H. Moser & Cie. pushes the boundaries of high-end watchmaking once again with the creation of the one-and-only Streamliner Cylindrical Tourbillon Skeleton Alpine Unique Piece. All proceeds from this auction will be donated to the AQUA PEARLS Foundation to support global access to clean drinking water. This watch draws inspiration from the brand’s Streamliner collection, featuring a striking blue DLC-coated stainless steel case that encapsulates the purity of water, while integrating the signature colors of the BWT Alpine Formula 1 team. The interplay of blue and pink details showcases a unique style.
At the 12 o’clock position of this watch, there’s an elegantly curved small dial made of pink sapphire, seamlessly incorporating the signature shades of BWT, which beautifully contrasts with the sapphire crystal glass, making the overall design stand out. The dial features an openwork design, forgoing any brand logos to highlight H. Moser & Cie.’s understated luxury aesthetic. The hour markers are coated with Super-Luminova® for glow-in-the-dark visibility, while the blue hour and minute hands are crafted from Globolight® material, ensuring readability even in low light conditions. Paired with a pink rubber strap, it further enhances the striking contrast and sporty vibe.
When it comes to the powerhouse, this watch is equipped with the HMC 811 fully skeletonized automatic movement, showcasing the beauty of its mechanical structure from both the front and back. With a frequency of 21,600 vibrations per hour and a 74-hour power reserve, it stands out in precision. Positioned at 6 o’clock is a cylindrical balance wheel with a one-minute flying tourbillon, securely held by a blue skeleton bridge, blending mechanical artistry with cutting-edge technology. The transparent case back design allows the wearer to admire the completely skeletonized golden oscillating weight and masterful chamfering craftsmanship. Moreover, this watch boasts an impressive water resistance of 120 meters, highlighting its exceptional durability.
This one-of-a-kind watch will be auctioned on The Auction Collective platform, with all proceeds donated to the AQUA PEARLS foundation established by BWT, providing clean drinking water to vulnerable communities worldwide. This charity auction not only showcases H. Moser & Cie.’s pursuit of excellence in watchmaking craftsmanship but also reflects the brand’s commitment to sustainability. The winning bidder will enjoy customization options, including swapping for a blue arch-shaped subdial or choosing between a blue rubber strap or a pink camo rubber strap, further highlighting their personal style.
