On December 25, 1969, SEIKO introduced the world's first quartz watch to the market: "SEIKO ASTRON". This revolutionary watch at the time boasted a remarkable difference of precision of - / + 1 second per day and had an autonomy of more than 12 months: a real revolution in the world of watchmaking. In 2012, the Maison reached a new milestone, a milestone in watchmaking history, with the world's first SEIKO ASTRON GPS SOLAR watch. With atomic precision, this timepiece works solely on solar energy and adjusts the time zone with the push of a button. It was an honor to call it "ASTRON", in honor of the first SEIKO ASTRON, synonymous with a great new technological innovation.
