Prospex Speedtimer Solar Chronograph - SSC813

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.

About Seiko

When we think of Seiko, one word comes to mind: legacy. 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.
