The Astron revolution continues apace with the addition of a third caliber, designed specifically for the global traveller. Using just the power of light, Astron connects to the GPS network and tells time with atomic clock precision, adjusting at the touch of a button to your time zone. Now, with the Dual-Time caliber, you can read not only the time where you are, but also the time in your home time zone.
With the new Dual-Time caliber, you can read not only the time where you are, but also the time in your home time zone on a simple 12 hour sub dial, a new feature for Astron.
Dual time with AM/PM indication, day and date.
Everything the global traveler needs.
Metal indexes adopted to complement the hands are finished separately to provide enhanced metallic texture and luxuriousness.
The operation of the watch is made simple by the electronic setting function in the crown.
Wide and strong hands greatly increase visibility.
The cases are polished by hand to be distortion-free, using Seiko’s unique Zaratsu technique, so that there is sharpness in every light reflection.
The bracelets are composed of individually designed links and are therefore tapered perfectly to the wrist for maximum comfort, however and wherever you may travel.
Thanks to the creation of an ultra-low consumption GPS module, Seiko has been able to create a watch that can receive GPS signals and identify time zone, time and date using the global network of GPS satellites.
Astron is entirely self-sustaining and takes all the power it needs just from light. There is no need, ever, to change a battery.
Radio control watches
GPS Solar watch
Unlike radio control watches, which work only in a small part of the world's land mass, GPS solar watch identifies the recognized time zones on earth. Whether you are on a mountain top, in the middle of the ocean, or even in the center of a desert, the watch displays the exact local time.
※For the time zone information of caliber 8X53, please refer here. If there are changes in the region/time zone, manual time zone selection may be required.
In order to avoid any interference with the operation of electronic devices in an airplane, in-flight mode is available when boarding a plane. In the in-flight mode, the GPS signal reception function will not work.
In areas where DST (Daylight Saving Time) applies, the time can be adjusted manually.
