I spent more than a decade making and repairing industrial clocks. One of
the quickest way for anyone to wreck them was to oil the bronze motor
bearings.


Indeed. Those are very low torque low ROPM bearings indeed, and must be
run
essntially dry.

The same is NOT true of motor bearings, which are high RPM and medium
torque. These must NOT be run dry.

You are thinking of the wrong type of clock. The ones I made were industrial
timers, based on synchronous motors.
