Astron GPS Solar ‘Super Nova Green’ 5X53 Limited Edition - SSH127J1

Introducing a new design series, marking the 10th anniversary of GPS Solar Astron.

This Seiko Astron GPS watch is a 2023 Limited Edition, featuring our in-house created 5 X Dual-Time Calibre with advanced functionality.

To enhance the speed and quality of the GPS connection, every component in the GPS module has been re-engineered and the operation of the 5X calibre is faster and more intuitive than ever. The functions of this watch allow easy adjustment to Daylight Saving Time and give the wearer the ability to switch the main dial instantly from home to local time when a time zone adjustment is required.

This timepiece expresses the brightness of a spectacular Super Nova through the green gradation dial and radiation pressed pattern with rose-gold dial accents which give a striking style against the black watch case and bracelet. Building on its heritage, the design of this watch also has a modernity, epitomised in its advanced technology within.

Seiko Astron: the world’s first GPS solar watch – powered by light, automatically adjusted to your exact time through the latest GPS technology.
