The watch has some flaws, I don't know about the lume, as it's really hard to compare on pics with different lightning, camera setup, adn so on...
This PAM518 is a really nice watch, amazingly well finished, all details (even if "flaws") had many attention.
As the gen is limited to 50ex, I don't think that someone will point out the lume, even movement. Most of the ppl don't know Panerai, and the ones I saw with one, mainly, when you ask them, they reply "It's a Luminor" or "Luminor Marina"... they don't know the refs, models, so about lume or movement... they buy what they see at the AD.
I could never afford the gen, so if someone knows enough Panerai and this model, he'll know that couldn't be a gen... No need to have a look to the watch...
Once ordred I tought i made a "mistake", not a good rep, movement, and so... believe it or not, this PAM518 didn't leave my wirst since 3 days now !
