The Seiko Prospex Speedtimer SSC931 wears its racing inspiration in vivid color. A bright blue dial, three black subdials and a red chronograph seconds hand recall vintage race-car graphics, while the design pays tribute to Seiko’s landmark 1969 Speedtimer.

Why this watch stands out

Its solar chronograph measures up to 60 minutes in fifth-second increments and supports split-time measurement. A 24-hour display, power-reserve indicator and date window add everyday utility, and the movement offers up to six months of reserve when fully charged. LumiBrite hands and markers sit beneath curved sapphire crystal with an anti-reflective inner coating. The steel bracelet closes with a folding clasp, and water resistance is rated to 100 meters.

Our take

The SSC931 stands apart through its confident color scheme. It captures the energy of vintage motorsport without asking you to give up the convenience of solar-powered timing.

Seiko's journey, which began in 1881, is a remarkable story of vision, innovation, and dedication. When Kintaro Hattori, a 21-year-old entrepreneur, opened his small shop in Tokyo’s bustling Ginza district, he laid the foundation for what would become one of the world’s most respected watchmaking companies. Initially, Hattori focused on selling and repairing watches and clocks, but his ambition was far greater. He envisioned creating timepieces that would not only be precise but also reflect the spirit of Japanese craftsmanship.
In 1892, just over a decade after opening his shop, Hattori took a significant step forward by founding Seikosha, a factory dedicated to producing wall clocks. The name "Seikosha" means "House of Exquisite Workmanship," and it represented Hattori’s commitment to quality. By 1913, Seikosha had produced Japan’s very first wristwatch, the Laurel, marking a historic milestone for both the company and the nation’s watchmaking industry.
