Mercantile National Bank Building - Tower Clock

Tower Clock

The clock tower and 115-foot (35 m)-tall ornamental spire is a local landmark and reference point in downtown Dallas. There are (4) 20 ft (9.4meter) diameter tower clocks. New tower clock movements and hands were manufactured in 2007 by Electric Time Company. The Clock hands are lighted with LEDs which replaced the original neon. Above the clock a series of LED (originally neon) lights display weather information. White light rings flash upward when temperatures will rise and downward when they fall. A star-shaped light at the spire's top glows green when weather forecast is fair and red when it's inclement.
