Seiko Astron – Titanium GPS Solar 2026 Limited Edition of 1,500 pieces Turquoise Dial 41.2mm SSJ039

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 strong and distinctive octagonal titanium bezel, the dark turquoise patterned dial has a subtle sparkle expressing new stars being born to the spiral galaxy and their unknown trajectories. Combining solid tailoring with the highest degree of accuracy possible in a wristwatch, it is powered by Seiko’s GPS solar caliber 3X62, GPS controlled for high-speed time and time zone adjustment to 39 time zones with an in-flight mode and perpetual date calendar correct to the year 2100. To ensure smooth operation, the watch is equipped with a signal reception result indicator, a power save function, and a highly efficient solar cell powered by light energy, with no battery change required. The unique dark turquoise dial offers a multi-function indicator subdial for easy mode reference, as well as sharp, highly visible three-dimensional applied indices and LumiBrite hands and markers. Crafted of light and durable titanium with black super hard coating, this superb timepiece also includes a sapphire crystal with super-clear coating, secure screwdown caseback, and tri-fold push button release clasp with Smart Adjuster function.
