A Modern Geochron in Glittering 4k Resolution

The Geochron Digital 4k UHD gives viewers beautiful displays of the Earth with the sunrise-sunset rendered in real-time through a small computer that plugs directly in to your TV via HDMI.  The size of your display is only limited by the size of your TV, as you take in the terrestrial movement of the Earth’s orbit in sync with the Sun.

The Geochron Digital 4k UHD displays a full-featured Geochron World Clock on any 4k TV, with every mapset and lighting option available in our famous mechanical clock but at a fraction of the cost. Now in the digital format, users customize markers on the map, and receive (with internet) real time updates.

  • Lifetime updates for five mapsets.  Live location of the International Space Station and over 100 satellites, updated every 15 seconds.*
  • High Speed demonstration mode. One year in 15 seconds!
  • Sixteen Locations Pins with custom text names and local time that you can place anywhere on the map.
  • Static Overlays, showing:
  • Digital Time Accuracy to within 500 milliseconds*, and on-the-fly time adjustments to local time zones.
  • Automatic Night Dimming by your location.*

* with internet connection

Multiple Views on the World in Real Time

With our easy-to-use on-screen menu, this Geochron has every mapset available: Earth Human, Earth Oceanic,  Earth Topographical, a simple low resolution Geopolitical, and Ham Radio. Every map can be layered with humanity’s lights in the night, as seen from space.

Watch the sun rise over special locations, and mark them with customizable location pins. See the human expanse over the continents with lights reaching into the night.
