Description
The Seiko Astron GPS-Dual Time Chronograph SSH179J combines cutting-edge GPS technology with sleek titanium construction for unmatched precision and comfort. Its Calibre 5X83 movement powers the watch using solar energy from any light source, eliminating the need for a battery. This dual-time chronograph automatically adjusts to your exact location via GPS satellites, maintaining accuracy to within ±1 second every 100,000 years.
This solar watch offers a power reserve of up to two years on a full charge, ensuring reliable performance even during extended periods without light exposure. The 44.1mm black titanium case and matching bracelet provide strength and lightweight comfort, while water resistance up to 100 metres allows safe use for everyday wear and light water activities.
The analogue black dial features Lumibrite hands and markers for excellent visibility in low light, protected by dual-curved sapphire crystal with Super Clear Coating. The perpetual calendar automatically accounts for short months and leap years, keeping the date accurate until February 2100. Additional indicators include the day of the week, AM/PM, hour, minute, and seconds.
Travelers will appreciate the dual-time function, which allows you to view a second time zone on either the sub-dial or main hands. The watch also supports automatic daylight saving adjustments, manual time setting, and a precise chronograph that measures up to 12 hours in 1/20th-second increments. A power reserve indicator lets you monitor its energy status at a glance.
Limited to sophisticated enthusiasts, Seiko Astron GPS-Dual Time Chronograph SSH179J is a solar-powered, GPS-enabled titanium watch that merges advanced technology with elegant design—ideal for international travelers, sports timing, and everyday reliability.
