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, breaking through to a new future with excellence in both innovation and style. Offering high-speed GPS time zone adjustment to 39 time zones, exceptional new Astron designs are equipped with Seiko’s 5X83 caliber which provides both a dual-time function and a chronograph that measures elapsed time in 1/20th second increments. The chronograph series showcases four subdials on the dial, laid out vertically for a sporty look, a first for Seiko Astron, and includes a time transfer function that allows to user to switch the main time and dual time indications with the push of a button. Crafted of light and durable titanium with super-hard coating, with 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, the newest Astron models feature a tri-fold push button release clasp with smart-adjust function that provides micro-adjustments to the length of the bracelet, achieving a superior fit.
