Over forty years ago, Seiko introduced the world's first solar-powered chronograph with a 1/100th-second stopwatch.Over forty years ago, Seiko introduced the world's first solar-powered chronograph with a 1/100th-second stopwatch. The SFJ005 marked that anniversary as a limited-edition addition to the Prospex Speedtimer line, with four subdials covering 1/10-second, 1/100-second, and full-second stopwatch functions alongside a 60-minute elapsed time display activated by the Mode pusher at 8 o'clock. The charcoal grey face sits under sapphire crystal, with black subdials and a center-linked bracelet in grey. Inside, Seiko's 8A50 solar-powered quartz movement carries a six-month power reserve, and the screw-down caseback is engraved with the production serial number. A chronograph that took over 40 years to deserve a sequel.
