GPS Watch— Seiko Astron

The Seiko Astron, launched to great fanfare this year, informs time by receiving GPS navigation signals anywhere on the planet. Maybe it was a global-beater within our test? Click the link to see our in-depth review of the Seiko Astron GPS navigation solar watch, with original photographs by Robert Atkinson, first released within our April 2013 problem.


The final time Seiko known as a brand new watch “Astron,” the way forward for timekeeping transformed forever. Released on Christmas Day, 1969, the initial Seiko Astron watch was the world’s first in a commercial sense available quartz watch. At that time, Seiko stated of the Astron, “Someday, all watches is going to be made by doing this.” Today, it’s saying exactly the same factor concerning the new Astron. Is Seiko right? Let’s discover.


Should you haven’t find out about it, the brand new Astron is definitely an analog, solar-powered watch that receives GPS navigation satellite signals and changes towards the precise local time anywhere on the planet. It recognizes all 39 time zones, besting the very best mechanical watches, which could display 37, having a manual totally reset.

The Astron covers the world by first identifying its location using GPS navigation, then evaluating that information by having an onboard database that divides the Earth’s surface into a million squares, because both versions is designated to particular time zone. That’s something not one other watch can perform.


The Seiko Astron is different from watches that receive terrestrial radio signals from atomic clocks. So-known as RC (radio-controlled) watches receive signals when they’re within selection of stations within the United States, Japan, the United Kingdom, Germany and China, so they don’t offer global coverage. The Astron works anywhere, even in the center of a sea or desert, in Antarctica, or on the Tibetan mountaintop. Seiko Astron watches also instantly recognizes which time zone they’re in, while RC watches don’t.

The Astron also is different from Citizen’s limited-edition Satellite Wave, which receives GPS navigation signals, but lacks a GPS navigation geo-location function so it doesn’t change time zones instantly. Finally, although the Astron is really a GPS navigation receiver discussion precisely where it’s, it can’t lead you to that particular new restaurant downtown, or let you know what lengths it’s towards the 14th green. It uses GPS navigation exclusively to inform time.
