This is the huge digital clock at the south end of the building at 200 Water Street photographed on February 21, 2010 at 5:26:55 PM. The 45-by-50-foot digital clock was created by artist Rudolph de Harak. While the numbers may appear to adorn the exterior of 135 John Street, the display clock actually belongs to the adjacent 200 Water Street, a 32-story building designed by the architecture firm of Emory Roth & Sons and completed in 1971. The device consists of 72 square sections, each containing a number from 00 to 59. Once lit to display the accurate time hour, minute, and second, the clock has lost time over the years but remains a Lower Manhattan landmark. In 1998, 200 Water was converted into a 576-unit residence hall and is now home to New York University undergraduates. Although NYU holds the lease on 200 Water Street, building owner Rockrose Development is responsible for maintaining the clock.
