SEIKO ASTRON

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.

Feature

1. At last, a watch that adjusts to your time zone.

Astron is a world's first.

It recognizes all the currently recognized 39 time zones on earth.

2. The hands adjust automatically
 to the local.

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.

3. Always accurate.

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.

4. Astron Never stops.

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.

5. Astron receives the time signal
 even on the move.

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.

6. Calendar correction is automatic.

Astron has a Perpetual Calendar that is correct until February 28, 2100.

* The watch has to be under an open sky with good visibility, where the GPS signals can easily be received.    * Each time zone is based on data as of January 2012. However, changes in time zones thereafter are not included in the data.    * If the time zone is adjusted near a time zone boundary, the time of the adjacent time zone may be displayed. To adjust the time zone, use the manual time (city) zone selection mode.

Design

Astron is a watch that unites time
and space as never before, and whose
design reflects the grandeur of this
technical achievement.

Look into the dial and you see both the
darkness and the depth of space,
while the silver and gold indexes shine
like stars and the ceramic bezel gleams
like a satellite orbiting the Earth.
