# H. Moser & Cie. Streamliner Flyback Chronograph – A Bold Step into Automatic Chronography The 2019‑launch of the H. Moser & Cie. Streamliner Flyback Chronograph Automatic (reference 6902‑1200) announced itself as a statement piece: a limited‑run of just 100 watches that would combine the brand’s celebrated minimalist aesthetic with a technical first‑in‑the‑world movement. The result is a 42.3 mm stainless‑steel cushion‑shaped case that houses the HMC 902 calibre – the world’s inaugural automatic chronograph featuring a central‑display flyback. Priced around US $42 000, the Streamliner sits squarely in the upper‑tier of independent horology, promising both visual impact and pioneering engineering. Below we break down how the watch lives up to its ambitions, where it shines, and where the compromises become evident. ## Design & Case The Streamliner’s case is unmistakably a “form watch.” Its 42.3 mm cushion silhouette departs from the more conventional round or tonneau profiles that dominate the chronograph market, giving the piece a subtle, sculptural presence on the wrist. Crafted from polished stainless steel, the case feels solid yet retains a refined lightness, a balance that H. Moser & Cie. has honed across its collections. A standout design decision is the integrated bracelet. Rather than a detachable strap, the watch’s bracelet is forged as a single unit with the case, echoing the seamless continuity of the case’s curvature. The bracelet’s links are slim and polished, delivering an elegant, dress‑ready look while remaining comfortable for daily wear. The downside, however, is the loss of strap interchangeability – a point to consider for collectors who enjoy swapping bands to suit different occasions. The dial continues the minimalist language. Though the source data does not detail dial coloration, the Streamliner is known for a clean face that emphasizes the central chronograph display. The central seconds hand, together with a minute counter positioned at the 6 o’clock position, reinforces the watch’s “central‑display flyback” concept. The hour markers are discreet, allowing the chronograph function to take visual priority without overwhelming the dial. Water resistance is rated at 120 m, a respectable figure for a chronograph of this complexity, ensuring the watch can handle everyday exposure to rain or a brief swim without compromising its delicate mechanisms. ## Movement & Performance At the heart of the Streamliner lies the HMC 902 calibre, a self‑winding automatic movement developed in collaboration with Swiss movement specialist Agenhor. This partnership produced the world’s first automatic chronograph that combines a central display with a flyback function for both minutes and seconds. In practice, the flyback allows the wearer to reset the chronograph instantly without stopping the mechanism first – a feature traditionally reserved for high‑end quartz or manual‑wind chronographs. The HMC 902 delivers a power reserve typical of modern automatic movements, though the source data does not specify the exact number of hours. Its accuracy, while not quantified in the provided material, can be inferred to meet the standards expected of a Tier‑1 independent brand, especially given the involvement of Agenhor, a respected movement developer. The calibre’s layout is deliberately visible: the central chronograph seconds hand is driven directly from the movement, reinforcing the watch’s claim of “central display.” This architectural transparency not only serves an aesthetic purpose but also showcases the engineering ingenuity required to synchronize flyback functionality with an automatic winding system. One potential drawback is the complexity inherent in any automatic chronograph. While the Streamliner’s design aims for simplicity, the added gears and springs required for flyback may demand more meticulous servicing over the long term compared with a conventional three‑hand automatic. ## On the Wrist Measuring 42.3 mm, the Streamliner occupies a sweet spot for many wrist sizes, offering a presence that is noticeable without bordering on the oversized trend. The cushion case shape distributes the watch’s mass evenly, contributing to a balanced feel. Lug‑to‑lug distance is not explicitly listed, but the integrated bracelet design typically results in a slightly shorter overall length, which can be advantageous for those with smaller wrists. Comfort is a strong suit of this model. The bracelet’s slim links sit flush against the skin, and the polished steel feels cool without being abrasive. The watch’s weight, while solid, is not oppressive, thanks to the careful engineering of the case and movement. Because the bracelet cannot be detached, the watch maintains a consistent aesthetic throughout the day, eliminating the temptation to swap to a sportier strap that might clash with its dress‑oriented design language. However, for owners who enjoy a more casual look, the lack of strap flexibility could be perceived as a limitation. On the wrist, the central chronograph display is instantly readable, and the flyback function can be engaged with a single push of the chronograph reset button, a gesture that feels both purposeful and satisfying. The watch’s 120 m water resistance also means it can be worn in most everyday situations without fear of moisture ingress. ## Value & Verdict With an approximate retail price of US $42 000, the Streamliner positions itself among the premium offerings of independent watchmaking. The limited production run of 100 pieces adds an element of exclusivity, which can be appealing to collectors seeking a distinctive piece that stands out in a crowded market. From a value perspective, the watch delivers several unique selling points: * **Technical Innovation** – The HMC 902’s central‑display flyback chronograph is a world‑first, offering a function rarely found in automatic watches. * **Design Cohesion** – The cushion case, integrated bracelet, and minimalist dial create a unified aesthetic that is instantly recognizable as a H. Moser & Cie. creation. * **Build Quality** – Polished stainless steel, 120 m water resistance, and a movement developed with Agenhor speak to a high level of craftsmanship. Conversely, the price tag must be weighed against a few considerations. The integrated bracelet limits customization, and the mechanical complexity may entail higher long‑term service costs. Additionally, the limited edition nature, while exclusive, could affect resale dynamics; the market for such niche pieces can be less predictable than for more widely produced models. **Verdict:** The Streamliner Flyback Chronograph is a bold, technically impressive watch that lives up to its claim of pioneering an automatic central‑display flyback. For enthusiasts who value innovation, a cohesive design language, and the cachet of a limited edition, it offers a compelling proposition at the $42 k price point. Those who prioritize strap versatility or are wary of the servicing demands of a complex chronograph may find the trade‑offs less appealing. Overall, the Streamliner stands as a testament to H. Moser & Cie.’s willingness to push boundaries while maintaining the brand’s signature elegance.
