Watch Review: Kaventsmann Hadal II

How do you choose your next watch to buy? Do you base it on the brand? Perhaps your decisions are based on certain specifics on design, such as case material, case size, bezel (ceramic insert, lume, ect) For me personally I base it on the overall physical design. As many of you know my personal preference tends to go towards those unique pieces, those outside of the box thinking types. Of course there are some traditional designs that I do enjoy still as well, rare but I do. There is definitely a love affair that I have with bronze. As I have surely mentioned in the past, what I truly appreciate about bronze is that it doesn’t like to stay stagnant in it’s life. This is something that I have come to put into motion into my everyday life. In my opinion no other material used for a watch case ages as beautifully as bronze do. Even scratches are a thing of beauty on a bronze case. Then the real thing of beauty comes through, patina, bronze’s life partner. Patina is natural beauty at its absolute best which adds a depth of character to a watch case that no other material can even come close to.

Today’s bronze bombshell is no other than the Hadal II handmade awesomeness from the masters at Kaventsmann. For those of you unfamiliar with Kaventsmann, here is a bit of information about them from their website: Kaventsmann was founded by maverick watchmaker Michael Fernandez who started his new venture of creating his own watch in a small garage.

The watches are entirely handmade in Berlin Germany, the work of just one man wanting to hand build a watch for his father’s birthday.

While studying engineering & construction technology he started to build watches in 2011.

His first watch model in 2011 the “Bathyal” made of Bronze CuSn8 passed a pressure-test of 280bar.

In 2012 he developed the deepest dive-watch made of Aluminium with a pressure resistance of 300bar. This prototype was also known as C-4 proofed watch, it was tested by some guys in Fort Bragg.

In March 2017 we passed a pressure test up to 1200bar /12000m /39370ft with our Kaventsmann HADAL II Bronze, the deepest Bronze watch ever.

In September 2017 we passed the 2nd pressure test to 1200bar , this time with a watchcase completely made of high strength aluminum, the deepest Aluminum watch ever.

In German, ‘Kaventsmann’ is a term used colloquially to describe hefty objects. It is also used to describe rogue waves, relatively large and spontaneous ocean surface waves that occur far out at sea.

Since 2017 Immelmann and Kaventsmann produce together in one workshop to put their knowledge together.

Only a few watches leave the workshop each month.

The Hadal II has a commanding presence as soon as you lay your hands and eyes upon it allowing a quick understanding why it holds the record for deepest diving bronze watch at 1200 bar. I will save some of you time right here, right now, if you are one of those people who put your watch buying decision on the size of a watch, you can stop reading and move on to save yourself some time. If you admire handmade horological creations that follow a personal individualized journey, then please keep reading. Everyone can buy what speaks to them by all means, but my reviews for with those like myself who appreciate the unique, small brands that still have that passion for creating unique pieces, sharing that horological love, unlike the big brands that the soul drive is for the almighty dollar.

The Hadal II is a bronze beauty and beast measuring an impressive 49mm x 25mm. Like anything in life there are those negative stubborn people who actively choose to live a sad existence just to troll while wearing their horse blinders, with the belief that think simply buying a watch is contributing something positive to this hobby and that bashing anything that they don’t like is a real contribution. For you open-minded folks who like to expand their horological palate and appreciate listening to other things besides their own voice let us continue exploring the Hadal II together, shall we?

The main part of the case on the Hadal II is a handworked solid piece of bronze. The caseback is stainless steel and is secured by several hex nuts creating a tight seal. Like the case itself, the caseback is also quite clean, void of unnecessary jibber jabber. I am definitely a sucker for an oversized screw down crown so of course the Hadal II crown is amazing in my opinion. My only complaint about the crown is when it’s fully open it has a bit more wiggle/wobble that I prefer my crowns to have. Other than the extra play, the crown is extremely easy to grip and operates smoothly for winding/time setting. Kaventsmann was definitely mindful when designing this watch as evidenced by the position and placement of the crown. This piece is remarkably balanced in terms of how it wears with comfort despite it’s size and weight. Even with the location of the crown Kaventsmann was still conscientious of protection with the crown guard and lug as the active protectors. The shortening of the drilled lugs allowed the Hadal II to sit well on my wrist without much overhang.

The massively thick tempered domed plexiglas crystal gives a great porthole view into the Hadal’s dial. The crystal is amazing without a doubt but the dial is even more awe-inducing. Typically blue is not my first choice of a dial color but this blue works extremely well on this piece. The sandwich style just adds to my personal appeal that attracts me to this piece. The style gives depth and the orange color of the bottom portion of the sandwich looks like rust. That rust color emanates an unmistakable sunken ship soulfulness. The raw brushed minute and hour hands truly accentuate that feel and the shape/size fit this dial unbelievably well. The length of all three hands meets my personal approval which allows optimal dial legibility and hitting all their designated positions also aides in functional timing. Legibility/functional timing can be done with ease in all environments, lighting situations and wrist angles.

The Hadal II is a fantastic horological beast in every way. This watch definitely had adopted the mantra of “go big or go home!” The German craftsmanship can be easily found throughout the Hadal II. Kaventsmann created the Hadal for those of you who have an obsession with deep diving watches. Theses watched are very rare with only 10 of each variant made and as you would expect with a quality handmade piece price is also a factor. If you are unable to find one on the secondary market, head over to Kaventsmann website as the new Triggerfish watch is up for preorder. Yes the crown stabilization could be improved upon, but let your mind be eased by the lifetime warranty that Kaventsmann watches hold.

Strap: made of AK47 assault rifle leather sling, manufactured in Hungary…

Best history of Dobra straps from the master himself.

Used by a great warrior, an ex USMC, now special commando forces, the guy who gave me the Kaventsmann Acanthurus and his Zlatoust Diver as a gift to show me how much is appreciating my straps…

So a sling that came from war and returned to war after being transformed in a strap… A strap that is not afraid of water, sweat and blood… A strap that will never let you down in the most rough situation…

The brown leather strap in the pictures are that creation from Dobra. It’s one of the best made straps that I have ever owned. Handmade with hand tools, no fancy pretty boy machines here. 8mm thick, yet this strap is ridiculously comfortable on the wrist. It was tested in all environments from below zero temperatures, around water, 24 plus continuous wear on my wrist at work, at play (hiking, fishing, working out) Dobra’s work is so important to him that his straps carry the weight of a lifetime warranty. He is a true artist and a real life badass.

Thanks to Michael for creating these beautiful beasts of the deep! Thanks to Dobra Strap’s for the badass custom AK-47 strap.

Thank you all for reading.

    • I first recommend opening your eyes if they are closed. Second, actually look through the review at the multiple pictures of the watch. Thirdly, try viewing the pictures on something bigger than a smart watch🤷🏻‍♂️

  1. Maz,
    I passed out because of so many good pictures and videos! Something about bronze that is gaining traction or had traction and I missed it.

    While not dive watches I am delving more and more into tritium lumed pieces. I am eyeballing the Nite Icon 208, blue on blue.

    Keep the reviews.coming!
