Since the movement base is a A7750, the complete movement has inverted position in PT and in KW version
You will get SWISS MADE but in another different position or inverted.
But not only SWISS MADE, all the inscriptions will be different !!
What flaw do you prefer ??
Up to you
It is no missing. This is not KW version, it is a different movement from anothe maker
PT version has not escapement wheel, and has different Incabloc bridge (balance cock) decoration !
