The new Astron GPS Solar World-Time.
Less is more

The new Astron world time caliber delivers all the advantages of GPS solar in a design whose dial is as simple as it is refined.
Caliber 8X22 broadens the appeal of Astron still further, offering a slimmer case and a clean, uncluttered dial layout which allows the world traveler to see local time at a glance.
The dial of the new world time watch is simple, with all the indicators in one small sub-dial, giving the watch a quiet, refined elegance. The Astron GPS Solar world time offers everything essential and nothing else. Truly, less is more.

Slim, elegant and understated

Caliber 8X22 is a notable advance in Seiko’s GPS Solar technology. The case is slimmer than any other GPS Solar watch1, even slimmer than all other Astron models (the depth is just 12.4mm compared to 13.3mm in the other 8X series). As a result, the antenna that receives the GPS signals is inevitably smaller, but Seiko has managed to increase the processing power of the circuit in the GPS module so that the sensitivity of the antenna is unchanged and the reception of GPS signals is as easy for the world traveller as ever.

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.
