Astron GPS Solar celebrates the 50th anniversary of the Quartz Astron

Today, 50 years after the Seiko Quartz Astron ushered in the quartz revolution, the enduring popularity, ubiquity and versatility of this remarkable technology have all been proven beyond any expectation. The Quartz Astron changed the way the world told time, astonishing people with its accuracy of +5 to -5 seconds per month. It also shaped the whole future of the electronics industry as several of its inventions, including the tuning fork shaped quartz oscillator, are still used in an extraordinary range of horological and non-horological devices alike, from clocks to personal computers to mobile phones. It is no exaggeration to say that, since 1969, Seiko’s quartz technology has touched the lives of nearly all mankind and continues to play a central role in our ever-changing modern world.

Now, a new Astron GPS Solar 5X series pays homage to the uniqueness of the first Quartz Astron of 50 years ago in both its design and in its technological advancement.

The GPS Solar 5X caliber. A technological achievement that adds new luster to the celebrated name Astron.

Since its launch seven years ago, Astron GPS Solar has taken the art of electronic watchmaking to new heights. With its accuracy of one second every 100,000 years, its ability to connect to the GPS network using just the power of light and its automatic adjustment to every time zone* on earth, Astron GPS Solar has found great favor with international travelers and lovers of high precision watchmaking alike.
