The Seiko Astron SSH183J1 is a high-tech timepiece built for global travelers and modern professionals. Powered by GPS solar movement (Caliber 5X83), it automatically adjusts to your time zone and offers up to six months of power on a full charge, with a two-year reserve in power-save mode.
It features a 12-hour chronograph, dual-time display, perpetual calendar (good until 2100), and world time across 38 cities—all packed into a lightweight titanium case with ceramic/aluminum bezel. At 43.4mm wide and water-resistant to 10 bar, it’s durable, stylish, and smart.
