Description
The Seiko Astron SSH180J1 is a high-tech timepiece built for global living. Powered by GPS solar movement, it automatically adjusts to your time zone and runs for up to six months on a full charge.
It features a chronograph, dual-time display, perpetual calendar (good until 2100), and world time across 38 cities—all packed into a sleek 44.3mm case with a super-clear sapphire crystal.
LumiBrite ensures visibility in the dark, while the smart-adjusting clasp and 10-bar water resistance make it practical for everyday wear. As a limited edition, it’s engraved with a unique serial number, blending innovation with exclusivity.
