Seiko Prospex Antarctica Tuna ‘Save the Ocean’
This timepiece is inspired by the landscape of the world’s largest marine sanctuary – Antarctica. The dial’s graduated colour and texture echo the white-blue views of the area created by light reflected on the ice, whilst the penguin footprints represent the dwindling numbers of its inhabitants.
Seiko donates proceeds from these ‘Save the Ocean’ models to sea conservation and environmental organizations.
Prospex is a combination of the words ‘Professional’ and ‘Specifications.’
Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike.
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.
Comes with special edition ‘Save the Ocean’ box.
