Seiko Astron GPS Solar 2025 Limited Edition SSH183J1

The Seiko Astron GPS Solar 2025 Limited Edition SSH183J1 is a special model that combines bold design with a dynamic colour scheme. The horizontal pattern on the dial is inspired by the speed of light, while the two-part bezel fuses ceramic elements with a striking neon orange accent ring. Together, the black and neon orange details give this timepiece a sporty and daring look.

At its heart is the high-precision 5X83 GPS Solar movement, powered by light, with a power reserve of around six months on a full charge and up to two years in power-saving mode. Time adjustment is automatic via GPS signals anywhere in the world, with an accuracy of ±15 seconds per month without GPS reception.

The case is crafted from lightweight, durable titanium with a Super-Hard-Coating. The black dial is protected by a sapphire crystal with a Super-Clear coating, while LumiBrite on the hands and indexes ensures excellent legibility. The titanium bracelet with a ceramic centre link is secured with a three-fold clasp with push button and Smart Adjuster function.

A wealth of functions makes the SSH183J1 ideal for travellers and active wearers: world time for 38 cities, dual-time function, chronograph up to 12 hours with 1/20-second accuracy, perpetual calendar until 2100, date display, automatic and manual time adjustment, DST (daylight saving time), flight mode, and automatic hand alignment. It also features a power reserve indicator, overcharge prevention, and power-saving function.

Limited to just 1,200 pieces, each individually numbered, the Seiko Astron GPS Solar SSH183J1 measures 43.4 mm in diameter, 13.4 mm in thickness, and weighs 123 g. With 100 m (10 ATM) water resistance and 4,800 A/m magnetic resistance, it is a premium watch that blends cutting-edge technology, refined materials, and bold design.
