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 features the Alpinist logo on the dial and a rotating inner compass bezel for outdoor adventure. The green dial draws from the archives, with gold Arabic numerals and wedge-shaped indices complemented by LumiBrite hands and markers. A transparent caseback reveals the 24-jewel automatic movement, which beats at 21,600 vibrations per hour and offers an approximately 72-hour power reserve with manual winding capability. The stainless steel case has a super-hard coating and is paired with a brown calf leather strap sourced from an LWG certified tannery.
