Just some quick notes:
It's a modified A7750
A lot has been modified (correctly):
-Balance bridge completely re-designed (no mock up)
-Main spring click totally new (gives a gen feel)
-New Mainspring with bridle stop to prevent slippage
-Top plate redesigned to take te new click and movement decoration.
All I can say is that the movement is very stable and reliable. And with the cover it is very very accurate. I believe Alle calls it the most accurate Radiomir up to date in his Panerai 'bible'.
