The Seiko 5 Sports SRPL57K1 is an automatic men's watch with a green sunray dial. The dial has gold-tone hands and index hour markers, with minute markers around the outer rim. The design is inspired by the original 1970s Seiko 5 Sports. The hands and markers are coated with white LumiBrite so they can be read in low light.
It is powered by the Seiko Caliber 4R36 automatic movement with 24 jewels. The movement winds itself and can also be wound by hand. It has a power reserve of about 41 hours. A day and date window sits at the 3 o'clock position, and the day can display in English or Japanese.
The case and bracelet are stainless steel. The case has a matt finish with polished edges, a fixed bezel, and a curved, scratch-resistant Hardlex crystal. A transparent caseback shows the movement. The bracelet closes with a fold-over clasp with a safety release. The watch is water resistant to 100 meters (330 feet).
