Seiko - Prospex Sea, Stainless Steel - Save the Ocean Special Edition Automatic with manual winding, Size 40.5mm SPB297J1

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.

The 1965 diver's watch incorporated an automatic mechanical caliber and delivered 150m water resistance. The watch was designed for maximum reliability and legibility in the harshest conditions. It proved its reliability when used in the Antarctic during the 60s and laid the path to the development of future landmark watches.
