Seiko revives an archival design with a few modern updates. Based on one of the world's first automatic chronographs, the Prospex SSC911 Speedtimer Solar Chronograph revives the 1969 design with a 41.4 mm stainless steel case and bracelet. A black and gray tachymeter bezel surrounds the silver dial with a sunray finish and black subdials. Red seconds hands offer a bold contrast, while LumiBrite hands and markers enhance readability at night. Powered by a Caliber V192, the watch features 100 meters of water resistance and a six-month power reserve.
