Seiko Prospex Antarctica Scuba Tuna ‘Save the Ocean’ This timepiece is inspired by the landscape of the world’s largest marine sanctuary – Antarctica. The dial’s graduated color and texture echo the white-blue views of the area created by light reflected on the ice, whilst the penguin footprints at the 10 o’clock position represent the dwindling numbers of its inhabitants. Seiko donates proceeds from these ‘Save the Ocean’ models to sea conservation and environmental organizations. The shape of this watch is affectionately nicknamed by Seiko fans as a ‘Tuna’ – because of its larger diameter and bold shape like a tuna tin – loved for decades since its release. Seiko Prospex watches are designed for sports lovers and adventure seekers in the water, in the sky or on land – and are robust for everyday wear, whatever the environment. Since launching Japan’s first diver’s watch in 1965, Seiko’s innovative watchmaking has changed global dive watch standards.   Be sure to check out the Seiko Marine Master too.
