Seiko enthusiasts affectionately dub this watch shape as the "turtle" due to its resemblance to the curved and comfortable shell of a turtle when viewed from the side and back. For divers, sea turtles hold symbolic significance, representing good fortune. Just like its namesake, this diver's watch is cherished by numerous diving enthusiasts. Seiko Prospex timepieces are crafted for sports aficionados and adventurers, whether they're exploring the depths of the sea, soaring through the sky, or traversing the land. - Calibre Number 4R36 - Automatic Movement – Powered by the movement of the wearer - 41 Hours Power Reserved - 200 Meters Water Resistant - 13.4mm Case Thickness - 44.3mm Case Size - Stainless Steel Case - Urethane Strap - Hardlex Glass - Screw Down Crown - Rotating Bezel – One Way - Date, Day of the Week - Hand Winding Capability
