Celebrating 10 years of partnership and 60 years of PADI, Seiko have unveiled a new Prospex Dive Watch in the organisation’s colour and logo.
Of all the attributes Seiko is known for — mass appeal, remarkable design, and accessible pricing — they all pale in comparison to its sheer reliability. Since 1881, the Japanese powerhouse has established a reputation for robust mechanical timekeeping. Regardless of the situation, there’s always a Seiko built to endure it with you.
In the golden era of watchmaking, the all-important proving ground was diving. Seiko boldly entered the scene in 1965, with the ever-iconic 62MAS establishing its professional specifications.
Such strongly built timepieces were eventually given a shortened designation — Prospex — in 2007. But just a year after the 62MAS debuted, in 1966, the Professional Association of Diving Instructors (PADI) was founded in a bid to standardise recreational scuba diving.
It was inevitable that the worlds of Seiko and PADI would collide. Establishing themselves as cornerstones of sea exploration and safety, they entered into an official partnership in 2016. This year, celebrating the partnership’s 10th anniversary and PADI’s 60th birthday, Seiko has introduced a new model to mark both milestones.
A Deep Dive
The new Seiko Prospex King Turtle PADI Limited Edition, Ref. HBB002, is housed in a 45mm-wide, 47.7mm-long, and 13.2mm-thick case. It’s a case silhouette that has long defined the King Turtle line-up, spreading wide across the wrist while maintaining a fairly stubby lug-to-lug measurement for wearability.
From the outset, not much has changed: the 4:30 crown remains, as does the knurled unidirectional bezel fitted with a blue ceramic insert. A date magnifier also makes itself apparent, enhancing legibility for the day and date complications within.
The watch comes on a steel bracelet by default, complete with a folding clasp and diver’s extension. This allows the watch to be worn over a wetsuit where needed, while also serving as a micro-adjustment system for fluctuations in wrist size.
If that’s not your thing, though, don’t worry: a black rubber strap is also provided, permitting a lighter style of wear by comparison. Water-resistant to 200 metres, it’s the perfect watch with which to commemorate Seiko and PADI’s dedication to the diving world.
Water World
And since it’s a celebration of both brands, of course there’s a unique dial finish to go along with it. Borrowing from the colour scheme of the PADI logo, blue forms the base of the dial, with red appearing on the seconds hand and the “Diver’s 200m” text at six o’clock. Lumibrite on the hands and markers takes care of low-light timekeeping — an essential for divers as they descend further into the ocean.
Looking closer, however, you’ll also notice a globe motif beneath the sunray-brushed blue finish. As you may have guessed, this is also a feature of the PADI logo. It’s details like these that Seiko refuses to miss, adding another feather in the cap of this tribute to the organisation.
Reliable As Ever
As is the case with all King Turtle models, the caseback hides the inner workings of the watch from view. But it should come as no surprise that the movement within is the Cal. 4R36, Seiko’s catch-all movement in the entry-level segment. Beating at a comfortable 3Hz (21,600VpH) and backed by a 41-hour power reserve, it remains as capable as ever.
There’s really not much more to say about the Cal. 4R36 that hasn’t already been said. It’s a capable movement that has become one of Seiko’s most reliable players in the industry. Yet it does make me curious what would happen if Seiko were to offer this model with a 6R-series movement instead. Sure, it would be a little more upscale, but a PADI 60th anniversary tribute feels like justification enough for an upgrade.
Initial Thoughts
Limited to 8,000 pieces, this new Seiko Prospex King Turtle PADI Limited Edition is bringing the celebration to as many wrists as possible. While that production number is rather steep, it leverages the global reach that Seiko enjoys across the watch world. The brand has long been the perennial entry-level value king, and with this new, robustly built watch, it isn’t about to stop now.
But beyond the impressive spec sheet, it also brings more eyes back to PADI as a whole, which has contributed tirelessly to the safety of scuba divers worldwide. In that sense, it’s a respectful nod to the shared diving legacy of both brands in a way that remains appealing to the everyday consumer.
