Seiko unveils a 145th anniversary collection within the Astron line, introducing the GPS Solar Dual-Time Chronograph models HAB001, HAB002, HAB003, and HAB004. The series is powered by the new Calibre 5X63, which combines GPS-controlled time and time zone adjustment with a dual-time display and chronograph functionality measuring up to 24 hours in 1/20-second increments. The movement also includes a perpetual calendar correct to the year 2100, automatic daylight saving time adjustment, and a power save function.
The watches feature titanium cases with super-hard coating and a case size of approximately 43.4mm in diameter and 12.4mm in thickness. The dial layout places sub-dials in a horizontal, symmetrical arrangement, with variations across the four models including different dial colors and accent treatments. One version is a limited edition of 2,000 pieces, while others are standard production models within the Astron collection. The design includes sapphire crystal with super-clear coating and a quick-change strap system allowing easy bracelet or strap replacement.
