Landteck, Zacharias


Zacharias Landteck (1670 - 1740) was a clock- and watchmaker based in Nuremberg (Nürnberg), Germany. In 1705, he produced, either alone or in collaboration with J. B. Homann (1664 - 1724), a 'Universal Clock,' the Geographische Universal Zeig und SchlagUhr an, intended to assist in navigation by enabling mariners to determine the time at sea along any meridian.
