SEIKO Prospex Heritage ‘Turtle’ 1968 Re-Interpretation SPB317J1 SPB317

This watch shape is nicknamed by Seiko fans as a ‘turtle’ – its silhouette, side view and watch case back resemble a turtle with its curved comfortable shell. To divers, sea turtles are symbols of good fortune.

This design is a modern interpretation of the original 1968 Turtle, featuring a reinforced silicone strap with a rail pattern taken from the design of the original Turtle, while the date window’s position gives legibility without interfering with the indexes.

Prospex is a combination of the words ‘Professional’ and ‘Specifications.’ Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike.

Since launching Japan’s first diver’s watch in 1965, Seiko’s innovative watchmaking has changed global dive watch standards.
