Description
The Seiko Astron SSH177J1 is a sophisticated GPS solar watch designed for precision and convenience. Housed in a lightweight titanium case with a super-hard coating, it features a 44.1mm diameter and a dual-curved sapphire crystal with a super-clear finish.
Powered by the advanced 5X83 movement, it automatically adjusts to your time zone via GPS and offers a 6-month power reserve, or up to 2 years in power save mode. It includes a 12-hour chronograph, dual-time display, perpetual calendar (valid until 2100), and world time across 38 cities.
LumiBrite ensures visibility in low light, while the allergy-safe metal and Smart Adjuster clasp add comfort. With 10-bar water resistance, magnetic protection, and a screw-down case back, the SSH177J1 is built for global adventures with a refined edge.
