Thank you for your thoughts.

The free sprung balance also isolates critical parts when others are less than perfect...

So, an argument could be made (or a theory postulated) that a Rolex movement could continue to keep admirable time even if some parts are on the point of failure; whereas, the 2892-2 could/would show poor cadence much sooner.....
