Prospex Alpinist. Seiko Prospex challenges every limit with timepieces created to exceed expectations, engineered with superior style and innovative technology for the sea, sky or land. Driven by a heritage of iconic design, Prospex continues to keep going forward with excellence in precision timekeeping, crafted for the modern world. Inspired by Seiko’s first sports watch, introduced in 1959 for daring mountaineers, this tailored, yet rugged creation celebrates the rise to high-intensity timekeeping by prominently displaying the Alpinist logo on the dial. Equipped with a rotating inner compass bezel for outdoor adventure, the iconic design features a teal dial, a color theme pulled from the archives, with the signature Arabic numerals and wedge shaped indices of the series as well as LumiBrite hands and markers. Visible through the transparent caseback, marked with the trademark Alpinist “mountain” symbol, the 24-jewel automatic movement beats at a frequency of 21,600 vibrations per hour with a power reserve of approximately 72 hours and manual winding capability. Crafted of stainless steel with super-hard coating, with tri-fold push button release clasp and secure screwdown crown. 20 Bar, 200M Water Resistant
