Seiko Astron

Slate Blue Dual-Time Chronograph GPS Solar Watch

The Seiko Astron SSH175J1 is driven by Seiko’s passion for innovation and created under the design theme of Solidity, representing the future of advanced watchmaking. This solar-powered Astron model combines cutting-edge technology with a strong yet refined aesthetic, designed for modern lifestyles.

Lightweight yet robust, the watch is crafted from super-hard coated titanium, including both the case and bracelet, and is protected by dual curved sapphire crystal glass. The blue-grey dial features a distinctive vertical subdial layout with a horizontal line pattern, enhancing its contemporary character. With sleek lines, a slim profile and a compact, angular design, the case flows almost seamlessly through the lugs to the bracelet, creating a balanced and modern look.

Designed with a low centre of gravity for enhanced comfort, the five-piece titanium bracelet offers lightweight wear and includes a micro-adjustable clasp for a personalised fit. The caseback is finished with a three-dimensional globe symbol, highlighting its GPS capability. Powered by the in-house 5X83 solar movement, the SSH175J1 features a 1/20th of a second chronograph, with subdials dedicated to chronograph timing, mode selection and dual-time display. As part of the Seiko Astron collection — the world’s first GPS solar watch — it is powered by light and automatically adjusts to the exact time via advanced satellite technology.
