[time-nuts] Re: Crazy Clock

[Roger Brinkman]

Hi Bob,

Seiko Corporation has produced a range of GPS receiving clocks under its “Space Link” name for several years. They have also a produced a range of GPS synchronised quartz wristwatches under their “Astron” name for more than ten years.

See www.seiko-clock.co.jp/product-personal/wall_clock/satellite/

And Silicon Chip Magazine, a fantastic Australian electronics hobby magazine, has published several GPS time projects over the past 7 years or so. Their most recent project in September details modifying a regular quartz clock to use a GPS receiver. You can find a preview of that project and purchase a kit of the parts at:

Hope these help you find what you’re looking for. 

Roger.
