Great Gravity Clock


The Great Gravity Clock stands fifty-two feet tall and is the biggest kinetic energy sculpture in Florida. Located in the Museum’s Grand Atrium since 1993, this unique timepiece is one of the only three that exist in the world.  The other two are in Mexico and Japan.  More than twenty-five years ago, Jim and Jan Moran and JM Family Enterprises partnered together to bring the Great Gravity Clock to Broward County. Years of exposure to the elements compromised its ability to tell time so a major restoration was undertaken in late 2016.  JM Family Enterprises, Inc. and The Jim Moran Foundation generously funded a complete restoration of the clock, which was completed in early April 2017.  Now a new generation of museum visitors can enjoy telling time with the Great Gravity Clock.
