Seiko: Astron Solar

Even before the Seiko Astron was for sale in stores, this watch turned out to be a huge success. Logical, because with the Astron, Seiko has managed to build a number of unique functions into a watch. This success was also clearly visible with us, the ten Astrons that we received in the past year were usually sold before they were actually in the store. Today there is hardly any Seiko Astron in the Netherlands anymore.

Except with Brunott. Two weeks ago we managed to get hold of two more of these beautiful watches. And you can be sure, they are not the least of two. Although a Seiko Astron in itself is something very special to wear on your wrist, the Limited Edition that is now in our store certainly is! If you have been looking for this fantastic timepiece for a while, be quick because we only have two.

Technical specifications:

Spring 2012 SEIKO introduced the world's first analog GPS watch: the SEIKO Astron GPS Solar (named after the world's first quartz watch from 1969). The Astron GPS Solar recognizes all 39 official time zones on Earth and can therefore always display the exact local time. The spectacular watch has a micro-GPS receiver that consumes so little energy that all functions can function optimally on Seiko Solar technology. Is the SEIKO Astron GPS Solar - equipped with 100 patented inventions - the most intelligent watch ever built? The following specifications generally apply to the Seiko Astron:
