restoration I find significant are:
1/ the font on the “Longines” dial signature is off;
2/ the condition of the dial is inconsistent with the damage (scratches and pitting)’on the case and the movement.
There are more subdued signs which IMHO would not be conclusive in and of themself.
I find the redial job quite nice actually.
