There is something particularly Moser about taking a watch already built around an absurd amount of visible mechanics and deciding that what it really needs is a ceramic case. Today, I’m taking a look at the new H. Moser & Cie. Streamliner Tourbillon Skeleton Ceramic Alpine Limited Edition. It’s the third project born from the brand’s partnership with Alpine Motorsports. This time around, we’re getting a 40mm anthracite-gray ceramic Streamliner, a completely skeletonized HMC 814 movement, blue-finished bridges and mainplate, and a blue Alcantara integrated strap. Sitting at 6 o’clock is a one-minute flying tourbillon with Moser’s double hairspring, and the whole release is limited to just 100 pieces. On paper, it sounds like someone took every Moser buzzword, threw them into a blender, and gave us this beast. More on that in a bit.

H. Moser and Alpine started collaborating in 2024 with the Streamliner Cylindrical Tourbillon Skeleton Alpine Limited Edition. That watch was very much about putting the mechanics on display. That first model used the HMC 811 and its cylindrical hairspring. Then came the Streamliner Alpine Drivers and Mechanics Editions, developed around the needs and aesthetics of Alpine’s racing operation. So there is actually a progression here rather than three watches with the same blue paint and a racing logo slapped somewhere on the case. The first was about mechanics, the second about performance and function, and this new one is about materials. That makes the ceramic case more than a color change. It is the point of the watch. And that is where this collaboration gets interesting. If you’re going to build a watch around performance, you eventually have to talk about what it’s made of.

Ceramic: A surprisingly good fit for the Streamliner

Ceramic is not new territory in watchmaking, but Moser is getting into the habit of ticking every industry box. The anthracite-gray ceramic case gives the Streamliner a harder, more technical personality without messing with the collection’s “fluid” nature. This 40mm case has a 12.8mm total profile, including the 1.8mm-thick domed sapphire crystal. It also offers a display case back, a screw-down crown with an engraved M, and 12atm water resistance. Moser goes between polished and satin-finished surfaces across the case, which matters because ceramic can easily become one big chunk of dark material. Then, there is the blue Alcantara integrated strap, bringing the Alpine connection into the picture without turning the watch into F1 merch for your wrist. Anthracite and blue are very much male-motorsports-coded, but they’re a cool combination.

There is also a practical argument for the material. Moser describes ceramic as lightweight, highly scratch-resistant, hypoallergenic, resistant to oxidation, and unlikely to develop the patina you see on many metals. Those are familiar ceramic advantages, but they make sense here because the Streamliner has always been a watch built around its case architecture. If you’re going to spend all that time getting those curves right, putting them in a material designed to keep its appearance is only logical. And this isn’t Moser’s first ceramic experiment. The brand already used the material in the Streamliner Tourbillon Concept. This Alpine edition, then, continues an idea that fits the collection. The difference is that now, the case frames a completely openworked movement, meaning the ceramic has to support the show rather than steal it.

Then you notice what’s happening underneath…

The case might be the headline, but the movement warms my watch-nerd heart. Moser has taken its HMC 814 manufacture caliber and skeletonized essentially everything you can reasonably skeletonize without turning the movement into expensive spaghetti. The mainplate and bridges are finished in blue, the barrel is openworked, the gold oscillating weight is fully skeletonized, and diamond beveling catches the light around the architecture. No dial hides any of this. You are looking straight through the watch at the machinery, which is exactly what the Streamliner Tourbillon Skeleton concept is about. Skeletonization is particularly effective here, as instead of adding another layer to explain what is going on, Moser removes the layer completely.

The HMC 814 is a 32mm-wide, 5.5mm-thick automatic movement running at 21,600 vibrations per hour. It has 28 jewels, 167 components, a bidirectional pawl-winding system, a fully skeletonized gold rotor, and a minimum power reserve of 72 hours. At 6 o’clock, a one-minute flying tourbillon contains a skeletonized bridge, while the blue finishing ties the architecture directly into the Alpine palette. The hands and indexes use Globolight inserts for a strong visual signature and legibility. Then, there is the double hairspring, developed and produced by Precision Engineering AG. Moser says it compensates for variations in the center of gravity as the springs expand, improving precision and isochronism.

Final thoughts

This might be the most convincing direction Moser and Alpine have taken together so far. That’s not because it has the most obvious racing references. Quite the opposite, actually. This one works because the Alpine connection has been filtered through what Moser usually does well. The anthracite ceramic makes sense for the Streamliner, and the blue skeletonized movement suits an Alpine collaboration. The flying tourbillon and double hairspring give the watch enough serious watchmaking to justify the spectacle, and the Alcantara strap ties it together without making it feel like a souvenir from the paddock. At 100 pieces with a price on request, it won’t be a watch most people casually find. But that’s beside the point. Moser didn’t make a generic motorsport watch and decorate it with a racing logo. The brand is pushing the partnership through the Moser filter — technical, colorful, slightly excessive, and somehow elegant.
