Limited to just 1,200 pieces worldwide, the Seiko Astron GPS Solar 2026 Limited Edition HAB005J1 takes inspiration from the radiance of green quartz crystal. Its Crystal Green dial features a newly developed pressed pattern that recalls the sparkling facets of quartz, complemented by LumiBrite hands and baton hour markers. The lightweight 43.4mm titanium case and bracelet are treated with Seiko's super-hard coating, while sapphire crystal with a super-clear coating provides excellent clarity. A quick-change system enables the titanium bracelet to be exchanged for the included black silicone strap, and the watch is supplied in a special nylon presentation box. The Seiko calibre 5X63 GPS Solar movement connects to the GPS network to adjust the time and time zone while drawing its energy from light. Its extensive functions include world time across 38 cities, dual-time display, a 24-hour chronograph accurate to 1/20th of a second, a perpetual calendar, day display, power reserve indicator, time transfer, satellite acquisition and reception result displays, automatic hand-position alignment, and an in-flight mode. When fully charged, the watch operates for approximately six months, extending to around two years in power-saving mode. The individual edition number and Limited Edition wording are engraved on the screw-down case back, and the watch offers 100-metre water resistance. • Powered by the solar powered 5X63 calibre movement with 14 jewels and a power reserve of up to 6 months • Presented on a silver stainless steel bracelet with fold over clasp • Scratch resistant sapphire crystal glass with a super-clear coating • 43.4mm case width & 50.0mm case length measuring from lug to lug • 100 metre water resistance
