Description
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, the 1959 Alpinist, this rugged, yet stylish, watch is equipped with a rotating inner compass bezel for outdoor adventure and a prominent red 24-hour GMT hand to track the time in a second time zone. The iconic design features a green dial, a color theme pulled from the archives, with the signature gold-tone Arabic numerals and wedge-shaped indices of the series as well as LumiBrite hands and markers for outstanding clarity in low light conditions. 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, this exceptional creation is paired with a brown leather strap sourced from an LWG certified tannery.
