About this timepiece

Cool, confident and built for timing, the Seiko Prospex Speedtimer Solar Chronograph (ref. SSC939) sets a gray dial with black subdials inside a blue tachymeter bezel, while a cream outer track adds a warm vintage note. At 41.4mm across, the stainless steel case gives this chronograph a generous, assured presence on the wrist. LumiBrite on the hands and indexes keeps the time easy to read once the light fades.

Seiko's solar caliber V192 runs on light and keeps going for approximately six months once fully charged, with an overcharge prevention function and a power reserve indicator to keep track of the charge. Its chronograph counts in 1/5-second steps for up to 60 minutes, working alongside the tachymeter function on the bezel, while a 24-hour hand, small seconds and a date display round out the dial. A curved sapphire crystal with an anti-reflective coating on its inner surface sits over the dial, and with a screw case back, 10 bar water resistance and a stainless steel bracelet on a three-fold push-button clasp, it is a sports watch made for everyday wear.

Features

  • V192 solar movement – runs approximately 6 months on a full charge, with overcharge prevention.
  • 60-minute chronograph – times events in 1/5-second steps and pairs with the tachymeter function.

  • 41.4mm stainless steel case – with a screw case back and 21mm between the lugs.

Timepiece History

Seiko's story began in 1881, when a 21-year-old entrepreneur, Kintaro Hattori, opened a shop selling and repairing watches and clocks in central Tokyo. The first watch to carry the Seiko name followed in 1924, and Seiko went on to introduce a long line of watchmaking firsts, including the Quartz Astron, the world's first quartz wristwatch, on December 25, 1969. In 2024, Seiko celebrated the 100th anniversary of the Seiko brand.

The SSC939 is part of the Prospex Speedtimer series, inspired by Seiko's long tradition in sports timing. In the 1960s, Seiko built high-precision stopwatches around its innovative heart-shaped cam mechanism, including a 1/100-second stopwatch that served as an official timing device at the world sporting event held in Tokyo in 1964, and in 1969 Seiko introduced the Speedtimer with Caliber 6139, the first automatic chronograph with a column wheel and vertical clutch.
