Seiko's Astron 5X Titanium Collection pays homage to the revolutionary 1969 Astron watch while introducing modern advancements. Crafted in lightweight and durable titanium, these watches echo the original's sleek design. The collection's standout feature is its GPS control, allowing effortless time and time zone adjustments across 39 zones. Daylight saving time changes are also automatically accommodated. The watches feature a perpetual day and date calendar, accurate until 2100, eliminating leap year adjustments. Dual time functionality lets users track two time zones, complemented by AM/PM indicators.

Ensuring accuracy, the watches display a signal reception indicator and offer a power save mode when not exposed to light. Powered by light energy through solar cells, battery changes are unnecessary. The silver dial hosts a date calendar, LumiBrite hands, and markers, visible under the dual-curved sapphire crystal with a super-clear coating. The watch is water resistant to 200m suitable for aquatic activities. Constructed with a secure screw down case back and tri-fold push button release clasp, the collection merges durability with convenience. Seiko's Astron 5X Titanium Collection seamlessly blends timeless aesthetics with modern technology, offering impeccable accuracy and convenience in a sophisticated package.

“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.
