How to make a grandfather clock tick faster. If you remove the escapement the watch will just motor the hands around a fast rate until the main spring unwinds.

Conversely for most grandfather clock movements if one turns the screw beneath the pendulum bob counter clockwise or left to lower the pendulum make it will make the clock go slower.
To speed the grandfather clock up move the pendulum disk up by turning the adjustment nut to the right. This is adjusted by turning the nut at the bottom of the pendulum. Pocket full of time 72 201 views. What is the maximum speedup you can roughly obtain on a regular quartz wall clock.
