The Seiko Astron SBXC179 is powered by the Caliber 5X83 solar GPS satellite radio-controlled movement, which runs on light and adjusts time zones at the push of a button. The titanium case and band are coated with Super Black Diamond Shield, and it offers 10-bar water resistance, sapphire crystal, world time for 38 time zones, a perpetual calendar, and more. Made in Japan and released in May 2025 as a Seiko Core Shop exclusive.
