LARGEST and most accurate sandglass of the world - Superlatives on Waymarking.com

The sandglass was made founded by the Schott Glaswerke (visit link) to the city of Mainz.

The special glass cylinders turn around every hour controled by a microprocessor. The processor receives the dcf77 signal from the radio clock transmitter in Braunschweig (about 300 km north).

Nearby, you can found the Museum of Natural History of Mainz.
