Official description

Astron GPS Solar remains unsurpassed in its precision and utility as the watch for the interna- tional traveler. Thanks to its unique, high-efficiency GPS module, it connects to the GPS network and adjusts, with atomic clock precision, to every time zone* at the touch of a button, while taking all the energy it needs from light alone. Over the past decade, Astron’s GPS technology has been refined and its functionality enhanced such that the latest genera- tion, featuring Caliber 5X53 Dual-Time, offers the ultimate in precision, energy efficiency and ease of use for those who demand the very best in high technology watchmaking.

Now, Seiko Astron adds four new watches with a design that is as cutting edge as the GPS Solar technology they contain. The cases are all in titanium and have a sharp, angular construc- tion that is as contemporary as it is refined.

This new series includes three watches with dials in silver, blue-gray, and black and a limited edition watch with a unique striped dial. The three watches will join the main Astron collection and will be available at the Seiko Boutiques and selected retail stores worldwide from July 2022. The limited edition watch will be available from May.
