The clock, created by John Flanagan (1865-1952), is constructed of a variety of brilliantly colored precious marbles against a mosaic background encircled by the signs of the zodiac in bronze. Above the clock a life-size figure of Father Time, executed in bronze, strides forward with scythe in hand.
To the left and right are the figures of maidens with children representing the seasons. The dial of the clock is approximately four feet in diameter and in the center is a gilt glory, or sunburst. The hands of the clock, which are also gilded, are jeweled with semiprecious stones.
