1959 Sports Watch Reinterpretation. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. Part of a rich legacy of innovation in high-intensity timekeeping, Prospex continues to celebrate over 60 years of sports watch excellence with recreations and reinterpretations of landmark achievements. A modern reimagining of Seiko's first sport watch, introduced in 1959, this distinctive timepiece follows a highly successful Spring 2019 limited edition and more recent additions to the line. With a smaller case to fit contemporary tastes while evoking a vintage feel, this versatile watch features a gradated black dial with date calendar and LumiBrite hands and markers, as well as a curved anti-reflective sapphire crystal.
