Seiko 145th Anniversary Limited Edition. Seiko Prospex challenges every limit with timepieces created to exceed expectations, engineered with superior style and innovative technology for the sea, sky or land. Commemorating 145 years of Seiko timekeeping excellence, and available only as part of a Limited Edition series, this exceptional creation showcases a captivating purple dial evoking Edo-Murasaki, a traditional hue representing hope for the future. Inspired by Seiko’s first sports watch, introduced in 1959 for daring mountaineers, the tailored, yet rugged timepiece celebrates the rise to high-intensity timekeeping by prominently displaying the Alpinist logo on the dial. Framed by a rotating inner compass bezel for outdoor adventure, the striking dial displays the signature Arabic numerals and wedge-shaped indices of the series, as well as LumiBrite hands and markers for the ultimate clarity in low light situations. 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, it is paired with a black leather strap sourced from an LWG certified tannery. 20 Bar, 200m Water Resistant.
