SEIKO PROSPEX SRPE99K1 PADI TURTLE MEN WATCH

Seiko Prospex SRPE99K1 — PADI Automatic Diver's Watch

The Seiko Prospex SRPE99K1 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 Turtle cushion-shaped case has carried a devoted following since its introduction in the Prospex lineup, and this PADI edition pairs it with a striking blue dial that connects directly to the ocean environment it is built to perform in. At 45mm with a 13.4mm profile and a silver stainless steel bracelet, this is the most accessible PADI Turtle in the City Chain lineup — the entry point into the PADI Turtle family.

Powered by the in-house 4R36 automatic calibre with hand-winding capability and a 41-hour power reserve, the SRPE99K1 delivers the full Prospex diver's specification — Diver's 200M water resistance, unidirectional rotating bezel, and screw-down crown. Lumibrite on the hands and hour markers ensures readability at depth and in low light. The Hardlex crystal provides reliable scratch resistance for active daily use, and the day-date display adds practical everyday function. Presented with a PADI Special Edition box.

Why You'll Love It

The SRPE99K1 is the PADI Turtle for those who want the full PADI credential and the Turtle case comfort at the most accessible price point in the lineup. The 4R36 calibre is one of Seiko's most proven automatic movements, the Diver's 200M rating is the full professional specification, and the Turtle cushion case distributes its 45mm diameter across the wrist in a way that makes it considerably more comfortable to wear all day than the dimensions suggest. The blue dial is the natural PADI colour choice, the Lumibrite handles low-light legibility, and the PADI Special Edition box marks it as a collaboration piece worth keeping. A capable, community-connected PADI diver at an accessible entry point.

SRPE99K1 vs SRPK01K1 — Which PADI Turtle Should You Choose?

Both models are PADI Special Edition Turtle divers with blue dials, Diver's 200M water resistance, and the 4R36-family calibre in the same 45mm cushion case. The key differences are in the crystal and price. The SRPE99K1 has a Hardlex crystal and standard bezel — the more accessible everyday Turtle. The SRPK01K1 "The Great Blue" has a sapphire crystal with magnifier and a ceramic bezel — higher specification, higher price. If crystal quality and the ceramic bezel are important, the SRPK01K1 is the upgrade. If the PADI Turtle credential in a capable everyday package is the goal, the SRPE99K1 delivers it.

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 SRPE99K1 carries that legacy forward as the most accessible PADI Turtle in the Prospex lineup.
