Prospex Alpinist. 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 a long history of sports watch excellence with re-creations and re-interpretations 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 green dial with date calendar and LumiBrite hands and markers, as well as a curved anti-reflective sapphire crystal. The 24-jewel automatic movement beats at a frequency of 21,600 vibrations per hour, with a power reserve of approximately 70 hours, and can be wound manually or automatically. Crafted of stainless steel, with screwdown crown, see-through caseback, and secure tri-fold push button release clasp. 20 bar, 200M Water Resistant
