Save The Sea Editions
The Prospex mission: to help protect the world’s oceans now and for future generations, and to secure this legacy for divers everywhere. Seiko Prospex supports various marine conservation activities through its "Save the Ocean" initiative.

Seiko's reputation for reliable and durable diver's watches was forged in the 1960's and 1970's when they were chosen by adventurers and researchers on expeditions to the north and south poles. Today, Seiko introduces into the Prospex collection modern re-interpretations of three legendary diver's watches from this period that draw their design inspiration from the glaciers that these pioneers saw and that shape the landscapes and seascapes of the Arctic and Antarctic. Each one has a dial that evokes a different shade of glacial ice, from deep blue to white.
