In 1969, Seiko Quartz Astron, the world's first quartz watch was launched.
It was accurate to within 5 seconds per month,100 times more accurate than any other watch, and its low-drain movement allowed it to run continuously for a year, or 250 times longer than most mechanical watches.
Seiko Quartz Astron was a revolutionary wristwatch that changed timekeeping forever.
Today, the new Astron delivers another breakthrough in watch technology – a quartz watch with accuracy of one second every 100,000 years and time zone adjustment.
Astron is a world's first.
It recognizes all the currently recognized 39 time zones on earth.
With only one touch of a button, Astron adjusts to the correct local time everywhere on the planet. * Daylight Saving Time function requires manual operation.
Seiko Astron is accurate to one second every 100,000 years, thanks to the time signal it receives from the Atomic Clocks in each GPS satellite.
Astron receives all the power it needs from light absorbed through the dial. It uses all kinds of light and there is a power reserve indicator to show the amount of energy stored.
Astron receives GPS signals even when the wearer is walking or in a vehicle. If you can see the sky, you can tell the exact local time, even on the move.
Astron has a Perpetual Calendar that is correct until February 28, 2100.
