The Seiko Astron GPS Solar Titanium Collection blends advanced technology and refined design, catering to modern leaders who value innovation and aesthetics. Building on the legacy of the original Astron quartz watch, these timepieces offer precision and style. Key attributes include GPS control for accurate timekeeping across 39 time zones, including daylight saving adjustments. The perpetual day and date calendar, accurate until 2100, eliminates the need for frequent adjustments. A dual time function facilitates swift switching between main and secondary time zones. The blue dial features 3D indices and LumiBrite hands for visibility, enclosed by a durable blue sapphire crystal bezel. Constructed from lightweight titanium with a robust coating, the watches ensure comfort and resilience. With a screw-down case back, they guarantee water resistance up to 100 meters. The tri-fold push-button clasp ensures secure wear.

“Astron” is powered by a new GPS solar movement. Created for enhanced reception of solar signals allows for greater freedom in design. The watch will connect automatically up to twice a day* to the GPS network to maintain its precision of one second every 100,000 years. Experience a higher level of timekeeping precision with Astron.

*When the dial detects sunlight, the watch will connect to the GPS satellite network and adjusts automatically to the correct time. When light is not detected the watch remembers the last successful manual connection and attempts to receive the GPS signal again at that same time.
