Sorry no more offers available

Part of Seiko’s “Save The Ocean” series, this Seiko Prospex Turtle Special Edition has a striking blue dial. Proceeds from sales benefit the Fabien Cousteau Ocean Learning Centre, dedicated to raising awareness of ways we can protect marine life and ocean habitats.

Inspired by a popular Seiko model from the 1970’s, the Turtle has a large cushion shaped case reminiscent of the shape of a turtle’s shell. Although 45mm in diameter, the case is heavily contoured which makes it feel more comfortable than you would expect for a watch of this size.

Water resistant to 200 m/660 ft the Seiko Prospex Save The Ocean Turtle Special Edition has all the attributes you would expect from a professional Diver’s watch. The graded blue dial is a lighter colour at the top getting darker blue at the bottom, reminiscent of the depths of the ocean. High-visibility hour markers and hands coated in Lumibrite shine out even in poor light. Additionally, a legible minute track is at the extreme edge of the dial. Surrounding the dial, there is a blue uni-directional turning bezel.

Equipped with an automatic 4R36 calibre movement, the Seiko Prospex  Save The Ocean Turtle Diver Watch is an absolute must for anyone who cares about our oceans and is looking for a comfortable, well-made Diver’s watch. For complete peace of mind, it is also covered by a two year manufacturer’s warranty.
