Pre-SIHH 2016: IWC - Big Pilot’s Heritage Watch 55 and 48

Delma Blue Shark III 4,000-Meter Dive Watch Review

Do you like extraordinarily intense watches? What about actually quite weighty ones? Some particular subtleties and an old name sprinkled on top sound okay, as well? At that point support yourself, ’cause kid do we have the watch for you. This is an audit of the Delma Blue Shark III 4,000-meter dive watch.

The Delma Blue Shark III likes a test — thus do I. It can go 4,000 meters (13,120 feet) under the outside of water, which is around 3,996 meters more than I’d actually dare. However, hello, exploring a 47mm-wide, 18.5mm-thick, 295-gram watch is such a test that I like, apparently.

If you have ever been only a few meters deep submerged, you’ll recollect that exceptional sensation of a waterway burdening you. Presently, attempt to increase that sensation by around 1,000. That’s the sort of circumstance where the Blue Shark III will cheerfully continue ticking — despite the fact that you will have been crushed into jam. Is this applicable? In the event that you like such a stuff, at that point of course it is! In the event that not, at that point you will need to realize that Delma makes a large group of a whole lot all the more reasonably estimated, and still very fit, dive watches. The Blue Shark III is for those stricken by madly over-designed dive watches.

On an individual note, I recall, around 10 years prior, as an absolute beginner watch-darling, I was in wonder of watches that were designed to dive truly deep in the sea. Similarly there is an otherworldly thing in the examples of a guilloché dial of a Breguet watch, or in the plan of another age Rolex development, a similar breath of “unbelievable engineering” waits around these go-anyplace watches similarly also. At a cost somewhere in the range of €1,990 and €2,090 for the Delma Blue Shark III, the brand says you can get a watch that was made to play with the best and hardest in its class of absurd depth dive watches — however at a small amount of the price.


Established in 1924 in Switzerland as A. & A. Gilomen S.A, the company got renamed to Delma in 1966, named after one of its four effective product offerings. Today, Delma works in a real sense a stone’s discard from such industry goliaths as Breitling, ETA, and other eminent companies like Eterna, Fortis, Epos… and a couple of other ETA offices, no doubt. Its old neighborhood, Lengnau, and its (once more, plainly) nearby neighbor, Grenchen, is home to some legitimate Swiss watchmaking forces to be reckoned with. Delma has tenaciously chipped away at becoming well known as a brand firmly committed to the universe of the untamed waters — even its “racing” assortment, you can tell, is focused on boat hustling and less for stuff on wheels.

The first Blue Shark, or the Delma Blue Shark I, appeared in 2011 as a “progressive execution diver’s watch with water protection from 3000 m/9900 ft that encompassed the most recent headways in usefulness and strength.” Not simply a corona item, the Blue Shark was a watch to be worn by those interested by contributions from the external edge of the dive watch fragment. After five years, the Blue Shark II saw the expansion of a refreshed bezel for simpler activity with gloved hands, and 2020 presents to us the Delma Blue Shark III, with one more 1,000 meters’ worth of steadfastness and roughness by one way or another designed into the package… in my brain, only for boasting rights.


What I first need to feature is the general quality feel of this watch — something else, this significant, all-encompassing sensation may get lost among all the insane specs. Indeed, the surprising weight has something to do with it.

But one thing that has consistently enraged me with generally those strong, yet less expensive (€500-€1,000) microbrand dive watches that have dispatched themselves into the market lately, was that wherever I contacted, there was a sharp edge or an ineffectively completed surface. The Blue Shark III costs more than those, in any case, conversely with my assumptions, that isn’t due to its over-the-top water opposition rating. It’s likewise on the grounds that it is that vastly improved made across all components. The wristband feels smooth, the bezel looks sharp and feels hearty, and the case has surfaces a whole lot more pleasantly characterized than what is seen at a lower value point. You do, obviously, anticipate that these things should be perceptibly more pleasant at this value point — yet the way that they really are is worth mentioning.

At 47mm-wide and 18.5 mm-thick, all that water opposition is stuffed into a cumbersome, thick watch. At the point when I state “dense,” I mean the vibe of the thing both on and off the wrist. With each connection in the hardened steel arm band introduced, this watch with a tempered steel case and dark DLC-covered steel bezel gauges an astounding 295 grams (or about 10.4 ounces). More on coming about wearability in a bit.

Extra seals and a long string secure the advantageously estimated crown.

The case comprises an enormous crown on one side and a flush helium get away from valve on the other. Since when you’re decompressing on your dive, attempting to get back from the jam state to that of an individual, helium gets caught inside the watch case and, except if given another exit plan, will push the sapphire gem out of the case, delivering even the most rough dive watches broken. The helium get away from valve (or HEV) is a protected single direction road for helium to get away from the case, however not for water to supplant it.

The bezel, despite the fact that DLC-covered steel, looks and feels significantly more like brushed artistic, so Delma has accomplished top work on that. The case profile directly under it seems to be an industry standard “okay” in its stature — and that’s on the grounds that another quarter of the thickness of the Delma Blue Shark III comes from the domed caseback underneath.

The caseback is pointedly laser-engraved with the picture of an irate shark, the individual predetermined number out of 500 pieces (for every one of the six shading combinations, and the 4,000-meter water opposition rating is referenced twice, in addition to a third time on the dial, just no doubt. Behind this thick square of steel carries on an ETA 2824-2 with a Delma custom rotor, just actually to be seen by watchmakers at watch administration focuses equipped for testing watches to 4,000m water resistance… Not numerous such places are out there.


Beyond the 4,000m rating, which clearly is cool, undoubtedly, there are extra highlights of the Delma Blue Shark III worth referencing. Carry distance is 22mm, which implies that once you’ve found a powerful enough cowhide lash or elastic tie, you can shake the Blue Shark on those, as well.

The most secure and least demanding to-utilize screw plan you’ll ever see for this reason — except if you lose the screwdriver.

What I truly delighted in utilizing were the unique screws that Delma depends on to make sure about lashes and wristband joins. Essentially called “security screws,” Delma supplies two screwdrivers for the bigger screws that fix the arm band/lash to the carries, and a more modest one for the screws between the connections of the wristband. I was suspicious from the start, as I had not seen the purpose of utilizing an exclusive screw instead of ordinary ones.

One of these incredibly made screws per carry secure the wristband or strap.

That was uniquely until I checked these out: This screwhead is the best I have ever utilized with regards to forestalling the slipping of the screwdriver and doing costly and frightful harm to the hauls or connections. The heads are unshakable and turn changing ties and measuring arm bands from a bad dream into a protected and, indeed, fun experience for even the lousiest wannabe watchmakers out there, for example, myself.

Legibility is incredible, because of the enormous hands, dependably determined by the durable ETA 2824 —  this is the point at which the workhorse notoriety of this type comes to play. The hands are long and wide, making them significantly heavier than those found on more modest, more filigree watches, thus including additional strain the development. Readability is obstructed by the thick and intelligent gem. This is improved by the dark dial; the more splendid shaded dial references of the Blue Shark III will consider this to be less of an issue.

The wellbeing catch of the arm band is so ludicrously estimated, the collapsing part could envelope a more modest Reverso easily. Albeit wide and thick, the catch in any case is proportionate to the watch itself, which is an outright should, taking into account how weighty the watch head is. The three-interface arm band feels smooth and extremely refined to the touch — nothing of the unpleasantness and unsavory sharpness that you deliberately get from dive watches valued beneath the Blue Shark III. Once more, for 2,000 Euros, you do anticipate a pleasantly made wristband — however the way that you do really get it is, once more, worth mentioning.

Rotating the bezel and unscrewing the crown are your fundamental methods of associating with a watch head appraised to 4,000 meters of water opposition — thus even, these ordinary highlights become significantly more exceptional. The fastener in the uni-directional bezel is decently uproarious and has a springy vibe that make it charming to utilize. It’s clever to perceive how the bezel swells over the watch head itself, like it was ensuring the association among bezel and case in anticipation of the massive pressing factor at those insane depths.

Last, however unquestionably not least, is the introduction Delma adds to the Blue Shark III. It must be the most flawlessly and extravagantly introduced watch that I have ever found in this value point. A huge wooden box, a bespoke additional elastic tie, and a bunch of pleasantly machined devices that are a delight to go through all add to introduction comparable to watches valued many occasions over this one. Genuinely, very well done.


If you like a hefty, and I do mean, heavy watch, at that point you’ll appreciate wearing the Delma Blue Shark III. I for one incline toward lighter watches and, in the wake of wearing my Exospace B55 with a titanium case and titanium wristband, the 316L, quality steel case and arm band of the Blue Shark III was essentially an over the top strain for me. It would take an uncomfortably close attack of the wristband to stop the watch head wobbling and pushing down on the highest point of my hand when my arm is swinging alongside me when strolling. Wearing it on the elastic tie has had a perceptible effect for the better.

If I had a lot thicker wrist, at that point I’d expect the heaviness of the watch head was appropriated over a bigger territory and a superior, safer fit I’m sure could be accomplished. Notwithstanding, for me and my 17.5cm (about 6.8 inch) wrist, I’d need to search for something more compact and lighter from Delma, similar to the Periscope, which is an incredible third lighter than the Blue Shark III and still offers 500 meters of water obstruction. Goodness, and it is just about a large portion of the cost, with the equivalent movement.

I wish Delma would begin utilizing titanium for a portion of its able dive watches, on the grounds that with its scrupulousness and interesting, however not very idiosyncratic, plans and bundling, it could put forth an enticing defense for a more comfortable diver in this section. However, I digress.

One shortcoming of the Delma Blue Shark III is the nature of its lume. An insane dive watch ought to, I think, by all methods have extraordinary lume in any event — and a flippin’ light show on its dial, ideally! While accusing the lume of my amazingly incredible Profoto streak at its most extreme setting, I could make this lume shine, however it blurred and demonstrated its messy surface rapidly. The hands are OK ish in the manner they gleam, yet the records on the dial show the quieted, messy sort of radiance that only isn’t comparable to the nature of in a real sense all other components on this watch, including the dial itself, which has delightful silver-outlined and raised lists, numerals and date window. So the general nature of the dial is extraordinary — however the equivalent can’t be said of the lume.

One positive in such manner is that even the bezel itself is lumed, bumping the Blue Shark III closer to that previously mentioned light show I was alluding to. It takes a ton of openness to a great deal of incredible light to charge the orange markers of the bezel — however go into a dim room, flight of stairs or rear entryway from a radiant day outside and it sure adds a ton to the pleasant experience that is wearing this watch.


The Delma Blue Shark III is a colossal and enormously competent watch. On the off chance that you are on the lookout for very good quality G-Shocks, Vostok Europes and other tough and, ahem, liberally proportioned watches, at that point you will most likely need to think about the Blue Shark III. It offers extra degrees of refinement in pretty much every component both all around. It feels great to utilize, and its nature of execution is particularly in accordance with its value point — including its lovely presentation.

If you can take the huge heave and the liberal extents, the Delma Blue Shark III offers a lot to present a strong defense for itself in this value portion. In the event that it is all in all too much for you to deal with, all things considered for me, given its emphasis on nature of execution and introduction, another model from this little, committed company will probably be a superior option.

The Delma Blue Shark III is estimated at €1,990 and €2,090, contingent upon the rendition, and you can learn more at .
