The Streamliner Tourbillon Pierre Gasly by H. Moser & Cie. is a masterwork that blends horological finesse with the essence of personality, conceived through a genuine synergy between the manufacture and the Formula 1 driver himself. This isn’t a piece manufactured to capitalise on a name; it’s an authentic extension of Gasly’s taste for detail, technical prowess and understated distinction.

Chocolate Fumé and Subtle Intimacy
Examining the Streamliner’s dial is a journey into refined mystery. The “Chocolate fumé” finish, developed in close dialogue with Pierre, evokes a nuanced depth that feels both powerful and immensely delicate. Its surface is animated by a rich sunburst pattern, offering gradients that shift under the sapphire crystal, capturing ambient light with restrained drama. The H. Moser & Cie. logo is rendered in transparent lacquer, maintaining purity without any obtrusive branding, ensuring the dial remains a canvas of expression.

The hour and minute hands, elegant in red gold, are filled with Globolight inserts, delivering legibility in low light while staying delicately in tune with the dial’s colour palette. Applied red gold indices bring a hint of three-dimensionality, each edge crisp yet modest. In the ultra-limited reference 6805-0411, one finds a baguette-cut ruby subtly set at ten o’clock, a private allusion to Gasly’s racing number, softly gleaming amidst the dial’s chromatic restraint.

The Movement – Calibre HMC 805 Tourbillon
At the heart of this timepiece lies the HMC 805 automatic calibre, a testament to the manufacture’s ability to merge artistry and technological advancement. The movement’s architecture is both robust and visually engaging, with a skeletonised oscillating weight in 18-carat red gold, carrying the Moser logo in dignified relief. Measuring 32.0 mm in diameter and 5.5 mm in height, this movement quietly houses sophistication within compact boundaries.

The finishing stands out with partially skeletonised bridges decorated in an anthracite hue and Moser’s trademark double stripes, a detail for those who cherish discreet beauty. A one-minute flying tourbillon holds court at six o’clock, supported by an airy skeletonised bridge, its “balletic motion” as Pierre himself describes, hypnotic to behold. Even the invisible is lavished with attention: the movement is fitted with a double hairspring, engineered with precision by Precision Engineering AG, ensuring enhanced isochronism and minimised positional error, all in pursuit of unwavering accuracy.

With a minimum power reserve of three days and automatic bi-directional pawl winding, the calibre rounds out its technical excellence with steadfast reliability, suitable for those who demand both performance and refinement.

A Streamlined Streamliner
Streamlined in Red GoldTurn the watch in hand, and the case reveals itself to be a sculpture of some complexity. Shaped from 5N red gold and measuring 40.0 mm in diameter, the case sits comfortably; not overbearing, but solid and reassuring. The highly polished flanks, gently curved, meet a slightly domed sapphire crystal, offering distortion-free views of the dial and tourbillon spectacle. The watch’s profile, 10.3 mm without, 12.1 mm with crystal, ensures that wearability isn’t sacrificed for the sake of drama.

The see-through case-back, constructed of sapphire crystal, presents a voyeuristic glance into the calibre’s intricacies, framed with balance and poise. Water resistance is rated to 12 ATM, ensuring a proper sporting bent without forsaking its luxurious origins. The screw-in crown, adorned with an engraved “M,” is another minute detail that speaks to Gasly’s involvement, and to the manufacture’s uncompromising standards.

Partnership and Sophistications
The Streamliner Tourbillon Pierre Gasly encapsulates the interplay between sport and sophistication, woven into the fabric of a partnership founded on authenticity and mutual respect. Available in two configurations, one with a supple chocolate rubber strap for everyday versatility, and another, far rarer, with an integrated red gold bracelet, the fate of each piece is already entwined with stories of performance and personality. Launched to coincide with the electric atmosphere of the Singapore Grand Prix, it is a fitting tribute: this timepiece, poised on Pierre’s wrist, is at once precise, personal and resolutely uncompromising.

H. Moser & Cie.’s approach yields a Streamliner that is far from generic. For devotees of true watchmaking, and for admirers of discreet charisma, this Tourbillon stands as a quietly brilliant work, echoing not just technique but the very presence of the man whose name it bears.
