H.MOSER & Cie PIONEER CYLINDRICAL TOURBILLON SKELETON SPICED AQUA 3811-1203

Open-heart haute horlogerie by H. Moser & Cie.

The Pioneer Cylindrical Tourbillon Skeleton Spiced Aqua (ref. 3811-1203) embodies the most radical and spectacular expression of the Pioneer collection. Here, H. Moser & Cie. hides nothing: the movement becomes the dial, the mechanics become sculpture, and color acts as a revealer of emotion.

Housed in a steel case with a sporty and refined design, water-resistant to 120 meters (12 ATM), this piece combines contemporary robustness with watchmaking virtuosity. A watch designed for action, but crafted like a kinetic work of art.

An exceptional movement: the HMC 811 caliber

At the heart of this creation beats the HMC 811 manufacture caliber, entirely skeletonized and developed in-house. A true technical manifesto, it features a flying tourbillon with a cylindrical balance spring, a complication that is extremely rare in contemporary watchmaking.

Unlike a traditional flat balance spring, the cylindrical balance spring improves isochronism and regularity of movement, while offering a hypnotic visual depth. Suspended in the center of the movement, the tourbillon seems to float in space, accentuating the sensation of lightness and transparency.

Here, there is no luminescent flange: the light emanates directly from the movement, its openworked bridges, its finishes, and its three-dimensional architecture.

A powerful and contrasting Spiced Aqua aesthetic

The signature Spiced Aqua is expressed through a bold chromatic contrast. A small domed orange subdial, positioned above the skeletonized movement, indicates the time with immediate legibility. It is subtly adorned with the H. Moser & Cie. logo in transparent lacquer, almost invisible, faithful to the anti-conformist spirit of the manufacture.

The indexes and hands, featuring turquoise Globolight® inserts, add a touch of modernity and ensure excellent visibility, day and night. The whole creates a striking visual tension between extreme technicality and chromatic energy.

A manifesto watch, combining independence and innovation

The Pioneer Cylindrical Tourbillon Skeleton Spiced Aqua 3811-1203 is neither an exercise in style nor a cosmetic variation. It is a declaration of horological independence, a piece that proudly proclaims the mechanical expertise of H. Moser & Cie., without compromise or concession to traditional codes.

At once sporty, artistic, and radically contemporary, this watch is designed for collectors in search of authenticity, rarity, and pure mechanical emotion. A sculpture in motion, destined for the wrists of those who want to see the heart of fine watchmaking beat.
