Product Details
Seiko Prospex SRP789K1 is the K1 version of Seiko’s iconic Turtle automatic diver. Its cushion-shaped stainless-steel case, black dial and black/red “Coke” unidirectional bezel give the watch the unmistakable look of Seiko’s classic professional dive-watch lineage. Oversized LumiBrite markers and hands provide strong low-light legibility, while the day/date display at 3 o’clock adds everyday practicality.
Inside is Seiko’s proven 4R36 automatic movement with manual winding and stop-seconds functionality. The movement uses 24 jewels and delivers approximately 41 hours of power reserve. The watch is protected by Hardlex crystal and a screw-down crown and screw case back, with 200-meter diver’s water resistance.
