Mystery Le Jour Chrono . . .

Does anyone recognize this model? Considering adding it to my growing collection of Yema/Le Jours, but this one is totally new to me . . .

You might be right. Then again, lume on hands ages differently than lume on the dial. Also, I'm not one to turn my nose up at relumed hands, as long as it was done professionally!

It's very similar to this Guymo, which is another Swiss-cased, French-dialled watch from the early 70s. https://www.timeline.watch/watch/guymo-chronograph/

The little "pin" at the end of the minute hand stops just shy of the seconds hashes, the squared off white hour and minute hands are matched by the squared off white hand on the seconds subdial, and the orange chrono is matched by the orange hand on the minutes subseconds dial. So I'm thinking the hands are original, but quite possibly relumed.

Moot point now in any case, since it already sold, so someone must have liked it!
