SEIKO PROSPEX SRPK01K1 GREAT BLUE TURTLE SCUBA PADI AUTOMATIC SPECIAL EDITION MEN WATCH

Seiko Prospex SRPK01K1 — "The Great Blue" PADI Special Edition Diver's Watch

The Seiko Prospex SRPK01K1 "The Great Blue" is a PADI Special Edition diver's watch in the Turtle case — a collaboration between Seiko Prospex and PADI, the Professional Association of Diving Instructors and the world's most recognised diver's training organisation. "The Great Blue" references the vast open ocean that PADI certification is designed to unlock, and the blue dial and silver stainless steel case express that reference directly in the design. The Turtle cushion-shaped case provides the comfortable, distinctive wrist presence that has made this silhouette one of the most beloved in the Seiko Prospex family for nearly five decades.

Powered by the in-house 4R36 automatic calibre with hand-winding capability and a 41-hour power reserve, the SRPK01K1 delivers the full Prospex diver's specification — Diver's 200M water resistance, ceramic unidirectional rotating bezel, and screw-down crown — in the Turtle's distinctive cushion-shaped case at 45mm and 13.22mm slim. The sapphire crystal with magnifier ensures the day-date display is clearly readable at any angle and in any light. Lumibrite on the hands and hour markers delivers legibility at depth and in low light. Presented with a special edition PADI box.

Why You'll Love It

The Turtle case shape is known for its exceptional comfort at 45mm — the cushion proportions sit closer to the wrist and distribute the case width more naturally than a standard round case — and the PADI Special Edition designation connects it to the professional diving community through the world's most recognised certification body. The ceramic bezel is virtually unscratchable in daily use, the sapphire crystal with magnifier keeps the day-date readable, and the Lumibrite ensures legibility from dusk to depth.

The Seiko Prospex Story

Prospex is a combination of the words "Professional" and "Specifications." Seiko Prospex timepieces are designed to be practical, reliable, and durable — built to meet the high standards required in extreme environments for sports lovers and adventure seekers alike. The story begins in 1881, when Kintaro Hattori founded a clock and watch shop in Ginza, Tokyo — the business that would become the Seiko of today. Since 1965, when Seiko created Japan's first diver's watch, the Prospex dive line has stood for underwater precision and reliability. The SRPK01K1 carries that legacy forward in a PADI Special Edition that honours the Great Blue and the professional diving community it serves.
