The Seiko Prospex SRPL51 Samurai Diver is a robust, professional-grade diver’s watch engineered for both underwater adventures and daily wear. Powered by Seiko’s reliable 4R35 automatic movement (with manual winding and stop-second hand), it offers about 41 hours of power reserve and precise timekeeping. The bold blue dial, paired with a matching uni-directional bezel and luminous LumiBrite hands/markers, ensures excellent readability even in dim light or underwater. Built with a tough 41.7 mm stainless-steel case and bracelet — with a secure three-fold clasp and diver extension — along with Hardlex crystal and 200 m water resistance, the SRPL51 is ready for diving, swimming or everyday use with classic diver-watch durability and Seiko’s legendary craftsmanship.
