WATCH POP

I noticed that every movement of Lange engraved with "Made in Germany" except Perpetual movement. Does it mean that the Perpetual movement has used some parts that not made in Germany?
Just wonder. Here's a pic once posted by Mike Margolis (I hope he doesn't mind):


You can just barely see the "MADE IN GERMANY" along the bottom-left edge of the rotor "runner", on the plate adjacent to the case edge. It's much more visible in person, even with the naked eye. I believe all Langematiks use this location (including my perpetual).
I'm not sure where else Lange's movements would be made. No Poljet rumors yet. ;)
Cheers,
Ken. sorry, I'm wrong.
