He has had two 9020βs and both also had problems with Foudroyante hand as well.
He said when his watch maker opened it up, it was the Foudroyante wheel had had cracked. Itβs made out of aluminium and he is not sure if it was damaged because of excessive wear or if a previous watchmaker had damaged it.
