VIDEO: The Seiko Prospex SRPJ35 & SNJ039 bring new colours to cult classics
D.C. HannaySeiko is back with two new limited editions in their Prospex tool watch line, and they both feature a bright new colourway that evokes the brilliant hues of tropical fish. This time, the new colours are featured on Seiko’s classic Turtle diver, and the big, bold “Arnie” analogue/digital model. Let’s dive in and have a look at these wonders of the deep.
SRPJ35K
The case

The dial
The Turtle’s dial legibility is one of its biggest selling points, and this one is no different. A matte black finish provides the perfect backdrop for those bright white indices to pop against. Interestingly, there’s now a tiny segment of a marker to the right of the day/date window, in order to meet updated ISO criteria. A turquoise minute hand adds a cheerful accent to a legitimate tool watch, and the seconds hand retains the lollipop as a counterweight, although I secretly wish it were at the business end like the original model. Seiko fans love their nicknames, and it looks like “Lagoon Turtle” is the frontrunner for this new colour combination. As is customary throughout Seiko’s Prospex line, the hands and dial markers are charged with the company’s eyeball-searing LumiBrite, and offer fantastic legibility both above and below sea level. The crystal is Seiko’s mineral glass formulation, known as Hardlex, perfectly functional, but not as scratch resistant as sapphire (although it has higher impact resistance).
The movement
Timing duties are handled by the Seiko manufacture 4R36 automatic movement, a reliable caliber that has proven itself many times over. It’s so popular, you’ll find it in countless microbrands as well. Accuracy is stated at -35/+45 seconds per day, but real-world usage can often see it performing much better. Hacking and handwinding are both standard, and Seiko is one of the few manufacturers offering both a day and date display in a tool watch. Action from the guarded screwdown crown at 4 is smooth and drama-free, and that nicely-sized crown offers terrific grip.
The bracelet
The three-link stainless bracelet offers an Oysterlike look, with brushing throughout, but for the polished accents on the outer links. The links are solid and serviceable, although sizing would be much easier with screws rather than the pin/collar arrangement. The clasp is perfectly functional, with twin pushbuttons and a foldover lock, but it would benefit from milled construction, if only for the more upscale feel it offers. Fortunately, the Turtle is also a Monster…a strap monster that is, and it would look fantastic on a blue or green tropic strap in the right shade.

The case

The dial
The matte black dial is all business, but has a slightly different countenance than its mechanical brethren, since it needs to allow light through to charge the solar cell. It’s not a significant difference functionally, and retains its fantastic legibility. Hands are similar to the Turtle version’s, and as far as analogue/digital watches go, it leans far more analogue. There’s plenty of functionality in the small display at the top of the dial, which we’ll discuss next.
The movement
The movement is a solar-powered quartz caliber H851, and features both a traditional handset, and a digital multifunction display. Besides the analogue handset, the multifunction allows reading of hours, minutes, seconds, plus the functionality of a stopwatch, alarm, second time zone, and even a perpetual calendar that requires no resetting until the year 2100. And although you may be long gone by then, it’s nice to have that going for you. A full charge should give you six months of power reserve, and you’ll probably never have to worry about it running out if you leave the watch on a windowsill periodically.
The strap
This sea monster sports a blue silicone strap that coordinates nicely with the colour on the bezel. It’s high-quality, with ribbed texture near the lugs offering a bit of give, and a reassuringly solid buckle. The strap keeper is also quite solid, as it’s made from vented stainless, and you might find it a bit unforgiving against your wrist. Luckily, the 22mm lug width means you have near-infinite options should you decide to switch things up. I recommend seeking out something in vulcanised Italian rubber.
The verdict
Seiko’s no stranger to special editions, and this colourway represents one of their most attractive in recent memory. Which one you choose depends on whether you’re a fan of traditional mechanical timepieces, or prefer the grab-and-go convenience of a solar-powered quartz. Aesthetics come into play, too, and while I’m a huge fan of the Turtle, there’s no denying the action-star presence of the Arnie. The cool, oceanic colours of both models absolutely transport the wearer to a relaxed, tropical state of mind, even if your diving is of the desk variety. But it doesn’t hurt to dream, does it?
