There ARE differences between the JLC and the FP (improvements, finishing, wheels moving fourth wheel from front to bottom), but otherwise I maintain that base design is the same.
I tried my best, with the available material, to put the 2 movement side by side.
But the FP picture is actually the picture of a partially disassembled movement (without rotor), and so is the JLC, and some parts have been removed from the JLC (minute wheel) that are still in place in the FP.
There are just too many coinciding holes, wheels, gears and gears positioning that it is just not possible that someone who would design a functionnaly similar chronograph from scratch could have come up with such a similar layout (to the exact smae dimensions) purely by luck.
But people seem to play on words, saying that the 2 movements are different (they are) while I only want to point that they use the same ebauche design.
An analogy could be the Hublot version of the 7750. It is made by Hublot, not by Valjoux, but still it is a Valjoux design.
Or, if you want to stay in higher horology:
Here, I see a very nice movement by a great name, but still the base design is a Valjoux 23
I am an engineer, and I can tell you that it is not possible to create 2 so similar movements (FP and JLC) by coincidence. No way
