Seiko Astron GPS Solar 2024 Limited Edition The radiance of the early morning sky reflected in a watch

The black titanium case and bracelet take inspiration from the dark of the night sky. The glittering gradation dial expresses the sky as it gradually begins to light up from the dark of night.
The gold accents recall the radiance of Venus and other planets and stars in the early morning sky.
The indexes, as well as the hour, minute and seconds hands, are filled with Lumibrite, enhancing legibility in low-light conditions.
