Prospex Alpinist GMT. 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 recreations and reinterpretations of landmark achievements.

Inspired by Seiko’s first sports watch, the 1959 Alpinist, this rugged, yet stylish, watch features the iconic wedge-shaped markers, bold numerals & stylized hands of the original, along with 24-hour GMT timing. An upgraded curved sapphire crystal with anti-reflective inner coating adds reliable visibility, while the new inner rotating compass bezel makes it ideal for hiking and outdoor activities. Framed by a 24-hour GMT bezel, the classic black dial includes a date calendar, LumiBrite hands & markers, and a red-tipped GMT hand.
