Some watches whisper. The HYT Conical Tourbillon Midnight Blue does not. It shows up in 5N gold, carries a small ocean of blue liquid on its dial, and spins a tourbillon at an angle most watchmakers would call reckless. Subtlety was never really HYT’s thing, and this new limited edition of just 8 pieces (ref. H03000-A) makes that clearer than ever.
Gold on the outside, chaos on the inside
The case pairs warm 5N rose gold with DLC-coated black titanium. It sounds like a simple styling choice, but it is really a stage direction. The gold takes the crown, the side grilles and the frame, catching the light wherever it can. The titanium, blacked out and quiet, steps back into the shadows. Nobody designed this case to compete for attention. It was designed to lose that competition on purpose, so the real star can shine: the blue.
And what a star it is. HYT’s signature fluidic blue runs through a borosilicate capillary tube, rising and falling to mark the hours in a retrograde display. It is essentially a tiny, very expensive science experiment strapped to your wrist, and it looks fantastic doing it.
Three spheres that never repeat themselves
If the hour display is the calm part of the show, the three spheres are the circus act. Positioned around the conical tourbillon, they are filled with blue liquid and spin at three different speeds: four turns a minute for the first, five for the second, six for the third. Since these speeds do not divide neatly into each other, the pattern never lines up the same way twice within an hour. It is choreography without a choreographer, and it is oddly mesmerizing to watch.
Right in the middle of it all, the conical tourbillon completes a full rotation every 30 seconds. That is fast for a tourbillon, and this one does not sit flat either. The spring-balance tilts 30 degrees from horizontal, the escape wheel sits at 15 degrees, and the pallet at 23 degrees. This tilted construction traces back to German watchmaker Walter Prendel, who built on the ideas of master watchmaker Alfred Helwig to try to improve rate stability with an oblique tourbillon. In the early 2020s, master watchmaker Eric Coudray, a Prix Gaïa winner, picked up Prendel’s research and pushed it further, giving HYT the technical base for the movement now ticking inside this watch.
A movement with a lot going on
The caliber 701-TC beats at 21,600 vibrations per hour (3 Hz) and is hand-wound, which feels appropriate for a watch that clearly does not believe in doing things the easy way. The tourbillon cage alone is built from 159 components. Add the dial’s 39 parts and the case’s 66, and the full watch reaches 750 components in total, every one of them checked and assembled by hand. For scale, that is roughly the part count of a small, extremely well-dressed machine.
Why the liquid, though
HYT was founded in 2012 around one unusual idea: use liquid, not hands, to show time on a mechanical watch. It sounds almost too simple, using fluid to tell time, until you realize how hard it is to make liquid behave predictably inside a watch case. The brand solved it with a glass capillary tube just 0.8 mm wide internally, a fluidic module that is 10,000 times more watertight than a watch rated to 10 ATM, and bellows thinner than a quarter of a human hair. Engineer Lucien Vouillamoz cracked that puzzle, and HYT has been running with it ever since.
The bottom line
The HYT Conical Tourbillon Midnight Blue is not a watch that tries to convince you with restraint. It convinces you by putting all of its technical ambition on full display and framing it in gold, literally. At CHF 355,000 and only 8 pieces, engraved HS-78 on the case back, it is not a watch many people will own. But it is exactly the kind of watch that reminds the rest of the industry why HYT exists in the first place: to prove that watchmaking still has room for a little bit of madness.
