Description

The Seiko Astron GPS Dual Time Chronograph Solar 2026 Limited Edition SSH187J represents the cutting edge of modern watchmaking, combining advanced GPS technology with a bold, futuristic design. Crafted from lightweight black titanium, the 43.3 mm case offers exceptional strength and comfort, while the blue textured dial adds depth and sophistication. Protected by dual-curved sapphire glass with Super Clear coating, the dial remains highly legible in all lighting conditions, enhanced further by Lumibrite hands and markers. With 100 metres of water resistance, this Astron is built for global travel and everyday wear alike.

Powered by Seiko’s Solar Calibre 5X83, the watch draws energy from any light source and delivers extraordinary precision of ±1 second every 100,000 years through daily GPS time synchronization. The dual time display allows the main hands and sub-dial to be independently adjusted to different time zones, making it an ideal companion for frequent travellers. Additional features include a perpetual calendar accurate until February 2100, a 12-hour chronograph with 1/20th-second precision, world time with automatic daylight saving adjustment, and a power reserve indicator with up to two years of autonomy. Limited to just 1,500 pieces worldwide, the SSH187J is a rare fusion of innovation, performance, and exclusivity within the Seiko Astron collection.
