Seiko SSC813 Prospex Speedtimer Solar Chronograph White Dial Watch

Seiko SSC813 Prospex Speedtimer

The Speedtimer name carries weight—Seiko’s history with timing sports events goes back decades. The SSC813 takes that heritage and packages it in a solar chronograph that looks the part without the mechanical price premium.

The Panda Dial

White dial, black subdials—the classic “panda” layout that racing chronographs made famous. The sand-blasted texture on the dial adds depth without being distracting. Three subdials handle small seconds, 60-minute timing, and 24-hour tracking. Date window at 4:30 stays out of the way.

Solar Power Done Right

The V192 caliber converts light to power with a 6-month reserve when fully charged. That means no battery changes and no winding—just wear it. Chronograph measures 60 minutes in 1/5-second increments with split-time capability. ±15 seconds per month accuracy beats any mechanical.

Speedtimer Specs

At 39mm with a 45.5mm lug-to-lug, it wears smaller than modern sport chronographs—closer to vintage proportions. The black tachymeter bezel adds motorsport utility. Sapphire crystal with anti-reflective coating is unusual at this price—most competitors use Hardlex.

The Proposition

The Speedtimer delivers chronograph looks and function with solar convenience. The panda dial, sapphire crystal, and Prospex build quality make it competitive with chronographs costing significantly more. For actual timing use, solar beats mechanical anyway.
