Seiko introduces the new 5X GPS Solar caliber. The world's most advanced GPS Solar caliber ever. The new Astron GPS Solar is faster, even easier to operate and offers better reception options. The energy consumption has also been optimised.

The Seiko 5X53 caliber is the prestigious analog GPS Solar DualTime caliber. With a simple push of a button, this watch can set itself to the correct time zone from anywhere in the world, and thus display the correct local time. On the dial, the GPS signal indicator shows whether the watch is connecting to the global GPS network. The watch also shows how many satellites the watch connects to. To determine the correct time zone, a connection is required with at least 4 satellites. When the watch is fully charged, the watch makes satellite connections with one satellite up to 2x a day to correct the time. This makes the 5X53 GPS Solar watch extremely accurate and the watch only has a deviation of 1 second per 100,000 years. If necessary, the local time can also be changed manually.

The smart Perpetual Calendar function ensures that the watch always shows the correct date up to the year 2100. The watch has an in-flight mode, the daylight saving time can be adjusted automatically and a second time can be set. The second time is displayed in a 12h window with a separate AM/PM indicator. With the TimeTransfer function, the display of the two times can be switched with a simple operation.

The built-in watch micro-GPS receiver consumes so little energy that all functions function optimally on light energy generated by the Solar dial.
