Astron GPS Solar Dual-Time Chronograph. Extending the legacy of the Seiko Astron, the world’s first commercially available quartz watch, today’s Astron is designed for a new generation of leaders to break through to a new future with excellence in both innovation and style. Combining solid tailoring with the highest degree of accuracy possible in a wristwatch, this exceptional timepiece is equipped with Seiko’s 5X83 caliber, offering both high-speed GPS dual time and time zone adjustment to 39 time zones and a chronograph function that measures elapsed time in 1/20th second increments. The movement also features an AM/PM indicator, daylight saving time function, power save function, perpetual day/date calendar correct to the year 2100, and a time transfer function that allows the user to switch the main time and dual time indications with the push of a button, all powered by light energy with no battery change required. Framed by a titanium bezel with a black ceramic tachymeter insert, and topped with dual curved sapphire crystal with super-clear coating, the silver dial displays a distinct texture, made possible by improved charging efficiency of the solar cell, providing an outstanding contrast to the subdials. In addition to the four subdials, laid out vertically for a sporty look, a first for Seiko Astron, the dial includes a date calendar and LumiBrite hands and markers. Crafted of light and durable titanium with super-hard coating, this superb timepiece has a contemporary feel thanks to the sleek lines, slim profile, and the compact and angular design that seamlessly flows from the case to the bracelet and includes a secure screwdown caseback and tri-fold push button release clasp with Smart Adjuster function. 10 bar, 100M Water Resistant. Verified details include bracelet material of Stainless Steel, brand collections of Astron, dial colour of Silver, diameter of 43mm, guarantee of Seiko 3 Year Guarantee and movement of Automatic.
