About the Astron Silver & Gold GPS Solar Watch with Gold-tone Accents SAST005

True to its tradition of World's Firsts in watchmaking, Seiko brings you the world's first GPS solar watch. With a single touch of a button, the Astron GPS Solar watch automatically adjusts to the correct local time, no matter where you are on the planet.

Astron receives all the power it needs from light absorbed through the dial. It uses all kinds of light and has a power reserve indicator to show the amount of energy stored. You'll never need to worry about the battery dying or needing replacement. Even better, you can feel confident that you'll always be on time with Astron's precision accuracy. Astron receives a time signal from the Atomic Clocks in each GPS satellite, making it accurate to one second every 100,000 years, even when walking or moving in a vehicle.

Beyond the impressive functions and features of the new Astron, Seiko has pulled out all the stops to make Astron sleek, stylish, and a pleasure to wear. The titanium case and bracelet are stronger than stainless steel yet remarkably lightweight. In addition, both the front and back of the sapphire crystal have been coated with Seiko's proprietary, newly developed anti-reflective Super-Clear Coating. This coating prevents 99% of light reflection and allows the dial to be easily legible, even in bright light.

The SAST005 has a black ceramic bezel that contrasts the silver case and bracelet, creating a classic two-tone look. The black dial is accented with white and gold-tone hour markers and gold-tone hands. A date window is located at the 3 o'clock position.

The Astron GPS Solar SAST005 is a must-have for both collectors and those who simply appreciate advanced technology, exceptional quality, and beautiful design.
