There are four clock faces in the tower — one each looking north, east, south and west.
After Brasky cuts the power (or “stops the escapement,” for those fluent in clockspeak) he must crank forward each minute hand individually.
After manually moving the giant metal pointers, Brasky will take a quick walk around the outside of the building, checking that the time on each clock is exactly right.
But before 1947, Deroshers said, the City Hall clocks operated on a pneumatic system, meaning they were powered by air — which is much harder to control, and even tougher to set forward and back with accuracy.
But the work Brasky does to make sure the City Hall clocks display correctly is still useful, Deroshers said.
