Jesus, $20k just for the insert... :shok:
Bananas. And I thought 1675 inserts were expensive... I wonder how rare these radium bakelites really are?
Looks like Rolex used Radium until 1960, and the 6542 was produced until 1959 (if google isn't lying to me), so all original bakelite inserts should be radium based, as fragile as they are.
