Explorers of the underwater realms have become somewhat spoiled with choices when it comes to excellent tool diver watches. From Citizen’s Blue Promaster to Seiko Prospex SRP775, a wide range of options are available to those looking to take their watches into the dark blue depths.
A relatively new brand has taken the opportunity to provide an answer to each of the market’s many demands, including outstanding resilience, precision, and an overall reliability, that imperative factor for all seasoned divers.
Their name is Deep Blue and their line ‘Pro Seadiver’ has already won the hearts of many looking for robust and dependable timepieces for their professional underwater activities. And it comes as no surprise. These watches are technically advanced, superbly well-built, and don’t lighten one’s wallet in vain. Let’s go over the details.
There are three bezel color options – orange, black & blue, and black & green. In my opinion, the orange one is the most attractive, with that sporty, eccentric edge. Speaking of the rotating bezel, it’s wonderfully made, with 120 audible, satisfying clicks and some very nice notch detailing spaced out in six places. This gives the watch a unique gear-like look.
Material-wise, the whole case is constructed from high-grade 316L stainless-steel. It measures 46mm in diameter when you don’t take the crown into account. A pretty hefty look which will wear large but won’t have too much of a wrist presence. Also, the case back is non-exhibition, which is perfect for a diving watch. At the bottom of an ocean, you’ll much prefer security to aesthetics. The watch is certified to a whopping 1000m.
Anti-reflective sapphire crystal is protecting the dial; flat instead of domed which increases the legibility by a notch. It will come in handy underwater where you’re likely to bump and scratch the watch against all kinds of objects. Say, for example, you bump the watch into a rock – that impact resistance will prevent the glass from cracking and leaking water, which in turn can save you a trip back to the surface.
You can tell the crystal is nice and thick by tapping the surface. If it resonates a high-pitched clink then it’s mineral crystal or a thin sapphire. Not only is the glass on the Seadiver chunky, it also boasts anti-reflective coating for glare prevention. Finally, another feature fitted into the case is the manual Helium release valve for SAT Diving. Tough construction all over.
The plain blue dial, alongside the typical diver elements such as the large round hour markers, offers some unique twists, too. The minute hand, for example, is outlined in bright orange, matching the bezel and providing an added touch of legibility.
All elements of the face, excluding the day and date complication at 3 o’clock, feature a generous coating of Lume Superluminous paint. The glow is bright and won’t fade out that easily.
Driving the Seadiver is the 24-jewel Seiko NH36 movement. An automatic, hand-winding, and hackable powerhouse with a staggering 41 hours of reserve.
Normally, watches in this price range have Seiko NH or Miyota 82xx movements behind them and these do the job extremely well. With an accuracy within -20 to +40 seconds per day, they’re reliable and offer long and consistent accuracy with their solid power reserve.
Head-to-head, there’s very little difference between the movements, perhaps the only way you could tell them apart is by comparing the sweep smoothness. Models with Miyota under the hood tend to tick at a higher beats per hour (bhp) frequency, allowing for a more gentle movement of the seconds hand.
Out of the box comes a high-grade, solid stainless steel bracelet with a push-button clasp and four removable links. Rather than using the standard pin-and-collar mechanism for the links, Deep Blue opted for the more expensive screw pins, also to be found on each lug.
The company’s styling on the double-secured clasp is a nice touch and indicates a high level of attention to detail. Keep in mind that, if for some reason you’d like to replace the bracelet, it won’t be a quick change as most bracelets won’t fit into the narrow lug gap on the Seadiver.
To sum up my thoughts on the Deep Blue Pro Seadiver, I think this is a great tool watch to which any serious diver should give a thought. Compare its specifications to any other pro watch in this price range and you’ll be hard-pressed to find a brand that offers more than Deep Blue. Its solid construction, visually appealing design, generous use of material, and a proven, reliable movement mix very well into a 1000m water-resistant sports piece. Lively, sturdy, and reliable. Perfect for your next underwater adventure.
