The Seiko Prospex PADI 60th Anniversary Limited Edition King Turtle HBB002K1 celebrates 60 years of the Professional Association of Diving Instructors (PADI), the world's largest diving training organisation, while marking a decade of partnership between PADI and Seiko Prospex. Known affectionately by Seiko enthusiasts as the "Turtle" thanks to its distinctive rounded case profile, this limited-edition diver's watch pairs a robust stainless-steel case and bracelet with a striking blue ceramic unidirectional bezel and vivid blue dial featuring the PADI logo and anniversary-inspired red and blue accents. LumiBrite hands, dot and baton hour markers, a date display and a screw-down crown ensure outstanding visibility and performance, while the watch is supplied with an additional black accordion-style silicone diver's strap, inspired by Seiko's pioneering 1975 design, for added versatility in and out of the water. Powered by a reliable calibre 4R36 automatic movement with 24 jewels and a 41-hour power reserve, the King Turtle is built to withstand demanding underwater adventures with 200-metre water resistance and a durable screwed case back. Protected by scratch-resistant sapphire crystal with an anti-reflective coating on the inner surface and limited to just 8,000 pieces worldwide, each watch is finished with a specially engraved limited-edition case back and commemorative PADI 60th Anniversary hang tag. Combining Seiko's renowned dive watch heritage with the spirit of exploration shared by divers around the world, this exceptional timepiece is a fitting tribute to one of diving's most iconic partnerships. • Powered by the caliber 4R36 automatic movement with 24 jewels and a power reserve of up to 41 hours. • Presented on a silver stainless steel bracelet with push button deployment clasp. • Scratch resistant sapphire crystal glass with anti-reflective coating on the inner surface. • 45.0mm case width. • 200 metre water resistance.
