Watch Description

Seiko recently released one new variant each to their incredibly popular and collectible “Samurai” and “Turtle” lines. The SRPD21 Turtle and SRPD23 Samurai are part of the highly capable Prospex series of professional dive watches, and these particular versions both include bright blue dials with intricate wave patterns (and a cameo appearance from the ultimate Alpha predator). These are both part of Seiko’s “Save the Ocean” series, with proceeds from sales benefitting the Fabien Cousteau Ocean Learning Center, a non-profit dedicated to raising awareness of ways we can protect ocean habitats and marine life.
