Cazalea introduces the 2023 Seiko Prospex collection, highlighting significant updates to their diver's watch lineage. This post offers a comprehensive look at new models, including a limited edition honoring adventurer Naomi Uemura and re-imagined 1968 GMT Divers, providing crucial details for collectors tracking Seiko's latest offerings.
Five years after making Japan’s first diver’s watch in 1965, Seiko introduced a new diver’s watch with a flowing case design and an asymmetrical extension that protected the crown at the four o’clock position.
This 1970 diver’s watch proved its reliability in extreme conditions when it was worn by Japanese adventurer Naomi Uemura in the Arctic region.
Born in 1941, Naomi Uemura was a university student when he took on the challenge of his first mountain climb. By the age of 29, he had climbed Mont Blanc, Mt. Kilimanjaro, and Mt. Aconcagua, and, in 1970, he became the first Japanese mountaineer to reach the summit of Mt. Everest. Just three months later, he reached the top of Alaska’s Denali (then known as Mt. McKinley) and thus became the first adventurer in the world to reach the summits of all five of these peaks. Today, Uemura’s ascents of these five mountains are commemorated with a 500-piece limited edition watch whose dial depicts Mont Blanc, the first of these climbs.
