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.

A remarkable 1735 Zacharias Landteck and J. B. Homman diagram of a 'universal clock,' with instructions in German (left) and Dutch (right) on how to use it to determine the time and thus longitude at sea - an age-old problem for mariners. This advertising piece for Landteck's clock, known as Geographische Universal Zeig und SchlagUhr an (Universal Pointing and Chiming Clock), was published in 1735, not by chance, for this was the same year that Englishman John Harrison claimed the Royal 'Longitude Act' prize for his own groundbreaking invention, the marine chronometer.
