1417 - Globes & Astronomy - Rare globe clock by L.J. Heymann, Berlin, ca. 1900; the globe is labeled "Earth Globe, 19 cm, revised according to the latest research, Berlin-Zehlendorf, Ludw. Jul. Heymann, Geographical Publishing House,” 12 color lithographed globe segments mounted on a cardboard sphere, the equatorial ring marked with 2 sets of 12-hour divisions. Mounted on a clockwork mechanism in a wooden case, which, by means of a gear-driven transmission, causes the globe to complete one rotation within 24 hours, corresponding to one day. The mechanism runs; fully functional; the globe is slightly browned. Height: approx. 39 cm. Globe diameter: approx. 19 cm.

See description and illustration in: Lehmann, R., Berliner Globenhersteller 1790–1970, 2010, p. 68. - A rare L. J. Heymann clockwork-driven terrestrial globe, Berlin, c. 1900; the terrestrial globe is signed “Erdglobus, 19 Ctm., nach den neuesten Forschungen bearbeitet, Berlin-Zehlendorf, Ludw. Jul. Heymann, Geographischer Verlag," 12 chromolithographed globe gores mounted on a cardboard sphere; the metal equator ring features a 2 x 12-hour scale. The clockwork mechanism, driven by a gear-driven transmission, rotates the globe once every 24 hours, equivalent to one day. Everything is in working order; the globe has browned. Height approx. 39 cm, diameter of the globe approx. 19 cm.
