Seiko Astron GPS Solar Limited Edition SSJ029J1

Inspired by the enchanting beauty of cherry blossoms under a starry sky, this Seiko Astron timepiece features a glittering purple gradient dial with a star trail-inspired pattern, housed in a sleek black titanium case and bracelet with a super-hard scratch-resistant coating. The design reflects Japan’s ‘yozakura’—cherry blossoms illuminated at night—capturing their ethereal glow. Lightweight titanium construction, a micro-adjustable clasp, and a slim profile ensure modern comfort. Powered by the in-house 3X62 Solar GPS movement, it offers precise timekeeping, automatic time zone adjustment via GPS satellites, and charging by any light source. A perfect blend of elegance and innovation.
