GPS Solar

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.

Dynamic movement of the hands, which can sense the connection with satellites

When GPS signals are received, the second hand starts moving, indicates the number of satellites, and then displays the current time.
It is an emotional moment, feeling an identification with GPS satellites 20000km away.

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.
