Mister Lambert did a good job of "corpoporate speech diversion" and managed not to answer a tricky question, while not lying at the same time.
Q: Regarding the automatic chronograph calibre some feel and say that the Frederic Piguet company played a role in its conception. What is the truth?
A: I can still certify that there is no Frederic Piguet calibre in any Jaeger-LeCoultre chronograph.
The question was not whether the Jaeger LeCoultre chronograph houses an outsourced calibre produced by Frederic Piguet (which is the question that obviously Mr Lambert actually answers to), but whether the Frederic Piguet company played a role in its conception
A true answer to the question Nicolas rightfully asked would certainly have been very embarrassing to give, since there is absolutely no way to seriously refute that JLC cal is an improved version of the FP 1185 design (a fact that has been acknowledged, but very silently in the past).
This would not at all be a shame to publicly credit the initial movement design (and its designers), since JLC technical team did really bring many significant improvements to it.
This would have even been elegant to pay a tribute where the credit is due, when todays horology world too often keep these information secret.
But failing to tell the truth and playing on words instead is a bit a lack of class I think.
(maintaining that these 2 movement do not share a common base design would be an insult to the reader)
