Astron was the name of the first quartz wristwatch, which Seiko put on sale in 1969. Since 2012 the name belongs to Seiko's GPS Solar watches: they are powered by light and set the time and time zone from GPS satellites at the press of a button.
Models differ in what they show beside the time: a second time zone, a chronograph or a world-time ring. Titanium cases are common and make the larger sizes light to wear; the case material is in the specifications.
We stock 49 Seiko Astron watches, from $790 to $3,430.
