Seiko Astron GPS Solar 2026 Limited Edition
A design featuring a mysterious galaxy of swirling stars.
This watch’s dial features a newly developed embossed spiral pattern, which radiates from the centre to convey the energy of flowing stars. The all-black case and bracelet, paired with a dark turquoise-coloured dial infused with glitter, evokes the image of swirling galaxies emerging from the pitch-black cosmos.
The case and bracelet are finished with a scratch-resistant hard coating designed to maintain a jet-black sheen. The clasp’s adjustment system allows for easy fine-tuning of the bracelet’s length.
