The unspeakable (S.F. Foudroyante) and the split second chronograph
Howdy folks,
a question raised several times is regarding the movement of these watches.
The information is was given so far (we are on the track of some detailed information):
The S.F. calibre GP 8298 as well as the rattrapante calibre 8290 both are based on a Valjoux 7750 base, highly modified with exclusive changes by GP.
Ok, before someone gets the wrong idea some standard base ebauche will pop out of the case:
The Valjoux 7750 certainly is one of the best automatic chronographs movements. It was introduced in 1972 (if i recall correctly) and constructed by no other than Edmond Capt (former technical director of Frederic Piguet and Nouvelle Lemania) who some regard as one of the 20 best watchmakers alive. It?s a very well designed, there?s hardly anything to improve. Therefore it?s a perfect base even for highly (or Grande) complicated watches.
And what GP does with it to, simply results in a new movement.
Don?t believe in this?
Ok, here?s the plate for the 8020 chronograph movement:

That one really doesn?t look very ETA, isn?t it?
