Hi mech,
You Lemania powered PP is not a 5004 has your watch has only 24 jewels.
I don't think it is a 3970 or 5020 either as the finish of the calibre is really top and such finish is more recent than the introduction of the current generation of manual wind chronographs. I'm talking of the work on the closed angles!
So it is either a 5070, a 5071, a 5970 or a 5971!
Looking at your pic only I doubt we could be sure of any answer. 
You don't own only white metal watches and seemed recently to like pink.
That would not seem stupid to wait a white metal watch (5970P) with a watch of another colour.
So If I had to guess I'd say a 5070R!
Can't wait to see your 5970P though!

Cheers
Dje
