A new, luxurious, sapphire crystal bezel

The new bezel uses sapphire crystal for the first time for Astron, which gives the watch a luxurious and transparent feel.

A unique design for the case and bracelet

The case and bracelet with sharp surfaces creates the feel of quality.

Clean-cut dial

The well-defined dial is the signature of Astron, and longer hands and markers increase legibility.

Luxurious feel. Beauty. Comfort.

Seiko’s technology and leading craftsmanship are consisted in the Astron Executive Line.


Stylish and luxury markers

Metal markers adopted to complement the hands are finished separately to provide enhanced metallic texture and luxuriousness.

Zaratsu technique

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.

Intuitive operation

The operation of the watch is made simple by the electronic setting function in the crown.

Comfortable to wear

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.

GPS Solar

The world’s first GPS solar watch

By connecting to the GPS network, the new Astron adjusts at the touch of a button to your time zone* and, by taking all the energy it needs from light alone, never needs a battery change.

  • For the time zone information of your caliber, please refer to here. If there are changes in the region/time zone, manual time zone selection may be required.

Automatic time adjustment

Whenever the dial is exposed to bright light, the watch automatically receives GPS signals. When the watch is concealed under a sleeve and the dial cannot receive enough light, the watch stores the time of the previous successful manual time adjustment or time zone adjustment, and automatically starts time adjustment at the same time.

High reception performance of an exclusive Seiko ring antenna

An exclusive Seiko ring antenna placed under the dial ring is suitable for automatic reception as it can easily receive signals regardless of posture.

In-flight mode

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.

DST (Daylight Saving Time)

In areas where DST (Daylight Saving Time) applies, the time can be adjusted manually.
