This is a new Seiko automatic dive watch that is nicknamed the Great White Shark Samurai. This Seiko SRPD23 Samurai model is part of the new Save the Ocean collection. Part of the proceeds from the sale of this collection will be donated to the non-profit Fabien Cousteau Ocean Learning Center that raises awareness of ways to preserve and protect the planets waters and endangered marine life. It has a distinctive graduated blue dial with a texture that resembles the surface of water. This is offset with blue bezel that has a grey hue that defines the first 15 minutes. The bezel insert also has some fine grooves (hard to see in images) that give this Samurai watch a unique and very distinctive look.

It features a Seiko 23 jewel automatic (4R35) movement, a date display, highly luminous hands and markers treated with Lumibrite for awesome low light visibility, a screw down offset crown, a uni-directional diving bezel with luminous PIP at 12:00, Hardlex mineral crystal and a solid etched, screw-down case back. The 4R35 Seiko movement is self-winding and it can be hand wound and hacked. The movement has a 41 hour power reserve.
