Prospex PADI King Turtle 60th Anniversary - Ltd Ed 8000pcs Ref. HBB002J

Seiko and PADI have shared a legendary partnership, producing iconic hits over the years like the beloved Samurai, the Sumo, and the recent, refreshing 1965 Heritage Divers. The year 2026 marks a massive dual milestone for both organizations, celebrating 10 years of their formal partnership alongside the grand 60th anniversary of PADI itself. To honor the occasion, Seiko has introduced the Prospex PADI King Turtle Limited Edition, bringing the long awaited upgrades that collectors and enthusiasts have been craving.

Prospex for Seiko basically means "Professional Specification" that their timepieces in this category  are built with very high standards to be used by professionals. One of the most popular releases in recent years is probably the remake of the Seiko 6309 (circa 1976-1988) commonly known as the turtle. The original 6309 divers are pretty rare given its short 12 years production lifespan. Although there are many examples in the market, there are less than a dozen that are original. It is no wonder the new Prospex turtles are so popular among Seiko and dive watch collectors. And today we will dive into the details of the "crowned" Turtle that speaks of much refinement done to it.

Before we get started, with much request since we introduced Seiko JDMs, we decided to bring in the MADE IN JAPAN Turtles meant for the Japanese Domestic Market, denoted by the "J" in the reference number and the "MADE IN JAPAN" at 6 on the dial. The Prospex PADI 60th Anniversary is a never seen before design within its King Turtle shell. This JDM model made available only in Japan. And comes with a selectable choice of English or Kanji date. The difference might be subtle but this means a lot for Seiko collectors.

Next, the connection between Seiko and PADI (which stands for Professional Association of Diving Instructors), the world's most trusted scuba diving training organization, also merits attention. Established in 1966 and based in the US, PADI offers an array of courses ranging from entry-level to relatively advanced recreational diver certification courses. This association is reported to have awarded over 27 million scuba certifications, in over 6,300 diving centers globally. 2016 marked the beginning of the partnership between PADI and Seiko via the first special edition, the ever reliable PADI Turtle SRPA21J1. Other editions with novel designs and updated materials have since surfaced. Today we introduce the Seiko Prospex PADI King Turtle 60th Anniversary.

The PADI King Turtle was released in mid of 2026, yet with another oceanic dial theme. The overall look of the Turtle is one of a kind, quirky and unique given its unusual case silhouette. Powered by Seiko's automatic caliber, 4R36, operating at 21,600 BPH (3 Hertz) with hacking and hand winding capabilities. It has 24 jewels with a power reserve of 40 hours.

The 200m water resistant stainless steel case measure 45mm case without the crown, but has a lug to lug length of only 47.7mm, and a height of about 13.2mm; along a lug width of 22mm. The short lugs to lugs length means this watch wraps around the wrist on all(small or big) wrist sizes like a glove making it extremely comfortable.

Notably, as of the "crown" of the Prospex Turtle, the bezel is one of the newly introduced blue ceramic insert with the evergreen Seiko's large printed markings on it in contrasting white colour. Now that the bezel's grooves gets more angular and distinct, it allows better grip and rotates buttery smooth into 120 positions has little to no free play in a clockwise direction. Sitting atop of the bezel is another Seiko's latest upgrade; a flat sapphire crystal with the elongated magnifying Cyclop for its day/date display.

Mixture of case finishing for a premium feel

Mixture of refined satin-brush finish on the surface and Seiko high polishing on the sides, giving it a somewhat premium tool watch feel. The screw-down crown at four o'clock is easy for time setting. Moving to the back of the watch, the screw down case back allows 200m water resistant, and is also brushed, featuring the recognizable tsunami emblem that is staple on the other Seiko divers. The case does comes with drilled lug-holes to allow swapping of straps with ease.

Without a doubt, the true centerpiece of the new King Turtle is the commemorative 60th Anniversary blue dial. It proudly showcases a distinctive globe motif taken from the official PADI emblem, extending across the face of the watch and finished with a rich sunray texture. Staying faithful to the timeless classic Samurai's design, the prominent hour markers and bold hands are generously treated with legendary Seiko Lumibrite, ensuring peerless legibility in the deep sea or at night. The maritime color scheme is brilliantly tied together by a sharp red seconds hand and corresponding red "DIVER'S 200m" script at 6 o clock, adding the perfect amount of energetic contrast.

Seiko's LumiBrite

The Seiko Prospex King Turtle Limited Edition comes paired with a 22mm matching stainless steel bracelet, beautifully finished with satin brushing and accented by polished connecting links. In addition to this robust steel option, the package includes an extra high strength silicone strap featuring Seiko's signature accordion design. This flexible layout ensures an exceptionally secure fit and superb comfort whether worn over a diving suit or directly on the wrist for daily wear.

In all, Seiko once again replicated another successful version of its all new King Turtle, and the PADI 60th Anniversary Edition is probably one of the more exciting dive watch from Seiko in 2026. And one of the few watches that is worthy to be in any dive watch collection. With its excellent price point and good value for money, it is a watch that will probably find itself onto the wrist of most Seiko buyers. The unique sea blue dial design based on the partnership serves as an essential factor that your purchase of one is actively supporting a brand who seeks to continue its dive-watchmaking legacy.
