Seiko Astron GPS Solar Dual-Time 5X53

A brand new Caliber 5X powers the brand's most advanced Astron GPS Solar collection.

Since its first appearance in 2012, Astron has proven to be a success worldwide. In its six years of existence, hundreds of thousands of Seiko lovers and world travellers have found the practical, ‘’real life’’ advantages of Seiko’s GPS Solar technology and the Astron design to be an irresistible combination. Over the same period, the range of Seiko’s GPS Solar calibers has advanced and expanded such that Astron now offers Chronograph, Dual-Time, World-Time and Big-Date versions. 

Today, a new chapter in the history of Astron GPS Solar technology opens with the launch of an entirely new caliber, 5X, that offers the most advanced functionality ever. The new Astron 5X series is the world’s smallest and thinnest* GPS solar watch. It is just 42.9mm in diameter and 12.2mm in depth.

*As of August 1, 2018. Based on Seiko’s research. All versions except SSH009/011, which are 43.5mm in diameter and 13.3mm in depth.

Increased functionality for the world traveler 

To enhance the speed and quality of the GPS connection, every component in the GPS module has been re-engineered. The operation of the 5X caliber is also faster and more intuitive. For example, only three seconds are needed to advance 14 hours from Tokyo to New York time, thanks to the system that moves hour, minute, and seconds hand independently. New functions also allow automatic adjustment to Daylight Saving Time and give the wearer the ability to switch the main dial instantly from home to local time and vice versa.

Its comfort on the wrist is further enhanced by a new buckle system that the wearer can use to make the minor adjustments that are so important when temperature or other changes make the wrist expand or contract. 

Like all its predecessors, the new Astron 5X series adjusts at the touch of a button to your time zone* by connecting to the GPS satellite network and, as it takes all the energy it needs from light alone, it never needs a battery change and yet delivers the precision of an atomic clock, one second every 100,000 years. It even connects twice a day to the satellite network; the first connection is made after the dial sensor detects sunlight and the second is made at a time pre-determined and set by the owner. It is the perfect timepiece for the global traveller. 

* If there are changes in the region / time zone, manual time zone selection may be required.
