Seiko Prospex “Ice Diver” Sumo USA Special Edition – A Tribute to Polar Exploration

Introducing the Seiko Prospex Ice Diver Sumo Series—crafted for those who dare to explore the extremes. Inspired by the icy landscapes of the world’s polar regions and launched in honor of the legendary Japanese adventurer Naomi Uemura’s historic Mt. Everest ascent 50 years ago, this exclusive USA-only release celebrates Seiko’s legacy of precision under pressure.

Three Glacier-Inspired Dials – SPB175, SPB177, SPB179. This limited series features three stunning dial variations, each echoing the shifting tones of glacial ice:

• Grey Dial SPB175 – A nod to the raw, untouched face of frozen terrain

• Green Dial SPB177 – Reflecting the mossy hues beneath melting ice

• Blue Dial SPB179 – Capturing the deep, crystalline blues of ancient glaciers

Each dial showcases a unique waffle texture, engineered to reflect light through angular facets—offering a refined shimmer that elevates the Sumo’s rugged silhouette.

Built for Adventure, Styled for Collectors Housed in a robust 45mm stainless steel case with 200M water resistance, the Ice Diver Sumo retains its iconic profile while integrating modern upgrades. Powered by Seiko’s reliable Caliber 6R35 automatic movement, it delivers a 70-hour power reserve and smooth performance in any condition. A scratch-resistant sapphire crystal ensures clarity and durability, while the bold dial textures add a touch of luxury to this tool watch.
