SEIKO PROSPEX SRPJ93K1 GREAT BLUE SAMURAI SCUBA PADI AUTOMATIC SPECIAL EDITION MEN WATCH

Seiko Prospex SRPJ93K1 — "The Great Blue" PADI Special Edition Diver's Watch

The Seiko Prospex SRPJ93K1 "The Great Blue" is a PADI Special Edition in the Samurai 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 Samurai name refers to the angular, blade-like case design first introduced in 2006 — sharp shoulders, distinctive lugs, and a geometric character that sets it immediately apart from the rounded silhouettes of the Turtle and Sumo. The blue dial and matching blue silicone strap create a cohesive, ocean-connected aesthetic that carries the Great Blue narrative from dial to wrist, and the 43.8mm case at just 12.8mm slim makes this one of the most wearable Diver's 200M automatics in the PADI lineup.

Powered by the in-house 4R35 automatic calibre with hand-winding capability and a 41-hour power reserve, the SRPJ93K1 delivers the full Prospex diver's specification — Diver's 200M water resistance, ceramic unidirectional rotating bezel, and screw-down crown. The sapphire crystal with magnifier ensures the date display is clearly readable at any angle and in any light. Lumibrite on the hands and hour markers delivers the legibility needed at depth. Presented with a special edition PADI box.

Why You'll Love It

The SRPJ93K1 is the most distinctive of the three Great Blue PADI case shapes — the Samurai's angular design is immediately identifiable on the wrist, and the matching blue silicone strap creates a dial-to-strap colour story that the stainless bracelet Turtle and Sumo variants do not share. At 43.8mm and 12.8mm slim, it is notably compact for a Diver's 200M automatic — the slim profile makes it comfortable through a full day of wear in a way that larger dive watches cannot match. The ceramic bezel is virtually unscratchable, the sapphire crystal with magnifier keeps the date legible at any angle, and the 4R35 calibre is one of Seiko's most proven and reliable automatic movements. A PADI diver with a genuinely distinctive character.

SRPJ93K1 vs SRPK01K1 vs SPB375J1 — Which Great Blue PADI Should You Choose?

All three models are Great Blue PADI Special Editions with ceramic bezels, sapphire crystals, blue dials, and Diver's 200M water resistance. The differences are in case shape, calibre, and strap. The SRPJ93K1 has the Samurai angular case with the 4R35 calibre, 43.8mm diameter, 12.8mm slim profile, and blue silicone strap — the most distinctive case shape and the slimmest wearing. The SRPK01K1 has the Turtle cushion case with the 4R36 calibre, 45mm diameter, and silver stainless bracelet — broader and more comfortable for all-day wear. The SPB375J1 has the Sumo case with the 6R35 calibre and 70-hour power reserve — the most capable and most expensive of the three. Same Great Blue PADI credential, three completely different case personalities.

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 SRPJ93K1 carries that legacy forward in a PADI Special Edition that combines one of Prospex's most distinctive case shapes with the Great Blue design narrative.
