Celebrating 110 Years of Watchmaking Excellence

The long-running Seiko Prospex Alpinist has quietly remained a distinctive, highly functional tool watch, marrying dependable timekeeping with the time-honored traditions of an inner rotating compass bezel for the wilderness-savvy. The next generation of this classical mountaineering instrument is now equipped with a third degree of utility: a 24-hour complication, yielding the new Seiko Prospex Alpinist GMT. 

To mark 110 years of watchmaking excellence, Seiko is highlighting its continuous dedication to evolving technology, as well as diversity, equality and the sustainable manufacturing necessary to meet environmental challenges. This distinctive Limited Edition, available only in a controlled-production run of 3,000, was inspired by Seiko’s first sports watch, the 1959 Alpinist, and features the iconic wedge-shaped markers, bold numerals and 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 inner rotating compass bezel makes it ideal for hiking and outdoor activities. Framed by a 24-hour GMT bezel, the white sunray dial with distinctive blue and red accents includes a date calendar, LumiBrite hands and markers, and a GMT hand.

The 24-jewel automatic movement, visible through the see-through screwdown caseback, beats at a frequency of 21,600 vibrations per hour and offers an exceptional power reserve of 72 hours, as well as manual winding capability. Crafted of stainless steel with durable super-hard coating and a secure screwdown crown, this superb timepiece also comes with an additional dark brown sustainable leather strap, certified by the Leather Working Group (LWG), and both bracelet and strap include a tri-fold push button release clasp. Packaged in a white 110th Anniversary Limited Edition collector’s box.
