Seiko Astron SSH023 GPS Solar Dual-Time Chronograph Men's Watch Black • GPS Solar Movement Calibre 5X63 • Sapphire Crystal

The Seiko Astron GPS Solar Dual-Time Chronograph in black combines cutting-edge GPS solar technology with the precision of a chronograph in a striking titanium case. The GPS-controlled movement Calibre 5X63 synchronises automatically with GPS satellites, setting local time to the second across 38 time zones — ideal for frequent travellers and precision enthusiasts. The black titanium case with super-hard coating gives the watch a sporty yet elegant appearance that is both robust and refined.

The chronograph measures elapsed time in 1/20-second increments, complemented by a dual-time function with 24-hour display and a perpetual calendar accurate until the year 2100. Automatic DST adjustment and a high-speed time zone function make the Seiko Astron the perfect companion around the globe. The double-curved sapphire crystal with Super Clear coating ensures maximum scratch resistance and excellent legibility. The solar cell reliably converts light into energy, with a power reserve of up to six months in energy-saving mode.
