Craftsmanship

A handmade, precision-engineered masterpiece

The Geochron is the only mechanical chronometer to simultaneously display the current time and the sun’s Event Horizon simultaneously, anywhere in the world.

The world map is made using a high resolution lithography process, which incorporates environmentally-friendly UV-Curable inks rendering the maps resistant to ultraviolet light and scratching.  Machined components are fabricated on CNC and screw machines to exacting tolerances.

Building on the original design of the first Geochron over 50 years ago, we’ve improved on its appearance and internal design:

 

 

  • 2005 – Most mapsets are now printed on digital offset, which has a higher resolution and color consistency than screen printed mapsets.
  • 2012 – Major redesign of the internal Map Motor plate.
  • 2012 – Thicker and better quality plastics for the moving shadows, which create the the Sunrise-Sunset line on the clock.
  • 2015 – An LED lighting system replaces the fluorescent lighting on most clocks.  LED Lighting uses less energy, and improves the color spectrum of the map.  (read: it looks better)
  • 2015 – Introducing a new Topographical Mapset.
  • 2016 – Introducing a new Ham Radio Mapset.
  • 2016 – The drivetrain of the Geochron is completely redesigned for durability and accuracy.  With Dura Drive technology, we’ve engineered the most reliable Geochron ever made.
  • 2016 – Introducing the Sunlit Analemma, showing glowing yellow “sun” to indicate the position of the sun at high noon between the Tropic of Cancer and Capricorn.
  • 2017 – Introducing Dimmable LED Lighting with remote control.

But even after more than 50 years, the Geochron is still assembled by hand in Portland, Oregon.  It takes our four clockmakers (as of 04/2016) three days to build a clock, then a “burn-in” on the test wall.  Each Geochron passes through multiple quality inspection checks along the assembly process, including a rigorous 28 point inspection over two days prior to shipping.

And it is with insistence and a sense of pride that the Geochron remains the only mechanical geographic chronometer made on Earth.  300 pieces, all fabricated and assembled by hand.
