Seiko SRPL51 Prospex Sea Samurai Diver Blue Dial Stainless

Seiko Prospex Samurai Blue Diver

Reference: SRPL51K1 / Caliber 4R35

The Seiko Prospex Samurai SRPL51K1 brings together aggressive modern dive-watch styling with the rugged reliability that has made Seiko one of the most respected names in professional dive watches.

Known among enthusiasts as the “Samurai” due to its sharply faceted case and sword-inspired hands, the Samurai series stands apart from traditional rounded dive watches with its bold architectural design and unmistakable wrist presence.

The SRPL51K1 features a striking deep blue monochromatic design with a matching blue dial and bezel, giving the watch a clean ocean-inspired appearance while maintaining the unmistakable tool-watch DNA of the Prospex line.

Powered by Seiko’s proven 4R35 automatic movement, this diver offers dependable self-winding performance, hand-winding capability, hacking seconds, and the durability expected from a true everyday mechanical sports watch.

Built to ISO dive standards with 200 meters of water resistance, a screw-down crown, and powerful Lumibrite visibility, the SRPL51K1 is equally at home underwater, on the road, or in a serious Seiko collection.
