For over 50 years, it’s still striking – and featured in the White House Situation Room, NASA, 135 installations in the Pentagon, and – of course – thousands of ham shacks worldwide.    No computers, no circuit boards, and true to its original design, the Geochron is – and always will be – a mechanical master piece of 300 moving parts to create the finest global clock in the world handmade in Portland, Oregon.

Handmade in Portland, Oregon, take a minute to read about the precision craftsmanship that goes into each and every Geochron, and how it could be the centerpiece to your ham layout.

(Insider’s Tip: Most of the Geochron’s we’ve made for Ham radio operators are the Standard Model, our most affordable clock.  It’s not listed on our general website, but we do make them.  You can find Geochron Standard here.  Check the top of the page for other options.)
