Seiko Prospex PADI Turtle SRPE99K1 The PADI timepiece collection is exclusive to Seiko, as the only global watch brand to design a range of professional diver’s watches in official colors featuring the PADI logo. PADI (The Professional Association of Diving Instructors) is the world’s leading scuba diving training organization, unifying divers around the globe who share a passion for adventure and a love for the ocean. 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. Seiko Prospex watches are designed for sports lovers and adventure seekers in the water, in the sky or on land. Since launching Japan’s first diver’s watch in 1965, Seiko’s innovative watchmaking has changed global dive watch standards.
