A Revolution in Time
The Seiko Quartz Astron changed watchmaking forever. Released in 1969, it introduced unprecedented quartz accuracy and marked the beginning of a new era in timekeeping.
Precision Without Borders
In 2012, Astron revolutionized timekeeping once again. The world's first GPS Solar watch combined satellite technology with solar power to deliver extraordinary precision anywhere on Earth.
The second generation Seiko Astron is a GPS solar wristwatch that was released in 2012. While the new Astron had functions and capabilities that far exceeded those of its 1969 predecessor, the name Astron was chosen to demonstrate the importance of the GPS Solar technology that it contained and to highlight the high accuracy which was just as revolutionary as that of the first Quartz Astron.
With a new strong and distinctive case shape, the latest Astron introduction features a perfectly sculpted octagonal titanium bezel, combining solid tailoring with the highest degree of accuracy possible in a wristwatch. Powered by Seiko’s new GPS solar caliber 3X62, with the improved receiver sensitivity required by the metallic bezel, this exceptional design offers time zone adjustment to 39 time zones, a multi-function indicator subdial for easy mode reference, and highly visible three-dimensional applied indices on the pressed pattern dial.
