The new H4 RC44 in the perfect environment. HYT©

Each time I’m allowed to write something about the Hydro Mechanical Horologists called HYT, I’m very excited. If you are familiar with the brand, I’m guessing you totally understand this excitement. If you don’t have a clue what HYT is or does, you should be ashamed of yourself. For years and years and years the way of showing time was the same. An hour hand here and a second hand there. Very spectacular and almost boring if it weren’t for the special materials and shapes used to distract your eyes.


HYT is for time display what the tank was at the end of World War I, the atomic bomb for chemical warfare and the end of the Berlin wall for Germany. Now, you probably think I’m exaggerating, but if that’s what you think, you still haven’t researched the name HYT. You see, why would you create a timepiece with hours and second hands which is quite ‘easy’, if there’s a far more difficult approach. I mean, using liquid to display time is rather crazy and unbelievably difficult. Then again, using liquid to – accurately – display time is mission impossible. Even Tom Cruise agrees with me on that opinion. HYT doesn’t care less and just does what they do best; using liquid in their crazy time machines to tell you it’s time for a cup of tea or a party.

After this short description of what HYT does, do you understand why I’m excited when writing about them? I hope you do. If you don’t, well.. then you don’t. The latest creation coming from the masterminds behind the brand is the HYT H4 RC44. A reincarnation of the H4, specially created for the celebration of 10 years of RC44 class. The RC44 class is a special class in sailing that saw the light of day ten years ago, in 2006. HYT partnered with Russel Coutts – the sailing specialist from New Zealand – and is the only hydro mechanical watch and natural partner for this monohull. Crossing the oceans since 2015 and having its own RC44 Championship Tour. A perfect match if you ask me. Since HYT’s biggest value is liquid and the monohull isn’t much at all without liquid. Ladies and gentlemen, a match made in heaven.


The new HYT H4 RC44 has almost exactly the same characteristic as the regatta. Using a very light carbon case like the monohull does, the same colour scheme and unique blue liquid, this watch matches perfectly around the wrist of the sailors. A cool detail of this watch: the second wheel has the same golden colour that can be found on the bar raised on the monohull when it is winning. It’s not that I have that much knowledge when it comes to sailing, the people at HYT told me about that detail. Nevertheless, it’s a nice detail that will please the sailing-minded watch enthusiast.


The overall look of this H4 is very skeletonized. A transparent sapphire crystal disk displays the minutes with a black minute hand. At the 2 o’clock position, you will find the power reserve indicator divided in four different segments showing the balance of the 65 hours of autonomy. If you ask me – this watch is once again a great addition to the HYT family. I really like the way they play with mechanics and the way time is displayed in their watches. The liquid gives it a very special look and feel and besides that, all their watches are very well finished. The same goes, of course, for this H4 RC44. What I find very interesting with HYT watches is the fact that they placed a layer of SuperLuminova® underneath the capillary, ensuring good readability of the hour indication when it’s dark. It gives the watch the effect of carrying luminous liquid, if you don’t think that’s cool, we should stop talking watches after this sentence.

The watch case exists out of carbon featuring grey anthracite tones, the same ones that can be found in the bezel that displays the titanium DLC-coated emblem characteristic for HYT. Furthermore, the strap of the RC44 is made out of NOMEX. NOMEX is a material made out of Kevlar and designed to withstand the most harsh conditions. The same material is used in sailing hulls and used particularly for its ability to form high resistant honeycomb structures. A material that fits perfectly not only for the watch but also for its purpose and environment. It’s a watch that has multiple bonds with the world of sailing, not only through its name but also through its design and the materials that have been used. To be honest, I do not really mind this sort of characteristics, of course, it’s nice to know that HYT really did their best to fit this watch as good as possible for its purpose. On the other hand, and this is something I’ve said for way too many times, a watch has to attract you or not. This H4 RC44 attracts me from the very first moment. You could say that’s because I’m a fan of everything with a HYT stamp on it, and you would be very right too. The amount of technological ingenuity and the designs, it’s just perfect. HYT does a very good job within the world of watches and this H4 RC44 is no exception.
