JLC has only the JLC archives, not the Lecoultre archives which were lost.

So, JLC will only provide informations on the prod year, the reference. It is by not mean a certificate of authenticity. But an extract of the archives. Not the same.
That being said, I had a privileged contact at the Heritage Gallery, which allowed me to get some very interesting informations and documents to write my reviews on some vintage JLCs.
Best,

Has anyone ever seen a black dial E329?

This is my first post on the forum. Thanks so much for keeping it up. I have seen the attached dial, presented as an E329. But I have never seen a black E329. Thanks!...

Nor do I... [nt]

Do you think the watch might be legit? Or do you think it\'s redialled? Do you have any sources of information to recommend?

“Good news for the client. The piece is in his original state, it is a LeCoultre model produced in the Manufacture for the US market”

Great news, indeed. Bravo for this piece. First time I see one. I know the reference, I even owned a SS one. But JLC version. [nt]

I am 100% certain the dial is wrong

Although JLC 'might' have confirmed authenticity (how? by looking at the watch in person? and, more importantly, who, and did they provide a certificate?), I am totally certain this dial is a repaint. While one can argue that the watch is indeed authentic...

Thanks for the advice

However, I really like the way it looks, so will keep looking around for some information or documentation. Please keep me in mind in case anything pops up.

Interesting question/ debate

I recall having a discussion with a good friend about the "Heritage Department" of JLC. Can you please, Clavi and Amanico, elaborate about it? I know that Patek Philippe have a strong team. I know that Longines have a 6 members strong team, a museum curat...
