H. Moser & Cie. has crafted the Streamliner Cylindrical Tourbillon Skeleton Alpine Unique Piece, which will be auctioned to benefit the private non-profit foundation AQUA PEARLS, established by BWT (Best Water Technology) and its CEO Andreas Weissenbacher in 2016, supporting its mission to provide access to clean drinking water worldwide. BWT drives positive change beyond the racetrack. In a world where access to clean water should be a fundamental right, this shared initiative emphasizes the responsibility to act, not just observe.

Following the success of its Streamliner Cylindrical Tourbillon Skeleton Alpine Limited Edition Pink Livery, H. Moser & Cie. has crafted a unique piece inspired by this series, with an exclusive blue DLC treatment on its case—a hue inspired by the purity of water. Sporting the colours of both BWT Alpine Formula One Team and BWT, the Streamliner Cylindrical Tourbillon Skeleton Alpine Unique Piece mixes blue and pink accents.

At 12 o'clock, the skeletonised main dial is topped with a small domed dial in corundum, following the curve of the sapphire crystal and sporting the signature pink colour of BWT, a bright and distinctive shade enhanced by the clarity of the corundum, or ruby, used.

Emanating timeless elegance, this model has no logo, emphasising its aesthetic purity and exclusivity. The indices feature Super-Luminova®, while the inserts above the blued hour and minute hands are made of Globolight®, for perfect legibility even at night. As for the strap, H. Moser & Cie. has opted for a pink rubber. The beauty of the automatic calibre HMC 811 - fully skeletonised on both the front and on the reverse side - is accentuated by the lightness of the one-minute flying tourbillon fitted with a blue cage bridge matching the hands, and a cylindrical balance-spring which spins at 6 o'clock.
