The Seiko Prospex Speedtimer Mechanical Measures What Matters

The Speedtimer has been a part of Seiko for decades, dating back to 1969 and the release of the company’s first automatic chronograph — indeed, the first automatic chronograph to hit the market. Looking back, it might be hard to understand today just how significant that release was, but it’s easy to see the impact those early watches have had in the decades since. The early Speedtimers were racing chronographs of the highest order. Robust, reliable, and built to thrive in an era of motorsport iconic for its high speeds, innovative cars, and dangerous racing, the Seiko Speedtimer was a watch a racer could count on regardless of the conditions on race day.
