Seiko Prospex watches are designed for sports lovers and adventure seekers whether in the water, in the sky or on land. Since launching Japan’s first diver’s watch in 1965, Seiko’s innovative technology has changed global dive watch standards. 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 is the diver’s watch that, just like the sea turtle, is loved by many diving enthusiasts. The uni-directional rotating bezel with precise and safe operation prevents accidental rotation for accuracy, particularly when diving. The accordion-style silicone strap combines high durability and comfort - a strap design invented by Seiko in 1975 as a practical solution to the expansion and contraction of a diver's wrist at different depths.
