Seiko Prospex challenges every limit, with a collection of timepieces for sports lovers and adventure seekers whether in the water, in the sky, or on land. To honor the 140th Anniversary, Seiko will celebrate watches inspired by the landscapes and seascapes of Japan. The green dial collection is inspired by the island of Iriomote in Okinawa Prefecture, stunning deep green scenery of the ocean that surrounds the island. Based on the 1968 Divers 300 meter water resistant watch, this model gives a modern design interpretation, whilst retaining the sharp and powerful design of the orginal.
