Astron was created from Seiko’s passion for innovation. Lightweight with a hard coated titanium case and bracelet, under dual curve sapphire glass crystal is a slate blue dial with a vertical subdial layout and horizontal line pattern. This piece was designed to have a low centre of gravity. The five-piece bracelet is crafted from titanium & has a micro-adjustable clasp. It features a new in-house 5X83 solar-powered movement & also features a 1/20th of a second chronograph function for measuring elapsed time. The subdial at 12 o’clock is for the chronograph feature, at 9 o’clock for setting modes, & at 6 o’clock for a dual-time feature. Seiko Astron: the world’s first GPS solar watch – powered by light, automatically adjusted to your exact time through the latest satellite technology.
