Phil has two favorite escapements. Grasshoppers are first on his list by virtue of their geometry and animation. A close second is the Gravity escapement as used in Insionn (Gaelic: Mechanical time telling device)

Typically these types of escapements are used in very large tower clocks.  Tower clocks need a significant amount of power to turn large hands and deal with weather conditions. If that same power were allowed to impulse the pendulum, it would adversely affect its timekeeping properties. The gravity escapement is arranged in such a way that this excessive power is used only to reset arms either side of the pendulum. When the arms are released by the escapement, they impulse the pendulum and keep it in motion. This arrangement was invented by Edmund Beckett Dennison (Baron Grimthorpe) around 1850 and used in his design of the clock at Westminster (Big Ben). 

The action of the escapement and the resetting of the arms are fluid and large enough to appreciate visually. In Insionn, Phil deviated from the typical pattern of the Gravity escapement by arranging the arms upside down. He also slowed down the action of the escapement with large peacock feathers and a slow beating pendulum.
