The Classic Mechanical World Clock That Maps Time Itself

The Original Kilburg Geochron is the most iconic mechanical world timepiece ever created—an elegant wall-mounted map that simultaneously tracks time, daylight, and Earth’s rotation with extraordinary precision. Since its invention, it has become the gold standard for professionals, institutions, and collectors who demand a tangible, real-time understanding of global time zones.

Beneath its clean white panel lies a marvel of engineering: a continuously moving world map driven by a precision electric motor, perfectly synced with the Earth’s rotation.


🕰️ What the Geochron Displays — All in Real Time:

🌐 Time & Geography Data Displayed

✅ Local Apparent Time
✅ Greenwich Mean Time

✅ Sunrise and Sunset Lines

Each time zone is clearly marked and corresponds with a lettered index at the top of the map, matching standard time zones and international shortwave radio prefixes.


🗺️ Mapset: Topographical

This version features the Topographical Mapset, presenting the Earth’s natural terrain in rich detail—mountain ranges, rivers, plateaus, deserts, and ocean depths—ideal for those who prefer a physical geography perspective.
