Seiko Prospex 1970 Heritage Diver’s Watch Save the Ocean Special Edition ‘Glacier SPB301J1 SPB301

Prospex Glacier Special Edition ‘Save the Ocean’ 1970 Re-Interpretation

This specific design is inspired by Seiko’s 1970 Diver’s 150m watch – worn by Japanese explorer Naomi Uemura from 1974 to 1976 during his solo dog sled from Greenland to Alaska, a journey of 12,500km.

This ‘Save the Ocean’ Glacier Special Edition, inspired by the ice of the North Pole, expresses the accumulation of time and the time it takes for a glacier to form its beautiful structure. The dial pattern and colour express the natural formations and pressure the glacier underwent during its long cooling period. Glaciers formed during the ice age, approximately 150 to 3 million years ago. The case shape is the same distinctive shape as the 1970 classic, which proved its strength and endurance when worn by Naomi Uemura.

Prospex is a combination of the words ‘Professional’ and ‘Specifications.’ These timepieces are designed to be practical, reliable and durable within extreme or everyday environments, for experts, sports lovers and adventure seekers alike. Since launching Japan’s first diver’s watch in 1965, Seiko’s innovative watchmaking has changed global dive watch standards.

Seiko donates proceeds from Save The Ocean models to sea conservation organisations.
