That?s a nice one, but....
... discontinued.
If i recall correctly, it came with a Valjoux 7750 base.
The only cambered cushion case chronograph (hey, let?s call it "quadruple C"
) is reference 24980 of the Classique Elegance line:

It?s not a rattrapante and comes with a movement based on the ETA 2892A2. That?s an attractive piece, an unusual case shape and a very nice dial in black or white. Some specs in our
Virtual GP Gallery.
And if you like it, i?ll see if i can throw in some pictures.
Greetings,
Peter
