The Seiko SRPL15 is a newly improved version (fully redesigned and smaller) of the Seiko Prospex Diver's watch from the Samurai collection. The Seiko Samurai was introduced in the early 2000's and then was discontinued, it was then relaunched with some modifications in the 2010's and is renowned for its large size, robust feel, and angular bezel. For the 20th anniversary, Seiko has redesigned the model to be smaller, slightly robust, and features a new shape with tapered, slimmer lugs. The new Samurai is available in red (SRPL11), black (SRPL13), and black with burnt eggshell indexes on a rubber strap (SRPL15).
