The Colgate Clock is an octagonal clock in Jersey City, New Jersey, United States, with a diameter of 50 feet (15.24 meter), and it faces the Hudson River. It is currently situated 400 meters south of the former site of the headquarters of consumer products conglomerate Colgate-Palmolive, which was until the 1980s based in Jersey City.
The current Colgate Clock was built in 1924 to replace an earlier clock designed by Colgate engineer Warren Day and constructed by the Seth Thomas Clock Company for the centennial of the Colgate Company in 1906. The original clock was relocated to a Colgate factory in Clarksville, Indiana.
As of 2005, the Colgate Clock stands on an otherwise empty lot; all of the other old buildings in the complex were demolished in 1985, when Colgate left New Jersey. The lot is located on the Hudson River waterfront and the clock itself is 100 meters south of the Goldman Sachs Tower, the largest skyscraper in the state of New Jersey. The construction of that building in the early 2000s forced a relocation of the clock southward to its current location. At the time of the relocation the size of the Colgate advertisement attached to it was reducted to comply with the Hudson River No Billboard law. As a part of the relocation agreement Goldman Sachs now maintains the clock.
