This Seiko Speedtimer Solar Chronograph pairs purposeful design with easy, everyday function. The solar powered movement stays charged by light and delivers about six months of reserve without battery changes. A black and gray tachymeter bezel frames a clean dark dial with green LumiBrite hands for quick reading in any light. The chronograph measures up to 60 minutes with split time, and a curved sapphire crystal plus 100 meter water resistance handle daily wear. Inspired by the 1969 Speedtimer, it offers heritage style with modern performance.
