Naomi Uemuraadventurer
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 Mt. Kilimanjaro, Mont Blanc and the Matterhorn. In 1970, he became the first Japanese mountaineer to reach the summit of Mt Everest. Just three months later, he reached the top of Denali in Alaska (then known as Mt. McKinley) and thus became the first adventurer in the world to reach the tallest peaks on all five continents. In the winter of 1984, he succeeded in climbing Denali in winter but disappeared forever on the descent. Famed for his modesty as much as his achievements, Uemura was given the National Honor award shortly after his disappearance.
Dial
This commemorative watch echoes the design of the 1970 original but is thoroughly modern in execution. The patterned dial evokes the mountainous terrain that Uemura so loved, and the dial and bezel are in the blue tones of the earth's upper atmospheric layers that only those who, like him, have been to the roof of the world can see. Uemura was the first person in the world to reach the summits of the highest mountains on all five continents.
Case design
The case sides are carefully polished and the watch is presented on a five row steel bracelet to create a modern sharp profile. The case has the distinctive asymmetrical shape to protect the crown at the 4 o'clock position.
Enhanced specifications
The case has a super-hard coating to protect the watch from scratches and the curved sapphire crystal with anti-reflective coating on the inner surface to ensure high legibility from every angle. The watch has enhanced water resistance to 200 meters.
Additional strap
The additional blue silicone strap has the train track pattern as the original is also offered.
Case back
The case back is marked with Uemura's name and carries the individual watch's serial number.
* In an actual product, the case back direction might be different from the photograph.
