Official description

Fifty years ago, Seiko transformed watchmaking with the first commercially available quartz watch, the Astron. Today's Astron Titanium Collection represents another step forward, reflecting the strong, sleek lines of the 1969 original, in light and durable titanium, while providing the highest degree of accuracy possible in a wristwatch — effortlessly. Available only in a single run of 2,500, with serial numbers engraved on each caseback, this extraordinary Limited Edition pays tribute to Seiko founder, Kintaro Hattori, on the 160th anniversary of his birth, with a gold caseback engraved with the circle and square "S" 1900 company trademark, the name Kintaro Hattori and his motto, "One Step Ahead of the Rest." Also commemorating this important birthday are the 16 facets of the black zirconia ceramic bezel, one for each decade. GPS controlled for high-speed time and time zone adjustment to 39 time zones, this remarkable timepiece includes a daylight saving time function, perpetual day and date calendar correct to the year 2100, dual time with time transfer function, and am/pm indicators. To ensure smooth operation, the watch is equipped with a signal reception result indicator and power save function. The solar cell is powered by light energy, with no battery change required. The rich black dial also features a date calendar and LumiBrite hands and markers, and is topped by a dual-curved sapphire crystal with super-clear coating. Crafted of stainless steel with a black super-hard coating for added durability, secure screwdown case
