SEIKO PROSPEX Mod. SPEEDTIMER SSC947P1

In 1969, Seiko made horological history by releasing the world's first automatic chronograph equipped with both vertical clutch and column wheel—the legendary Seiko Speedtimer. This groundbreaking achievement established Seiko as a pioneer in chronograph technology and set new standards for precision timing instruments.

Protected beneath a curved sapphire crystal lies a vibrant yellow dial that pays homage to the characteristic design of the original 6139 model. The striking bright red second hand and subdial minute hand at 6 o'clock create a bold visual contrast that enhances both aesthetics and functionality. Featuring 12 strategically placed LumiBrite spots across each of the wide vintage-style indices, this Speedtimer ensures exceptional legibility even in the darkest conditions. True to the original's design philosophy, this piece showcases a distinctive blue and red aluminum bezel with integrated tachymeter function and a chronometer second scale on the inner dial ring. The elegantly tapered bracelet flows seamlessly from the lugs to the buckle, creating a refined silhouette. This modern interpretation harnesses the power of the advanced V192 solar chronograph caliber, which efficiently charges using both natural and artificial light sources. With remarkable accuracy of ±15 seconds per month and an impressive 6-month power reserve when fully charged, this timepiece represents the perfect fusion of heritage design and cutting-edge solar technology.
