Story A solar-powered timepiece with a ’70s motorsports aesthetic Inspired by Seiko’s original 1969 Speedtimer watch—the world’s first self-winding chronograph—the Prospex Speedtimer features a curved, sapphire crystal that’s been treated with an anti-reflection coating. And it’s solar-powered by Seiko’s Caliber V192 movement, which has an impressive 6-month power reserve once fully charged. The SSC813 features a sand-blasted white dial, contrasting black subdials, and a black tachymeter bezel. What’s more, there’s a 24-hour sub-dial as well as 2 additional sub-dials for the Prospex’s chronograph feature, which records up to 60 minutes of elapsed time in 1/5-second increments. Last but not least, LumiBrite hands and markers provide a crystal clear view of both time and the date window.

Founded in 1881 by entrepreneur Kintaro Hattor in the heart of Tokyo, Seiko knows every nook and cranny of what makes an elite watch truly incredible. In those 130+ years, they came up with lasting innovations like the first quartz watch, the first titanium dive watch, and the first multi-functional digital watch. Needless to say, Seiko continues to push the watch game forward.
