coroner's office said many of the watches found in
the Iroquois Theater auditorium after the fire had
stopped working at 3:50 pm, the time the fireball
went hurling from the stage out into the audience.
Presumably the heat of the
fireball melted the clockworks enough to interfere
with operation. 1,700° F would have created a puddle
of brass and glass so it was something below that.
