Nicknamed the “Turtle” by Seiko fans, this watch gets its name from its case shape, which resembles the smooth, curved shell of a sea turtle. The rounded profile, side view, and case back all echo this iconic silhouette. In diving culture, sea turtles are often seen as symbols of luck and endurance — a fitting inspiration for a timepiece that has earned the admiration of countless diving enthusiasts. The Seiko Prospex collection is built for those who thrive on adventure — whether in the ocean depths, high in the sky, or across rugged landscapes. Since creating Japan’s very first diver’s watch in 1965, Seiko has consistently pushed boundaries, setting new standards for professional-grade dive watches worldwide.
