This Prospex watch is from Seiko's "Save The Ocean" collection. The dial of this special edition timepiece represents the view of the ocean as seen by the 5m deep vision of the Manta Ray endangered species. Its colours echo the gradations of sunlight refraction and the patterns symbolise waves seen from under the sea. Seiko donates proceeds from Save The Ocean models to sea conservation organisations.This watch shape is nicknamed by Seiko fans as a ËSamurai - because of its angular shaped design which looks as if it were sliced by a Japanese Samurai sword
