Extending the legacy of the Seiko Astron, the world’s first commercially available quartz watch, today’s Astron is designed for a new generation of leaders to break through to a new future with excellence in both innovation and style. Strong and distinctive, with its perfectly sculpted octagonal titanium bezel, this dynamic timepiece combines solid tailoring with the highest degree of accuracy possible in a wristwatch.
