Streamliner Cylindrical Tourbillon Skeleton Alpine Limited Edition

H. Moser & Cie. presents the Streamliner Cylindrical Tourbillon Skeleton Alpine Limited Edition, the first fruit of its collaboration with Alpine Motorsports. For this timepiece symbolising the union between the two brands, H. Moser & Cie. wanted to create a design attuned to the aesthetic tastes of the stable’s F1 drivers and endurance racing team: fine engineering visible from every angle, a bold character, a touch of colour, and a comfortable strap which fits all wrists and is made from rubber for guaranteed durability. The result is a roaring success: an entirely chiselled three-dimensional sculptural watch which looks spectacular and is perfect for everyday wear thanks to its balanced proportions and 12 ATM water resistance.

It is a very fitting choice if you think of the high-speed trains that inspired both the name and the curves of this line. And, for the occasion, the Manufacture has removed all superfluous material, creating a fully skeletonised version that enables the movement to be admired from every angle. Embodying precision and exceptional engineering, the Streamliner Cylindrical Tourbillon Skeleton Alpine Limited Edition is an ode to transparency and three-dimensionality. At the heart of this timepiece is a one-minute flying tourbillon fitted with a cylindrical hairspring at 6 o’clock, showcasing the expertise of H. Moser & Cie.’s sister company, Precision Engineering AG. Invented in the 18th century, the cylindrical hairspring rises perpendicularly around the upper stem of the balance spindle. A frequent feature of marine chronometers at the time, it offered the advantage of being developed concentrically. The cylindrical hairspring – fitted with two Breguet overcoils attached at two points – reduces the friction of the pivots and improves the isochronism properties, all the more so if the hairspring is combined with a tourbillon, as is the case here. Nowadays, the cylindrical hairspring is challenging to produce because it requires expertise that has been lost. Each cylindrical hairspring is shaped by hand, which takes ten times as long as a traditional hairspring. H. Moser & Cie. loves to play with contrasts,…
