This Seiko Astron GPS Solar watch commemorates 100 years of Seiko with an elegant design inspired by Earth’s nighttime view from space. Featuring a black dial with a radiant pattern and rose-gold accents, it sits under a dual-curved sapphire crystal. The slim titanium case, paired with rose-gold-plated ceramic on the bezel and bracelet, creates a lightweight yet durable construction with a super-hard coating for scratch resistance. Powered by the advanced in-house 5X83 solar GPS calibre, this watch offers precise timekeeping with a chronograph that measures to 1/20th of a second. With a 6-month power reserve and light charging capabilities, it combines innovation with timeless elegance.
