Seiko Special Edition Prospex Save The Ocean Turtle Tuna PADI Solar Mens Watch SNE518P1 47mm Part of Seiko’s Save the Ocean series, this Seiko Prospex Save The Ocean Solar Chronograph Blue Mens Watch SSC701P1 43.5mm is a stunning addition to the Prospex lineup. As is the case with the entire Save the Ocean range, every watch sold results in a donation to the Fabian Costeau Ocean Learning Centre, an organisation founded to preserve and protect the world’s oceans. This watch also has the marine nickname of tuna. This refers to the watch case resembling that of a tuna can with its jagged edges. The dial has a blue pattern complimented by white indexes and markers. Both the indexes and markers have luminous coating, allowing for easy visibility at night and at the depths of the ocean. Beneath the 12 o\'clock index is the ever present Seiko logo. Replacing the 4 o\'clock position is a simplistic date window. Both the date window and hands are powered by a solar movement, charging up a quartz battery. The dial is then protected by a thick black stainless steel and resin case as well as tough hardlex glass. Finally a black resin strap is fastened using a standard buckle. This epic timepiece is perfect for those who seek the thrill of diving with a water resistance of 200 meters or 20ATM.
