This limited edition is one of a trilogy of timepieces inspired by the dense verdant forest on Japan’s Iriomote Island– one of the world’s best places for diving. Subtropical primeval forests cover most of the island, enriching the surrounding waters, nourishing the coral reefs, said to be among the world’s biggest and most diverse.

Solar-powered, the watch charges from both natural and electric light.The shape of this watch is affectionately named ‘Sumo’ by Seiko fans – because of its size and shape and the 12 o’clock marker – it’s a substantially strong looking timepiece.

Seiko Prospex watches are designed for sports lovers and adventure seekers whether in the water, in the sky or on land. Since launching Japan’s first diver’s watch in 1965, Seiko’s innovative watchmaking has changed global dive watch standards. Sold with commemorative box.
