digital clock building - 200 water street

this is my favorite building facade in nyc. it's at 200 water street, and apparently it is a clock, but i've never seen it tell the correct time. i was absolutely shocked the first time i saw it looming discreetly as i walked to the south street seaport, its numbers flickering and immediately drawing me in. it makes me infinitely happy that little - er - big treasures like this exist in the world.

here's my snapshot:

here's an evening photo i found on the nyclovesnyc blog:

along with the image, this information about the building is noted:

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. 

i also read somewhere that it was the largest digital clock in the world for quite some time. the history of the entire development, which is interesting, to say the least, can be read here. let me just mention, the original design included an entrance through a large, corrugated steel neon-lit tunnel. very futuristic.
