Seiko Astron – GPS Solar Limited Edition of 1,500 pieces Chronograph Turquoise Dial 5X83 43.3mm SSH187

Description

With the strong, sleek lines 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 the future with excellence in both innovation and style. Available only in a controlled-production run of 1,500, with the serial number engraved on each caseback, this dynamic timepiece evokes a swirling galaxy in the vast darkness of space. Framed by a titanium bezel with turquoise accents and a glossy ceramic insert, the dark turquoise patterned dial has a subtle sparkle expressing new stars being born to the spiral galaxy and their unknown trajectories. 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 high precision timepiece 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. The unique turquoise dial displays four subdials, a date calendar, and LumiBrite hands and markers. Crafted of light and durable titanium with black super hard coating, this superb creation also includes a sapphire crystal with super-clear coating, secure screwdown caseback, and tri-fold push button release clasp with Smart Adjuster function.
